Day 2 tires--- what are you looking for?

[SmallHurst]

Most of you guys know that the Goodyear Polyglas are being reproduced in L60-15's. Is there a size that is needed for the Day 2 group? I have had a couple of people mention the L60-14. Any other votes or suggestions?? No promises, but I do converse with Kelsey quite a bit!

[Hemicolt]

I don't know what the conversion size would be, but these two sizes should be popular with the Day 2 crowd.

[Hemicolt]

I looked at the Kelsey chart and it looks like a G60/15 may be close to the 235/60/15, but the rim recommended rim width on the G60 shows 7". The 235/60 can go to a 8.5" rim.
8" to 10" rims are seen on alot of Day 2 cars. The two tire sizes above would cover those.

[SmallHurst]

235/60/15= F60-15
275/60/15= L60-15

Both of these sizes are covered by Kelsey/Goodyear. What sizing needs to fill a gap?

The L-60's work better on the wider rims, but 8" will do fine.

[Hemicolt]

Is it possible for the L60-15 to be pulled in to far at the side walls with an 8" rim, causing the contact patch not to be evenly planted on the road surface, out on the tread edges?

I'm running L60-14's on 7&quot; rims. I'm not saying it's right but they seem to be fine. To me, that's what they did back in the day.

Here is a perfect example of what I'm talking about. How wide are those rims.....6&quot; maybe 7&quot;?


http://i300.photobucket.com/albums/nn2/brkyard/Dragway%20Pictures/4270011.jpg


Let a little air out of them and they'll hook!!!!


http://i300.photobucket.com/albums/nn2/brkyard/1969%20Chevelle/ByronOct162010.jpg


Most cars ran 14&quot; rims back in the day, that's why it's so hard to find vintage 15&quot; these days. L60-14's were THEE tire to have in the rear. IMO

</div></div>

8&quot; are fine for L60-14-probabaly the optimium tire for it IMO. Also the original Goodyear L60-14/15 and N50/15's were smaller in width and height than the average comparable tire back in the day. Not sure why. I measured a N50/15 Goodyear (nos) at a swap meet and the outside diameter was 25.75 and the used (slightly) Pro Trac N50's I have are 26.25 and the M/T are taller than that.

M/T made the largest L60/14/15 in width and height back in the day and still do.

[Salvatore]

I never ran 8&quot; rims on any L60's that I ever used. Kurt, you are right L60/14's and H70/14's were a mainstay on my nova 40 years ago. I actually like 6&quot; rims for the cheater slicks I use for Day-2.

[Hemicolt]

I'm saying that alot of the people I talk to today, that have Day 2 cars, are running 8 to 10 inch rims with a tire height 27 to 28 inches tall.
Letting air out of them is not an option for street driving.
When I used to build drag cars we would tend to use a rim a little wide on the 10.5 tire cars. This would put the contact patch dead flat on the track.
I see alot of the old 60 series tires at swap meets with the center wore down and the the outer edges look new. This is from running to wide of a tire on a narrow rim.
But to be honest, I can't say what anyone was doing back in the day. I was born in 69..lol

[Schonyenko2]

I ran Goodyear L60 15s on 8in Fentons on my yellow deuce. 14lbs air pressure. Hooked hard at around 4k. Had 7's on the frt.
The Moses deuce had G50 14s on aluminum rims. I thought it was an unusual size for the time period, but maybe not. An N would have dropped the rear to about 4.56 I think. Mo said she was fast. I don't doubt him for a minute.

[Salvatore]

not many of us messed with rims wider than 7-8&quot; back in the late 60's early 70's. Most ran 7&quot; wheels and if they wanted the tire to stick out they would buy the deep dish version for the rear. Many times the center of the tires wore out because of to much air pressure. Even if you buy vintage tires like I do, you will need to drive on them for 50 years before anything wears out. I drive my cars weekly(weather conditions) but only 8-10 miles at a time. Remember, unless these cars we are talking about are time capsules like Mockingbirds Deuce we are really only cloning a Day-2 car today even if we run all vintage parts its still a vintage Day-2 car of 2011. That is why to me, a &quot;real&quot; Day-2 car is priceless and should by any means not to be restored if possible unless ALL the parts that are on that car for the last 40 years gets restored with it. My 69 Z/28 is in Day-2 trim but it is a Day-2 clone of an original 69 Z/28 that was modified in its day. I like 15X6 in the front and 15X7's in the rear. Its up to the individual.

[69 Post Sedan]

Just to be clear, I run my rear tires around 25 psi without any issues on the street. The picture of me at the track was around 17 psi. I should have been around 13.

I thought if you ran a wide tire on a narrow rim the center will wear out in the center? <<GRAEMLIN_URL>>/hmmm.gif

[LeeP]

This is another great discussion. It is springing off a post and recent discussion about a day two look on an Oldsmobile 442.

I will add that since there are no 14 inch 60 series options and the currently available F and L 60X15 you only have a size I would not have bought and huge tire and rim option. I know my car &quot;day two&quot; got a set of 14x7 inch aluminum rims. So for day two correct I currently only have reproduction tire choice of G70X14.

I never ran 70's on the rear of my cars during my muscle car years, always ran 60 series. So I would assume next set of tires after the stock ones wore out would be H60X14 or better which is what I am going with. You probably need two sizes of 14 inch 60 series to satisfy an almost stock look and a oh wow those are big meats look. Lee

[PxTx]

To be honest, I feel comfortable with the current offering of tires for the rear. What I would love to have is new rubber that is a reproduction of these Stahl front runners!

[Hemicolt]

The original question on this thread : Is there a size that is needed for the Day 2 group? Now we know the specs of the F60 and L60-15. The L60 covers the guy wanting 28 inch height and the F60 doesn't. Now, if someone wants to run 15&quot;x 8&quot; rims and wants 28 inch tall tires, the only thing he can run is a L60. This tire has a section width of 12&quot;. This tire is to wide for an 8&quot; or 7&quot; rim. (I'll get back to this in a minute).
The F60 is the required width for the 8&quot; rim but it doesn't have the 28&quot; height that the buyer wants. So this tire is to short in the eyes of the buyer.
If the buyer wanted to run a 10&quot; rim, the L60 will cover his needs, but not for the 8&quot; rim. This is why I made the statement in my 1st two post. Is there is a void here for the tire size the buyer wants? I say yes as of right now. I have not seen a 28&quot; tall, Polyglas tire, etc. that is the proper width for a 8&quot; rim. I'm not saying there is or isn't, I've just not seen one. So this is why I said what I said. I saw a &quot;size that is needed for the Day 2 group&quot;.
The person who wants this size rim and tire may or may not care what is exactly period correct. It's their car and they can put whatever size rim and tire on it that they want. I'm going to put modern, repop Cragar S/S rims on my car. They are made a little different than the &quot;real deal&quot;, but I don't care. The only person I need approval from is myself.

Now about rim width and tire width. You can get a full contact patch with narrower rims and a tire to wide, using a DRAG SLICK. The reason is because a drag slick has soft, flexable side walls and when the car accelerates the tire sidewalls allow the tire to flex enough to put the full width on the ground. The reason alot of 10.5 tire guys tend to run a little wider rim is because those street/strip tires have a stiffer sidewall. The can't flex as much and get the entire patch down.
Street tires are different. They are made for driving on the street. Which means proper air pressure rated for the tire. Not 12 to 15 lbs so the tire can have even contact. That's for racing, we are talking about driving on the street. When you mount a street tire that is too wide for the rim, the sidewalls pull in and the edges of the tire pull up to some degree and they do not have the same pressure per square inch across the contact patch. And the reason the center wears out first? Heat. Heat builds up in the area that has the most pressure per square inch and will wear that part of the tire quicker. There could also be a problem in cornering and wet conditions.

All this doesn't have anything to do with looking dead on correct or driving your car 8 to 10 miles at a time or really anything that has been brought up.
It's got to do with a gap in a tire size being offered, that others and myself like to run. 28&quot; tall tire with a section width of 10&quot; that works good on a 8&quot; rim, so as to have a more even load on the tire. I'm sure that SmallHurst is speaking of existing tire sizes and that's fine, but I do not know for sure if there was ever anything offered that might cover that size being needed by buyers who are wanting that size.

[whitetop]

Chandler, the L60-15 is perfect for an 8&quot; (steel)-8.5&quot; (aluminum) rim.

I think a 7&quot; rim is too small for an L60 tire. A 10&quot; rim on L60-15 is pushing it but passes. You don't go by section width but tread width when matching tires to rims. You want the tread to be no more than 2&quot; greater than rim width and with most L60's at 9.75 -10&quot; tread width that is ok for a 8&quot; rim..

Every original spec I have ever seen on L60's is they are for 8-10&quot; rims.


M/T L60-15 with 15 x 8.5 Ansens. Looks pretty good.

http://i1116.photobucket.com/albums/k572/OGCPICS/philsduster.jpg

[whitetop]

Cragar 15 x10 on L60-15. Not the greatest match to me..the part of the tire attached to the rim is wider/sticking out further than the top of the tire. Check out the tire in the top picture were it meets the road. The tire is wider near the rim than the tread so it bulges out.

http://i1116.photobucket.com/albums/k572/OGCPICS/columbocamaro.jpg

[Salvatore]

And my last sentence was &quot;its up to the individual&quot; I like 7's cause they don't stick out or rub. Was never really worried about the footprint. All good points fellows.

[Hemicolt]

Actually if you do it correctly, you go by section and tread width. I learned this by going to tire seminars and learning from chassis builders who knew what they are talking about. And there was plenty of info about street tires.
Here again, some peoples first priority isn't looks. They want their tires to have an even contact patch on the road. Here is a 255/70/15, which has the measurements I spoke about. Around 28&quot;tall, 8.5&quot; of tread and a section width of 10.25&quot;. It is mounted on a 8&quot; rim. The tire has a nice bulge on the side wall and has dead flat wear pattern and looks right. A L60 with a 12&quot; to 12.25&quot; section width is 2&quot; wider than this tire. To wide for this 8&quot; rim. This is my priority because I put more than 8000 miles a year on my car.
Another example, a 235/60/15 mounted on a 8&quot; rim. You can see a bulge on the side wall and flat contact patch. This tire also has a section width of 9.75&quot; to 10&quot;, not 12&quot;. Looks good and flat tread. This is priority for Todd because he is going to put 1000's of miles a year on this car.
I really can't tell from the side view, but the top picture of the Camaro looks like the center of the tire is raised higher than the edges. I can't tell on the Mopar, but I think it looks good from the side. But I wouldn't pass any kind of judgment until I could see the contact patch.
If the Camaro in the bottom picture has a flat contact patch, the tread is 9&quot;, the rim is a 10&quot; and the section width is 12&quot; to 12.25&quot;, I can go with that. But that's me. I like proper function 1st and looks 2nd.
None of this really means any of us is right or wrong. To the appearence first people, they are right because they like the way it looks and that's all that matters.
To the function first people, they are right because they want proper wear pattern and that's all that matters.
To the purist people, they are right because they ran 7&quot; rims back in the day and that's all that matters to them.
The man asked if anyone thought there was a tire size needed. I gave him my answer. Around 28&quot; tall, 10&quot; section, 8.5 tread and that's all that matters to me.

[whitetop]

Chandler, back in the day we did not have all the tire choices we have today. If you want a specific tire imprint on your car you might not get it with vintage bias tires and might have to use a modern radial tire.

Basically all you had back in the day if you wanted a larger size tire in terms of width was F60, G60 and L60's-there was nothing made in between those two sizes unless you went to the 50 series but then you loose height. Our tire choices back then then kinda reminds me of the old Wendy's commercial on Russian &quot;evening wear and swim wear&quot;..the older guys will remember that commercial.

Just as in limited tire back then, wheels were also very limited. you had two offsets back in the day, stock and deep dish(reversed) in custom wheels and this is if you were lucky. Many aluminum wheels such as slots just came in one offset. An American or Ansen 15 x 8.5 slot for instance just came in one offset back then-deep dish. That is why shackles and air shocks came about. Today you can get any offset you want from each wheel available..some wheels have 5-8 different offsets available.

Sammy is right, the 6 &amp; 7&quot; rims were common in the late 60's and early 70's due to the fact street tire choices in larger widths were extremely limited. Guys who wanted something wider went with mostly slicks or cheater slicks or super wide Indy car race tires. The L60 series tires were not released until 1971.

Pos-A- Traction also had some wider street tires in the late 60's in a larger width based upon the tall L70-14/15 tire core. I think the tread width was around 8&quot;

[Hemicolt]

Thanks for the info. That was part of my original comment / question, I wasn't sure if anything was ever offered that filled the void I was speaking of.
Pro Tracs can almost cover the look that some people are wanting, but Polyglas tires in that size would be really cool if it was possible.
And as I said above, I understand what you guys are saying about what was being offered back then and what everyone may have liked. But that was then and this is now. There is a wider offering of wheel sizes and offsets. It's kind of like camshafts. I never hear about anyone asking for a 3/4 or full race cam. They are taking advantage of a better suited variety, just like some using a different wheel size today.
If I ever went to bias ply tires on the Chevelle and wanted a 28&quot; tall tire, I would install a L60 on a little wider rim and mini tub the car. The tire I have on there now is the widest I can go without anything rubbing. It wouldn't have anything to do with being 100% period correct, it has to do with me having my car look and sit the way that I want it to.
My Vega may or may not have some little things here and there that may make someone say, &quot;that part doesn't have the look of a real Day 2 car&quot;. That label or name doesn't matter to me. Me being happy with my car is what matters. I use the term on here because everyone knows what I am referring to when I say it.
And even though I ask questions about the history or request the valuable opinion from someone, the final choice is my own.
It's like my Model A I'm building. The street rod, gasser and beater crowd all argue with me about what I am building. Some say it is more of a street rod while others argue that it's not. I don't care about being placed in one of their cubby holes, I just care about building what I like. Which is what hot rodding is supposed to be. Expressing your own taste.

Now,shouldn't we get off this side road we went down and get back to the original question? Someone else needs to suggest if any tires should be covered..lol

[whitetop]

This tire thread is like pornography. We can't define the look that all can agree on but know it when we see it. LOL. <<GRAEMLIN_URL>>/smile.gif

[Hemicolt]

LOL!
I don't know. There seems to be one view that all men can agree on when it comes to that subject.

[69 Post Sedan]

I personally like this thread....different ideas/opinions.

Back to the OP. I think 14&quot; tires would be a hit; G60-14, L60-14's, F70-14, G70-14 etc...

The reason I say this is that it appears 15&quot; tires are readily available....even vintage ones.

Kurt

[SmallHurst]

If you are wanting a taller tire, but are willing to give up a little footprint, the G70-15 is available. Some guys who want a more level look go L60-15 in back with a F70-15 up front.

From what I am gathering, it sounds like a G60-14 or L60-14 would be a good offering to look at? The question of the day would then be how many would purchase this tire?

I would go with L60-14 than G60. G60-14 were kinda small and I would think would have a limited following out there.

[PxTx]

You see, from where I am standing, although I have several vintage 14&quot; wheels, I am more likely to buy tires for my 15x4 wheels first. I would think a set of 7.60 or 7.10 15 would be a popular tire. It would be a real hot seller if you could get the Stahl name on it. Without that, i would probably not be as interested.

As for the L60-14, I think I'll hold off for a while.

Here's the original owner's set of 1970 15x7 Cragars with the 1971 Parnelli Jones L60x15s in the rear and the 15x4 with F78x15 in the front. They are both 27&quot; tall.

Great thing about those B-Body Mopars is that there is still 1-1/2&quot; of clearance to the wheel well trim.

[Hemicolt]

Very good point. What are the choices on front runner tires these days? Pro Trac 560-15 or 215/75/15 and standard type bias ply tires from Coker. Not sure of anything else. A Stahl tire would be a huge seller, IMO.

Firestone Drag 500 7.10-15 &amp; 7.60-15 would be off the charts. Without a doubt the #1 front runner from the late 60's/early 70's. There were rumors this tire was going to be done from original molds but nothing so far. I'm not going to hold my breath.

[SmallHurst]

As for a Stahl tire.... I can speak with a certain amount of authority that it will not be coming from Kelsey.

Kelsey has a 7.60-15 blackwall or a whitewall Custom Super Cushion bias,not Polyglas or Speedway wide treads.

A 7.10-15 is also available whitewall only.

[PxTx]

I'm sorry to hear that. The Firestones would be cool too.

Anyone suggest a way to re-create these older tires look? I've seen lettering sanded down. I think I've also seen a transfer paper where you could create a logo and then rug it to transfer over on the tire. Its been about 12-15 years since I've seen it. Anyone care to coment?
