View Full Version : Skinny front tires

I bought a pair of US Royal 670-15 tires for my skinny Cragars thinking they'd be 27.5" tall like it says on Coker's website. They're more like 28+, which I think is too much for a Nova, so now I'm looking at 560-15 tires. Which would be more period correct for 70-72, US Royal or Pro-Trac? I like the pie crust of the US Royals, but the Pro-Trac for sure looks excellent on Cragars.

I tried the 5.60.15's on my little grey 70 last spring and found they were just too short. Really looked too small IMO. I later went with the 6.40.15 Firestones and think I nailed the look with the Cragar's and 640's on it prior to selling the car. I didn't like the big rubber cut on the inside profile of the Pro Trac either. Here are the Coker Firestones.

I think the Pro Tracs are too short on my Camaro. I'm wanting something a little taller.

Does anyone have an actual diameter or circumference measurement of the 560-15 Pro-Tracs?

Grump had to have bigger than 560-15 on his 68 Nova

bbbenny somehow managed to fit 710-15 on his race car

NorCam, that looks good. Those are supposed to be 27.3" tall. Did you ever measure them?

Reported at 27.01 tall.

I didn't measure them but they fit the wheel openings really nicely I thought. I added some Pro Trac 275/60 rears just before it sold. That balanced out the look as the front sat just a touch high on this car. Always did.

I have a brand new set of 5.60-15 Pro-Tracs never mounted. They measure 25.5" tall with no wheel in them.

Hmm, ground clearance would be tight with only 25.5" of front tire. Might look a little short too.

Here's the look on my 1969 Camaro. These are a borrowed set....I liked the look so bought a pair. FWIW my front springs are not stock.

I am not sure why some pics come out rotated (sometimes up side down)
Try this:

It looks better horizontal.


I measured one of my 670-15 US Royals (not mounted), and it's 89" circumference. That's 28.33" tall!!!

My 640-15 BF Goodrich Silvertown's fit well on my 69 camaro and should also on the nova.

Sorry I wasn’t very clear.....the front 15x4 cragars have 5.60-15 tires. Based on the look, I ordered the same size in a ProTrac. The 25.5” OD is a measurement from my ProTrac 5.60-15 tire

OK, gotcha. Thanks for clarifying.

Pete if u should decide to get rid of your tires I’d be interested and I’m also in Michigan.

I don't think I have any use for skinnies that tall and it's too late to return them, so I'm sure we can work something out. I have a friend downriver I might visit around Christmas time, so we might could arrange things so we can skip the shipping costs.

Did you sell the car?

Car was sold to a site member and has gone back to the USA.
