Default Max Rear B/S & Tire Size 68 Camaro

Looking for some advice on fitting L60-15 or possible N50-15's on my 68 with Centerline Auto Drags. I'd love to stuff some fatties on the back with skinnies up front for street cruising but really need to figure out what the maximum backspacing is running an 8.5" rear wheel or possibly a 10" w/o them sticking out too far? Will the 8" or 10" work with 4.875" backspace or will they hit the springs?

Anyone run 15x10 rears with N50's?

That's definitely the look Mark.

Now if I can just figure out the backspacing that'll work with those old Lakewood J-Bars like that and put a set together with some Pro Tracs I'll be set? I have the same bars but need to figure out the wheels and i'm good to go here.

NorCam, here are the specs from the article, and a link to the original article about that Camaro:

Wheels/Tires: This is where some folks just don’t get it. Cragar S/S wheels that protrude past the quarters are out of style, but they are absolutely perfect for this car. The fronts are 15×4.5, while the rears come in at 15×10 inches with 4.5 inches of backspacing. When you consider the 26×7.5- and 28×12.50-inch Mickey Thompson rubber, this combination would’ve been a car guy’s dream in the early ’70s.

Mark the rear Cragars in the photo are 3.75 BS not 4.50. Ratpack, Troy C built the car. Never take what Hot Rod says as accurate. They just wrote an article saying the first CC Street machine Nat's was 1977 when in fact it was 1972.

You cannot run 4.50 BS 10" Cragars with N-50 size tires on a Camaro as it will rub the springs-you can 10" with 4.50 BS with L60's though (P275-60-15). You can also run N50's on a Camaro with 8" wheel deep dish 2.50BS

Good info and I do appreciate your input Whitetop.

I'm just out in the shop today tearing into my 68 to convert the drive train to a hotrod setup. Just finished saving the original style exhaust and was looking at wheel/tire clearances under there while it's on the rack. Looks like the 275/60's on the 8" Torque Thrusts have an inch clearance to the shock mounts and good clearance back towards the springs but then I looked up in the wheel house to see they have rubbed a couple times up high on the inner wheel tub. If I go any deeper to the inside they're gonna rub more unless I stiffen up the back suspension a ton. (not thinking of doing that)

If I add 8.5 Centerline rims out back and maybe I can fit them with L60's mounted up. Centerline 8.5" come with 3.315 BS if I remember right. I'm thinking those would allow enough clearance while the L60's wouldn't have too much sidewall projection off the rim? I'll measure the B/S on the current rims later tonight. Getting ready to pull the motor this afternoon and ready to unbutton the motor right after lunch here. More when I have measured the current rims to see what they have for backspace.

HRM's '67 Camaro had N50s and Centerlines for a few years. 15x10s with 4 7/8 backspacing and 1 1/4in spacers.

I remember that car. Centerline has a 3-5/16" BS or 4-7/8" BS. I guess they used what they acquired for that car and then added the spacers to get them to fit the car. I have been trying to order wheels the past couple days but I'm finding Summit and Jegs don't have much in stock and wheels are on back order from Centerline. I'm still debating those versus Cragars and still hunting for just the right combo with tires.

In the interim, Motor was pulled and torn apart last night while getting the new motor and a new M22 ready to go into the car. Still like the Torque Thrust wheels and will use them when I need to put some highway miles on it, but for street cruising I'd like to fit some new wheels with bigger bias ply tires for that menacing look.

I think that Born 40 years late has L60's on his Copo. Give me a ring, I can set you up with L60 Polyglas.
