Many guys with late 70s TA's and the 15x8 WS6 wheels say you can run the 255/60/15 tire on the front with no rubbing of the inner fender wells.

This tire is slightly shorter and wider than the original 225/70/15 on those cars.

But what about the early 70's TA's? I would like to run this size all around on my 70 TA, which is lowered 1" in the front, on a 15x8 wheel.

The 235/60/15 is approximately the same size as the original F60-15 on our cars.

Are our fender wells the same size as the late 70s cars? Thanks!

Rub on sway bar at full lock perhaps, adjust accordingly if an issue.

Running a set of 265/50/15 Radial T/As (old) on my 73's front end on 8 inch wide 15's.

Bummer Goodrich dropped the 50 series 265 and no 255's either


Zero offset wheels.

I have a set of the 15 X 8 snowflakes without tires- can't do it right now but will try and update when i get some new tires mounted up on them in the future.

fender wells, fenders & suspension are basically the same on early cars... i have used 255/60 on the front & rear of my 72 firebird that is lowered 1.5" in front & about the same in the rear with no rubbing issues using 15x7 rally2 wheels.

for a short time when the car was first being driven after a engine & driveline restore i had 15x8 snowflakes with 255/60 front & 275/60 rear... no issues at all for normal driving, it may be possible that at full lock of the wheel & backing up on an angle there could be a slight rub in the front but that is very rare & usually on cars with sagging front springs lower than a good stiff lowering spring.... but ive never had that happen. you should be fine 99% of the time with 255/60s all around.

I haven't run that size on the early cars, but I've had several 77-81 T/As with 255/60s on all 4 corners and they fit great and look awesome.

My old 1971 Trans Am with factory springs. The honeycomb wheels had 255-60-15 tires and the tires did not rub. The rally II wheels (KR code) had F-60-15 tires.

[71GP76TA]

245's look and fit better IMWO.

[SD73]

I run 255/60/15s on all 4 corners of my '73. On rare lock-to-lock occasions I'll get a slight rub. They're on the factory rally 15x7s.

[eaglesan13]

I agree, I'm running 245's on my Formula. .

I had them on my 73 with 15x7 R2's for a while with same results.
(A/C car)

and then also 275/60/15 on 15x7 mid-80's TA alloys , on my 79 for a while (set of 4) with same results.

275/60 up front? thats a awfully big tire for the front & will rub a lot easier on most stock height or lowered cars. got any pics of the car with 275's?

[Baron Von Zeppelin]

I don't have any pictures of the 79 with the later model wheels on it & the 275's.
Just some older pics when it still had the 15x8 Snows on it.
4spd 4WDisc Loaded
My youngest brother bought it from me and still has it.
Can check sometime with him for pics of it with the 275's.
They were on it when i sold him the car.
I thought they looked good on that car too.
Bought those tires (Goodyear Eagle ST) "as like new" on the cheap via local trading post - they were on a pick up truck a guy had just bought and he wanted dual purpose tires on the truck.

The 73 was my SD.
It had 255/60 Gyear Eagle GT when i got it - when it needed new tires i bought new Eagle ST 245/60 . And almost didn't like the 245 look versus the old 255's.
Took a couple weeks to get over that hump.

This was all back when i drove those cars on a regular basis in 80's early 90's.

That Formula made me drool all over my keyboard..

If it helps this is my 79 (with 77 fascia) and 275/40 17’s all the way around

[Aus78Formula]

One reason I prefer staggered with the wider front track and wheelarches. Still looks great obviously!

275/40s are only 25.7" tall.. 255/60 are 27" tall.

[71GP76TA]

Years ago I had 255's on a '79 10th anniv... no rubbing..

[napster]

I run 255/60's all around my '73 on 15 x 7. No rubbing.

I had run 255/60s on my'70 and had some rubbing issues on the front. Went to 245/60 on the front and the problem was solved.
