What is the biggest tire you have ran in an a body, before tubbing it (a bfg to the wheel wells dont count as tubbing.).

Im running 275/60r15 on a 8inch rim. No.rubbing

 

Anything more than what you are running now will require trimming the wheel lip and the right offset wheels. That is what it took on my 70.

 

You can run a 10 inch rim with no rubbing.

 

I ran a 10 in rim but you have to watch the offset, I had to trim my outer wheel lip to get them not to rub on the 295 50s I used to run.
I am talking about 10s on the rear of the car. No way on the front. I ran an 255 60 15 on the front on a 8 inch It was close and would hit on a bump at full lock.

 

I run the same tire and rub the Hotchkis anti sway bar on the front. WAY big! Otherwise I like your setup too. It's not like I'm going to change them.

 

Yeah ive got that sickness that makes you want a fatter tire no matter how big it is. Lol im looking at 295/50r15

 

i run 275 60 15's bfgs on 15x7 olds rallye whells with a ton of space i ran 275 50 15 on 15x10 wheels with stock back spacing for a very shorth while they ran even with the wheel lip no rubbing you should be able to run a 295 with the right offset go one inch towards the inside and 2 out the tires sould sit about even with the wheel lip you could go two inches in but i dont know if the tire would rub with my 275's i got an easy 3.5 inches or close to it between the tire and the wheelwell

 

Tis a lie I tell you! I have 295/50/15's on an 8" rim on my car right now...when I get new rims I'll be putting 325/40/15's on it. When you measure everything correctly, you'd be surprised what you can fit on these cars.

 

Lol thats what i like to hear pilot, my thing is, if it rubs. .. Thats why god made the hammer :-)
