Would these look nice on a 91 Camaro and/or would it fit without a problem?

 

That setup you have will work.
My GTA has 18x8.5 rims with a 235/40/18.

 

shouldn't have any problems with them and should look pretty damn sweet

 

Axe the whole 7.5 width and at least go to an 8. I had some 17x7.5 and they look stupid from the back! You have this wide a$$ car and then you get behind it and there are these skinny looking tires! I loved the wheels I had on there but it bugged the crap out of me so I switched to 17x9.5's!


Those were the wheels I used to have on it in the picture

 

ya go at least 8's if not 9's. Id like to go 18X9 all around when i do my car but due to the rims im choosing to go with i may be forced to go with 18X10 out back and 18X8 up front. 18X10's out back will look awesome.

 

that gta needs a serious drop (at least 2inch) ASAP!

 

not the right tire choice....

8's are great for the front but at least a 9-10 rear will look killer. that is if your lowering the car. if not go 9-9.5 all around.
