Hello all. I need a little help with tires sizes. I've researched the hell out of this and I am still not sure. CTS-V coupe stock wheels, what's the biggest tires you can run front and rear? During my research I've found folks reporting the super sports run wide so a 305 might bulge hence the nature of my question. Would 295 be a better choice here? I want the tire flush with the fender but definitely want to go wider than stock. Forgot to add that I don't track the car, just normal spirited driving. I want a more aggressive look and obviously better traction and handling.

I am also considering going with Rohana RC8 20" or RC5 19" wheels but I haven't made that decision. I am sure that will open me up to additional tire sizes. But for now I want to focus on the stock wheels. Thanks!

I would do the 295/35 on the rear and call it a day...

 

[cyclops24]

265 front?

 

[thebigjimsho]

Either that or the 255s...

Another vote here for 255/295. I also wouldn't run Rohana wheels as they're heavy beasts. TSW's will save you 4 to 5 lbs a wheel and you can run 9.5" fronts and 10.5" rears.

Thanks for the heads up!! Someone else had mentioned to me that I need to take into consideration living in Pittsburgh and dealing with potholes. They said I should get something strong, possibly forged over cast to prevent wheel bending. I actually like the TSW Tanakas and looked at those before. If I got with TSWs, I assume I can run a wider tire since the wheels are wider than the stockers?

I appreciate all the help. This would be the first time I purchased after market wheels so as far as offsets, sizes etc I am a dummy. I figure once I know what I want, I can call a wheel place and tell them how I want them to look and they'll set me up correctly but before doing that I like to be educated and not just take someone's word for it trying to sell me something.

You have to know more than the salesman. If you are working with a reputable shop then you should be in good hands, but you are right in getting an education first.

There ain't jack you can do about those craters! Nothing. I was actually just there and quickly reminded myself how spoiled I am down here.

I went with TSW Nurburgrings as they were light, strong and relatively cheap due to the rotary forging. Interlagos are another choice and they've added at least 2 more rotary forged options recently. The coupe fitment size is:

Front - 19x9.5", 41 offset, 5x120 bolt pattern

Rear - 19x10.5", 27 offset, 5x120 bolt pattern
