What are the largest tires that I can fit on my 17" stock wheels without having rubbing problems? Currently I have 245/45R17 on and would like to upgrade to a larger tire without purchasing new wheels.

thanks for the responses.

I think most people just put on wider tires on the rear...they are 275/40/17 I believe..Nitto 555s. Those apparently will fit on the stock wheels....the other brands from what people have said on here require wider wheels.

If I go with a 265 rear tire, should I go with a 40 or 45 aspect ratio? I imagine if others are getting 275's on 265's should fit without rolling the fenders, right?
what size rim you got?

245s are the widest you can fit on the stock 8" wide rims. Go to http://www.tirerack.com and look for the tire sizes you want. Click on a tire and it will give you rim sizes that will work.

The car already understeers in the stock set-up. Even though larger tires in the rear will improve tractions turing acceleration, won't they make the car understeer even more?

Could you get away with 265/40 17 on the front and rear? I want to be able to rotate my tires regularly. Guys running the DR's, are you just putting them on the back and not the front? I kinda want the car to be symetrical.

Understeer is a function of the front tires not having enough traction. The front tires skid forward through the turn instead of gripping and turning like they should. I suspect the car would be much more prone to oversteer if it had proper tires on it to begin with. The all-season tires that pontiac puts on there kinda suck. The traction is horrible when they are cold, and only slightly better once they get warm.
