I have an 06 gxp.. now the front tires are bigger then the back factory I'm sure you guys may know, on the newer models are all four tires the same size on the gxp? also if I put all same size tires on the car will it affect the car at all?? I'd really like to buy all four of the same size tire and be able to rotate them so that they last longer.
 


All gxp's had the same size wheels and tires. There are many using the 18x8's all around with no issues.
 
are the 18x8 alcoas the rims in the back? are the rims in the front bigger or wider then the back ones? is that why the front tires are bigger? or are the rims the same but the tire is widder?
 


If I remember correctly, its 18x8 up front and 18x7 in the rear. Pontiac did that to supposedly help handling. I myself think its stupid. As others said, get tow more 18x8's and run the 245/45/18's all around.
