I have 2010 gt premium with stock 19" × 8.5 wheels. I'm getting ready to replace 245 45 19 tires but not sure what to get. Does anyone have recommendations for tire size?

 

I am not sure you can go to much wider with a 8.5 inch wheel. My son is looking at a 2013 with the optional 19 x 8.5 and he is going to have to buy wider wheels. Most tires company's have a suggested wheel with in the specs.

 

I'll try looking at specs. I appreciate it

 

Not sure where I got this, but according to the calculator the max width you can go with 8.5" wide wheels is a 255/XX/XX
