I've got a 2008 Grand Prix with the standard 225/60/16 tires and rims. I found some GXP tires and rims 255/45-18 front, 225/50-18 rear
Will they fit ok on my base Grand Prix? Just wondering if the GXP front end components are designed specifically to accommodate those bigger tires and wheels or if my base GP can handle them? I would really like to get the GXP rims but not if they are going to cause me steering problems etc

Thank you!
