Hi. I have a 2011 G37X Coupe with the sport package which includes 19" x 8.5" factory wheels. Has anyone tried running 245/40R19's on all 4 corners? I know they will fit on the rear as the IPL used 245/40R19's on the rear and 225/45R19's on the front. Stock for my car is 225/45R19's on all 4 corners and I would like to go wider and keep all 4 tires the same due to the AWD of the X model. Looks like I am going to go with Michelin Pilot Sport 4S tires and any feedback from those that have tried them would be appreciated. Thanks Rob

 

Many folks run that size in the front, such as me.
