You can put 245s on all 4 corners if your wheel offset is ET11 or less. By doing this, you will learn all about tramlining too. The steering behavior becomes VERY sketchy with wide tires up front. 225/50/16 is ideal up front. Wide tires in the back aren't such a concern, especially if you do not rotate tires. People on this group have put up to 275s on the back. Chris '85 635 225/50/16 front 245/45/16 rear
