ok guys i have a 95 gt. the guy i bought it from had the 2000 chrome cobra r wheels on it. love the look. he has michelin pilot sports on it. front are 265/35/18. rear are 285/35/18. my question is i know on the front i can go up to a 275/35/18 without any worries. but how wide can i go on back without having to adjust anything. i was looking at either 295/35/18 or 305/35/18. the car is a nice summer cruise car and once the motor is back together its going to be driven only on summer car cruise nights or weekends. so tires will last me a long time and im not to worried about drag strips or racing. so any input will be appreciated. thanks guys.
