Its time to get new tires and I am thinking about getting a wider tire. My current tire size is 225/45/18 and I wheels are 18x9.75 +20 offset. I want to run 245/40/18 so I'm not running them as stretched. My fenders are going to be rolled once I get the tires, my concern is rubbing on the inside, hitting the rear strut. I am lowered on H&R springs. They currently rub now when I have people in the backseat. Would I be able to clear 245/40? Would adjustable trailing arms help?
