Talked with Doc, from TireRack. XL, is same as RF, they are both reinforced, which we need. Problem is, 235/35/19 is not safe for the S4s because of the front weight. That size falls short of 44lbs. The 245/35/19 exceeds it by 110lbs. I went ahead and changed my order from 235/35/19 Fuzion ZRi to 245/35/19 ZRi. The tread width is only 8.5", and it still has a nice curve on the shoulder to clear the fender. My current Falken 452 tires have a tread width of 9.1" That's an extra .6" less tread width, before it starts curving down toward the sidewalls. Here's a pic of my old car and what they looked like. It has a nice stretch, naturally and allows for fender clearance.
