Looking for some opinions, my plan was to buy Toyo open country AT 3’s in stock size 275/55/20 so I didn’t have to mess with recalibrating my speedo. I just realized that tire is an XL in that size. How rough will an XL tire ride compared to SL? Am I better off going to a 275/60/20 which is an SL and recalibrate my speedo.
