I have 37x13.50x17 Toyo MT. with 2.5" spacer front and .75" rear. These tires knocked the rear fender off when flexing. The tires before did great with only a small amount of rubbing. (Ironman 37x12.5) The Toyo's are much Taller (1"+) and much wider (2"+). I did the fender chop and now full flex...
