Yesterday while in the California desert, put 2 inch gash in my sidewall on a front stock tire. Put on spare, got back to camp and saw that dealer sold me a 12 inch wheel as my spare. Even though it fit, it was rubbing on the Brake line. So my questions are: What inexpensive 14 inch wheel to use for spare? Have any of you gone to 26 x 11 x 14 all the way around for tires? What tires are best for rocky hard terrain?
