I'm going to order a set of original Bighorns. Should I go with 25x8x12 and 25x10x12 or 27x9x12 at all four corners? Is the extra 1" of chassis clearance with the 27's worth the extra weight? Will I notice loss of power if I go with the larger tire? I have the orange spring and a JBS sheave with 16gr weights---will I need to swap weights with larger tires? I had planned on 26x9 all around but they are on national backorder until late Dec and I can't ride until I get new tires. Another option is 26x12 all around but that seems like way to much tire for the front.
