I'd like to put some 15" wheels and 30" tires on my 1100 Sand Viper. I want to get more ground clearance. I have already raised the shock mounts as high as the heim joints would allow. Only got about 1 1/2". It now has 27x11x12's on the rear. I'm thinking 30x9.5x15 on the rear and some narrower 30's on the front. My riding is strictly desert, some sand and rocks, no mud. My concern is, will the drive shafts on the Viper handle the 30's OK. I don't know if there will be more stress on the shafts. They seem pretty stout. I run it pretty hard and have had no trouble. Appreciate your thoughts.
