Need some input. I have 02 prairie 650 and need new tires. I do lots of trail riding with some mudding and rocks. I still have stock tires. I'm going to Utah to ride the paute trail in july. so I have to get new tires. I have been looking at swamp lites and swamp foxes. The both look like good tires. The other problem I'm having is 25" or 26" I ride loaded down with camping gear and stuff so I don't want to loose much power. The 26" tires have deeper tread and I can get wider rear tires. Would the 26" swamp foxes with 1.2" deep tread ride rough or bite to much and put lots of stress on drivetrain? thanks any input would help.
