Bought 2 new 420 fourtrax and went for our first ride together without kids this Friday and had a blast. Wife"s idea for our 12 th wedding anniversary (I am a very lucky boy) had babysitter and hit the trails. I have been wanting to upgrade the tire for a while and wife was not thrilled. Long story short she punctured a tire, went flat on trailer. Now we are upgrading. Dealerships is recommending swamp lites, riding in Calgary in the foothills, mud, rocks, dirt. I was originally thinking Mud lite from my research. Going with 25" on stock rims. Do the swamp lites wear faster? Any one riding these tire any recommendations? Also thinking of maybe running 2 different sets on each quad. Thanks.
