I know some here have changed tires do have to put on as a set like a 4x4 truck? My book says this limted slip front end sense,s the rear slipping then the front kick in, My Deal is! tried to put my track on from a 94 machine onto a 2006 and All dealers said should work, But! it is to short by about 3in. even with letting all the air out of tire. Only thing i can think of is that older machine has small tires on it? There at my cabin didn,t bring them back in. good excuss for another trip! Can i get away with the back four, or would that start grinding up that new style front end?With them being smaller if that is the case. Any Thoughts on this?
