This 20x6x10 set I'm selling will work on your stock rims if you spend time at the mx track: 2 Pair 20x6x10 Kenda Klaw MXF Front ATV Tires 4 Ply K532 Radial | eBay . If you spend a lot of time riding over rocks you may want to up-size to a 21x7x10 or a 22x7x10. Smaller tires improve handling while larger tires improve ground clearance. Light tires like a 2 ply also improve performance but give up some durability to heavier tires like a 6 ply.
