Unfortunately these machines don't have all the adjustments that our family vehicles have. Upper and lower ball jints are fixed so camber is not adjustable. Adjusting toe may help a little, but it is just the nature of the beast. These tires are soft so rolling on the rim is commin causing the edges to wear. Riding on pavement makes them wear faster. These tires are designed to run offroad which really means soft soil or sand to get the best wear. Depending on what surface you ride on most, you can buy tires to match those conditions. Also keep in mind the original tires that come on these machines are not top of the line tires, so you cant expect bargain tires to give the best wear, just like your family car.
