Just bought a 450 the other day and it came with two sets of tt tires and wheels. i am keeping one set and going to sell the other. The ones for sale are American Racer SD33 18x6x10 fronts on douglas red label wheels and 18x10x10 rears on douglas red label wheels. I was told by a friend that they are a medium compound and in great shape. Would like to get $300 for the set of 4 tires on wheels. dont want to ship but can if buyer pays extra for shipping. can meet part way for delivery if within 60 miles of Nixa, MO. I can get pics if needed.
