if you go to a hardware store like loews you can get new rear tires well id use them for the rear go to like the lawn mower section and look for the front tires of a ride on lawnmower they have a nice squared look but not like good offroad tread or go to yahoo.com google whatever and search snowblower tires and you can get holeshot lookalikes made for snowblowers but will fit your stock sunl rims

 

Tires for the Sunls at Lowes huh?.... ok....
