Ok so the tire company is Cheng Shin Tire and the size is 20x10-8. According to http://specialtytirestore.com/c_769.htm they are available in 2 and 4 ply. Wait Load for the 2 ply is 750lbs and for the 4 ply 1190lbs. It also says they are great for minimal turf damage. Price wise they seem to be about $45 to $50. Let me know if you find them anywhere else cheaper online. Hope that helps.
