Had these installed on a 2WD compact tractor. Very pleased with the traction. These are so much better than the factory turf tires. I can drive with more confidence on dry ground and even wet ground during the spring thaw. They seem very stiff for only 4 ply. Even though they are the exact same size as the turf tires that I replaced, they are actually smaller. This changes the speed of the tractor. It also gives more space around the fenders and makes the tractor sit lower in the rear. In my opinion all 29-12.5-15 tires should be the same size. That's the only slight negative for me.
