Revisiting this thread...
After a full summer of use and abuse, these tires have held up beautifully! I had all the grip I needed in the woods, on grass, on dirt, and of course, pavement. They sling mud everywhere and make a mess, but what is mudding without being covered?!
I would HIGHLY recommend these to anyone with a stock height cart looking for cheap, good quality traction tires. Not only do they enhance the look of your cart, they add to your off-road fun-ability! Great for tearing up that unwanted lawn as well...
