This was my first paddle tire and I bought another one. The first one was too big for my back-up bike (89 KDX200). However, I simply powered/scraped through and after about 30 minutes it worked fine. Better than fine...I was a hill climbing machine. Horrible in mud but I ended up using it everywhere and it gave me much more power. I put my second one on my KX500 and as you can imagine...braaap. I use the Sandy 4 for all around riding but if you are a dune rider it isn't fun without a paddle tire.
