Thanks to Quentin's advice, I bought this CST c755 tire. I'm absolutely thrilled with it! The grip is fantastic, and the traction in the rough stuff is incredible. It's truly the best tire I've ridden on my Sur-Ron in 18 inches. You can tell the products are tested and approved by MTO, which is a huge plus! It's way better than my big Michelin 100/100 18. Much lighter and ultimately the same size as a 100/100 with cut-down knobs for chain clearance. I highly recommend this product!
