The SUPER Gator. The Ultra Gatorskin has set the bar for a perfectly-balanced blend of ride quality and long-term durability without breaking the bank.but still the roads of North America demand a model even tougher. The all NEW Gator Hardshell delivers!!! Sharing the bead-to-bead protection of DuraSkin, the Hardshell casing wraps further into the sidewall and an extra-wide Poly-X breaker covers the entire tread strip from shoulder-to-shoulder. Added material in the tread strip not only improves mileage, but lends yet another degree of puncture resistance. More isn't always better, but in this case MORE is exactly what you get.
