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 isnt always better, but in this case MORE is exactly what you get.
