Continental Gator Hardshell Road Tire. First there was GatorSkin, a remarkably durable tire in its own right. Then came Ultra GatorSkin. Now, Continental takes durability beyond the limits with the GatorHardshell Road Tire. Like the Ultra GatorSkin, the Gator HardShell tire balances great ride characteristics with long life and at an affordable price. The Continental GatorHardshell road tire features the bead to bead protection of DuraSkin, PLUS a Hardshell casing and extra wide PolyX breaker. The result is a super durable road tire that's about as puncture resistant as a tire can get.
