Early production ZR1's (90-91) were equipped with the Goodyear "Gatorback" radial tire. In '92, the Corvette sported new shoes from the Goodyear corporation, namely the GSC radial which it used throughout the duration of ZR1 production. The GSC is a much quieter, much softer feeling tire and is highly preferred in most instances over the Gatorback tire. In addition, the GSC easily outperforms the Gator tire in most every category of aggressive driving situations.

One of the few problems we've encountered with respect to wheels is the cracking of the '90 model wheel when used in aggressive track conditions, especially when used with traction enhancing tires. The cracks seem to be more noticeable from the inside of the spokes. It is highly recommended that all wheels be thoroughly inspected before and after use in severe traction conditions or before any high speed operations.
