The General G-MAX RS is a dynamic, summer ultra-high-performance tire for passenger cars and crossovers that's the preferred tire of Petty's Garage. Offering drivers strong performance and long-lasting tread life, the G-MAX RS utilizes General's Replacement Tire Monitor which features letters in the tread that wear off to read "REPLACE TIRE" when the tire wears to 2/32 of tread depth, indicating a tire change is needed.
