Sumitomo built the HTR Z5 as an ultra-high-performance tire for tuned cars along with sporty compacts, coupes and sedans. Its stiff tread design keeps the tire stable and grippy as speeds climb.
Broad shoulders place extra rubber on the pavement, sharpening handling and helping the tread wear more evenly.
In the P255/40R19 size, this tire has a 100Y load and speed rating with extra load (XL) construction. Specs include 10/32-inch tread depth, a 50 psi maximum inflation pressure, a UTQG rating of 320AAA and an overall diameter of about 27.05 inches.
