Toyo Proxes Sport Tire 275/40ZR18 99Y

The Toyo Proxes Sport is a max-performance summer tire and the flagship of the Proxes line, made for modern sports cars and luxury sedans; Toyo's fitment examples include the Audi R8, BMW M5, Ford Mustang GT, Lexus LC 500h and Porsche 911. A new high-grip silica compound is aimed at flexibility and road adhesion.

A dynamic taper design and revised rib design are meant to spread contact pressure more evenly, and the asymmetric tread allows cross-rotation to reduce irregular wear. Widths of 285 and above get an extra center rib. Treadwear warranty: 25,000 miles (rear tires on staggered fitments are covered for 50% of that).

Specifications for this tire: size 275/40ZR18 99Y; fits 18-inch wheels; section width 275 mm; aspect ratio 40; load index 99; speed rating Y; overall diameter about 26.7 in (677 mm). Part number toy133180.

IMPORTANT: Summer tire. Toyo rates its winter handling at zero, so plan on a separate winter set. Warranty terms are set by Toyo; see Toyo's limited warranty for details.
