Gripmax SureGrip Pro Sport summer tire

The Gripmax SureGrip Pro Sport is a high-performance summer tire built for passenger vehicles. It carries a 275/30R21 size with a 98 load index and Y speed rating for sustained speeds up to 186 mph. The XL designation marks extra load capacity for heavier sedans, SUVs or CUVs.

Fitment checks before ordering

Verify that your wheels are 21 inches in diameter and accept a 275 mm section width. Confirm the vehicle manufacturer approves a 30-series aspect ratio and a load index of at least 98. Ensure summer compound tires match your climate, as they lose grip in cold or snowy conditions.

Sustained driving behaviour

A UTQG treadwear rating of 280 and a 10/32 inch tread depth support a projected 50,000 mile treadlife under normal use. The AA traction grade indicates strong wet braking on hot pavement. The 4-ply XL construction resists heat buildup during extended high-speed runs.
