Gripmax SureGrip Pro Sport 325/30R21

The Gripmax SureGrip Pro Sport is a high-performance summer tire sized 325/30R21 for light trucks and SUVs. It carries a 108 load index and a Y speed rating allowing up to 186 mph. The XL load range supports heavier vehicle weights. A 280 UTQG treadwear rating and 28.7 inch overall diameter complete the specification.

Drivers wanting dry and wet summer grip

This tire suits drivers who need strong summer traction and high-speed stability on trucks or SUVs. It is not for buyers who require winter or all-season traction. It is not for vehicles that need a different rim diameter or section width. It is not for applications requiring run-flat capability.

Sustained high-speed summer driving

Under sustained load the tire maintains its Y-rated speed capability and XL load capacity. The 280 treadwear compound resists wear over long distances, with a rated treadlife of 50000 miles. The 10/32 inch tread depth provides consistent contact patch stability during extended high-speed runs. Heat buildup is managed by the summer compound formulation.

Questions about this item

Does the 21-inch rim diameter match my vehicle's wheels?

The tire is built for a 21-inch rim, so it will fit any wheel with that exact diameter and the correct load rating for your SUV or truck.

Will the 325-millimetre section width clear my existing suspension and fenders?

At 325 mm wide with an overall diameter of 28.7 inches, the tire needs adequate clearance; verify your vehicle's specified width and offset before mounting.

How can I confirm the tire is performing correctly after installation?

Check that the sidewall shows the 108Y XL markings, measure tread depth at 10/32 inch, and monitor even wear over the first few thousand miles.
