The Michelin Latitude Sport is a summer performance tire for SUVs, using the same track-inspired tread pattern and rubber compounds as the Pilot Sport 2. It is not just a larger version of that tire, but one engineered for a heavier vehicle.
It aims for strong dry grip, and FAZ Technology places reinforcing filaments under the tread for a stable feel and crisp handling at speed.
The 255/55R18 size is rated 109Y for load and speed with extra load (XL) construction. It offers 10/32-inch tread depth, a 50 psi maximum inflation pressure, a UTQG rating of 220AAA and an overall diameter of about 29 inches. This size carries a 20,000-mile treadwear warranty.
