Dunlop Grandtrek ST20 All-Season Light Truck & SUV Tire

The Dunlop Grandtrek ST20 is an all-season highway tire engineered specifically for light trucks, crossovers, and SUVs. Carrying the M+S (Mud and Snow) rating, it is a proven original equipment (OE) and OE-replacement tire that delivers confident, comfortable, and capable year-round performance across a wide range of driving conditions. Backed by Dunlop's century-plus legacy of tire engineering — a heritage tracing back to the invention of the pneumatic tire itself — the Grandtrek ST20 balances everyday traction, low road noise, and long-wearing durability in a single capable package.

All-Season Traction and Wet-Weather Performance

• M+S-rated all-season tread compound maintains rubber flexibility across a broad temperature range, providing consistent grip in dry, wet, and light snow conditions
• Symmetric tread design works in concert with the all-season compound to enhance road-gripping ability throughout all four seasons
• Circumferential grooves channel water and slush away from the contact patch, resisting hydroplaning and improving wet-weather safety
• Advanced tread compounding delivers enhanced wet-weather capability alongside even, long-lasting tread wear

Handling, Stability, and Steering Response

• Center rib tread pattern maintains consistent road contact for improved steering responsiveness and driving stability at highway speeds
• Rounded shoulder blocks increase biting edges during cornering and maneuvering for greater confidence and control
• Construction tuned to resist deformation under driving forces, contributing to precise, responsive handling

Quiet, Comfortable Ride

• 5-Pitch Tread Design Technology sequences tread blocks to break up and cancel sound waves before they reach the cabin, significantly reducing road noise
• Variable pitch sequencing minimizes tread pattern resonance for a refined, comfortable experience during both daily commuting and long-distance travel

Appearance and Warranty

• Black serrated sidewall with raised black letter branding delivers a bold, truck-appropriate appearance
• Covered by Dunlop's Highway Auto and Light Truck Tire Replacement Limited Warranty for added peace of mind

Whether used as a direct OE replacement or as a value-oriented all-season upgrade, the Grandtrek ST20 is an ideal choice for SUV and light truck drivers who demand reliable year-round capability without sacrificing ride comfort or tread longevity.
