SUPER73 GRZLY 20″ x 4.5″ Override Tire – Aggressive Off-Road Knobby Tread

Break away from the pavement and conquer rugged fire roads with the genuine OEM SUPER73 GRZLY 20″ x 4.5″ Tire with Override Technology. Engineered for riders who demand aggressive dual-sport performance, the GRZLY blends a moto-style aesthetic with maximum utility. It delivers relentless traction across shifting sand, mud, and loose loose dirt while maintaining stable, predictable tracking on hardpack gravel and city streets.

Aggressive Knobby Profile with Signature Styling

The GRZLY casing is meticulously sculpted to handle high-torque electric powertrains across unpredictable backcountry tracks:

• Deep Block Tread Layout: Features pronounced outer lugs that dig into loose earth, ensuring consistent traction and confidence when leaning hard into dirt corners.

• Signature Branding: Meticulously incorporates integrated SUPER73 “Lightning Bolt” styling cues directly into the tread patterns, blending functional water-clearing channels with classic factory aesthetics.

• All-Weather Performance: Proven across everything from desert singletrack to light winter snow slop, acting as a true year-round workhorse tire.

Heavy-Duty Override Puncture Protection

Worrying about sharp debris cutting your trail rides short is a thing of the past. Upgraded with SUPER73 Override technology, this tire features a reinforced internal protective belt built right into the casing framework. This structural defense barrier reduces flats up to three times compared to lightweight, entry-level standard fat bike tires, shrugging off stray wire, sharp gravel chunks, and glass shards.

Staggered Setup & Front Clearance Placement

• The Go-To Front Steering Standard: On high-end platforms (like the R-Series, S2, and Adventure Series fleets), this 4.5-inch wide profile typically serves as the front steering tire, paired with a wider 5.0-inch GRZLY layout on the rear rim to optimize weight distribution.

• All-Around Uniform Configuration: Functions flawlessly as both a front and rear tire on Z-Series frames (such as the ZX or Z Adventure), providing a balanced, quick-steering profile without causing chain alignment or frame clearance friction.
