SunF 21x7-10 Front & 22x11-9 Rear ATV UTV Knobby Sport Tires

In this review of the SunF A027 set, the bottom line is clear: these tires are built for riders who want aggressive, race-oriented traction without the price of premium labels. Designed as a matched set of two 21x7-10 front and two 22x11-9 rear knobby tires, the A027 delivers dependable grip across mud, sand, and loose gravel thanks to its angled tread and shoulder traction technology. For racers and weekend trail riders after predictable handling and strong wear resistance, this set offers the best balance of value and off-road performance in its class.

Key Features

• Matched front and rear sizes: Includes two 21x7-10 fronts and two 22x11-9 rears for a true race-ready setup on appropriate rims.
• All-terrain racing capability: The aggressive footprint and angled tread pattern provide consistent traction across mud, sand, and rough tracks for confident acceleration and braking.
• 6-ply construction: A durable 6 PR build resists punctures, cuts, and impacts to handle the demands of racing and rough trail use.
• Shoulder traction technology: Reinforced shoulders improve grip during high-speed turns and technical maneuvers to enhance rider control.
• Tread depth and load capacity: Deep tread (14 to 14.5 mm) and stated load ratings make these tires suitable for spirited riding and heavier loads on common ATV/UTV setups.

Who It's For

These tires are aimed at off-road racers and aggressive trail riders who need a knobby, performance-oriented tire that works well in a variety of loose and uneven surfaces. Owners of ATVs and UTVs that accept 21x7-10 front and 22x11-9 rear sizes will find the A027 set an economical way to boost traction and cornering confidence.

Riders who primarily use pavement, seek ultra-quiet touring tires, or require specialized mud or rock-specific compounds should look elsewhere, since the A027 is optimized for XC, desert, and mixed off-road conditions rather than highway use or extreme rock-crawling.

Pros & Cons

Pros
