Set of 4 SunF A021 TT Sport ATV UTV Flat Track Tires - Street Ready

In this review of the SunF A021 set of 4 TT sport ATV tires, the bottom line is simple: this kit is aimed at riders who want a street-oriented, hard-pack capable tire that delivers consistent grip and quiet pavement manners. The A021 is a non-knobby, medium-compound tire built for paved trail roads and compacted trails, and the reviewer found it best for ATV and UTV owners who prioritize traction on tarmac-like surfaces and predictable cornering. It is not a mud or deep off-road tire, but where allowed on racing circuits or street riding, it shines.

Key Features

• Front and Rear Fitment: Includes two 23x7-10 front and two 20x10-9 rear tires to match common ATV and small UTV wheel setups for balanced handling.
• 6 Ply Construction: The durable 6 PR build provides toughness and resistance to road hazards on paved and hard-pack surfaces for regular trail use.
• Street-Oriented Tread: The non-knobby flat track design improves stability and cornering on pavement while reducing road noise compared with aggressive off-road tires.
• Medium Rubber Compound: The medium compound enhances grip on hard surfaces and gives predictable traction for both casual riders and racers in non-offroad classes.
• Tubeless Design: Tubeless configuration simplifies mounting and allows lower risk of pinch flats when properly installed on compatible rims.
• Wide Size Availability: The A021 family spans from about 13 to 26 in sizes, offering options for a variety of ATV and UTV models beyond this specific set.

Who It's For

The SunF A021 set is best for ATV riders who spend most of their time on paved trail roads, park roads, or compacted hard-pack trails and who want a quiet, grippy tire for street-like conditions. racers in classes that disallow knobby tires will also find the non-knobby profile appropriate for competition use where permitted.

Riders who frequently tackle deep mud, loose sand, or heavily rutted off-road trails should look elsewhere for more aggressive, knobby tread patterns designed specifically for soft-surface traction. Also note that rims are not included, so buyers must have compatible 10 in front and 9 in rear wheels available.
