Set of 4 SunF 145/70-6 Quad ATV UTV Tires - Quiet Street Grip

In this review of the Set of 4 SunF 145/70-6 Quad ATV UTV Tires the bottom line is simple: these are a practical, value-focused tire set for riders who need reliable street performance and occasional off-road use. The SunF A021 is a street-type, non-knobby tire offered in a medium compound that delivers surprisingly good grip and low noise on pavement, making it a smart pick for compact ATVs, quads, or UTVs with 6 in rims where race-style offroad treads are not allowed.

Key Features

• Size: The 145/70-6 dimension is tailored to small quads and utility vehicles, providing a predictable contact patch for street and light off-road riding.
• Quad Set: Sold as a total of four tires, the set ensures matched tread and handling characteristics across all wheels for balanced performance.
• 6 in Rim Compatibility: Designed for 6 in wheel diameter, these tires install cleanly on standard small ATV rims without unusual adaptations.
• Medium Compound: The premium rubber medium compound offers increased traction on pavement while remaining durable enough for mixed-use conditions.
• Street-Style Tread: The non-knobby profile reduces road noise and improves ride quality on paved surfaces compared with aggressive off-road treads.
• 6 Ply Construction: Built with a 6 ply rating for durable resistance to punctures and impacts typical of utility and recreational riding.

Who It's For

These tires suit riders who primarily use small ATVs or quads on paved roads, tracks where street-type tires are required, or for light-duty trail work where a quieter, smoother ride matters. The set of four is convenient for owners who want consistent handling and matched wear across their machine.

Riders who need extreme mud, deep sand, or heavy rock crawling performance should consider more aggressive, knobby tires or higher ply-rated off-road models. Also, those with larger UTVs that require 14 in or larger rims will need a different size option.

Pros & Cons

Pros

• Quiet on pavement and praised for ride quality during street use.
• Tires quality and grip are often noted as better than expected for the price.
• Set of four provides consistent handling and value for money for small quads.
• Medium compound balances traction and wear for mixed street/light off-road use.

Cons
