Sumaxx All-Terrain A/T tire

Summary

All-Terrain A/T is an all-terrain tire from SUMAXX, the tire brand of Qingdao Sunforce Tyre in Qingdao, China. It is designed for pickups and SUVs used both on the road and off road, with small grooves that eject mud from the tread, a special compound that resists wear on gravel and rocky roads, and an extra-strong sidewall. Subphaisal lists it under the shop product name "A/T White Letter", in 16–20 inch sizes.

Key technology

Mud-ejecting groovesSmall grooves between the tread blocks push mud out, so the tire keeps good grip on muddy tracks.
Special compoundThe maker adjusted the materials so the tread resists wear better on gravel and rocky roads.
Tread for on-road and off-road useThe tread pattern spreads pressure evenly across the tread for even wear.
Reinforced sidewallHelps protect the sidewall from side impacts when driving off road.
3D sipesThe maker says they help grip on snow. (This is not a snow tire, though: it does not carry the 3PMSF symbol, per the EU tire label database.)

FAQ

Is the SUMAXX All-Terrain A/T good?

Yes, for pickups and SUVs driven both on the road and off road. The maker designed the tread to eject mud, resist wear on gravel and rocky roads and wear evenly, with an extra-strong sidewall to protect against side impacts.

Is the SUMAXX A/T quiet?

Quietness is not a strength the maker promotes. The maker's website does not mention noise, and the EU tire label for 265/70R16 112T lists external noise at 72 dB (class C). Actual quietness depends on the car, speed and road surface.

Can the SUMAXX A/T handle mud?

Yes. The maker says small grooves push mud out of the tread so the tire keeps good grip. But this is an A/T tire designed for both on-road and off-road use. If you mainly drive in heavy mud, SUMAXX has a separate M/T line.

Where are SUMAXX tires made?

SUMAXX is a brand of Qingdao Sunforce Tyre Co., Ltd., based in Qingdao, China. The brand started in 2012, and the maker says it has customers in more than 80 countries and regions. The maker's website does not name the plant. You can see the country of manufacture printed on the sidewall.

What cars is the SUMAXX A/T for?

Pickups and SUVs that use 265/70R16, 265/75R16, 265/60R18, 265/50R20 or 275/55R20, the sizes Subphaisal carries. Check the size on your current sidewall before ordering.

What warranty does the All-Terrain A/T have?

Every tire bought from Subphaisal is covered by the manufacturer against manufacturing defects for 2 years or 50,000 km, for both store pickup and delivery. See the warranty page for details.
