Product Details

Built to conquer the toughest worksites, the Discoverer S/T MAXX tire delivers rugged durability and reliable performance on challenging terrain. With its aggressive tread and reinforced construction, it makes tough terrain an easy task, offering the strength and traction needed for demanding jobs.

Snow Peak Rated

The 3 Peak Mountain Snowflake symbol indicates the tire is rated for Severe Snow Service. This is the acceptable standard for winter driving in Canada and provides improved safety on snow and ice.

Mud And Snow Rated

The M+S symbol differentiates an All-Season tire from a Summer only tire. While rated for light snow, they will not match a winter tire for traction or stopping distance on snow and ice.

Accepts Studs

This tire can have studs installed to provide additional mechanical traction on icy surfaces. Studded tires are prohibited by law in many provinces. Ask at your local Canadian Tire store.

  • Features Cooper’s proven and reliable 3-ply “Armor-Tek3®” carcass construction combined with a new, proprietary cut and chip resistant tread compound

  • With that combination along with its modern hybrid 4-5 rib tread design and unique tread features, the S/TMAXX is destined to be a commercial grade traction tire that will perform in the toughest terrains while retaining remarkable on-road traction, stability and low noise characteristics

  • Cooper's proven, class-leading 3-ply Armor-Tek3 construction contributes to the durability of the S/TMAXX by adding strength to the sidewall and tread area

  • A unique angled ply construction absorbs and helps dissipate tire impact forces that can damage a tire in harsh off-road conditions

  • The tread compound is formulated with a unique blend of natural rubber and silica that provides exceptional wet traction and confident handling on the highway, while also delivering excellent cut and chip resistance on unpaved, rocky and gravel terrain

  • Strategically placed ribs within the lateral grooves of the tread design help to discharge stones and resist stone drilling

  • The optimized design of the buttress area provides additional off-road traction, abrasion and puncture resistance

  • Rugged design minimizes the potential for damage due to scrapes and abrasion when used in difficult terrain

  • Wheels sold separately

Great every where but Mud and FWY

3 years ago
Ive had these for well over a year. Drove them to Utah, Arizona, Nevada, up the 395 in California, a Few trails in Big Bear and all the popular trails in SoCal. Ive used them with confidence in Snow, dirt and rocks. They are a let down in Mud ... They tend to pack mud to the point you wont get traction and its like skating on ice. The other down side is ... alot of people say they pull to the right. But they seem to wonder for me on the freeway. To the point that it becomes a chore driving long distance. Play with tire pressures from 33 to 40psi. They still wonder from 60 to 70mph. But once you get close to 80mph or pass 75mph. The wondering slows down. The wear is good. But like I said Im tired of the wondering on the freeway and constantly watching out for it... Will try to move on from these as soon as I decide which ones I want to go with.

No, I do not recommend this product.

Q: quel est l'indice de bruit en DB de cet article?

6 years ago
Translate with Google
1 Answer
  • A: Nous mesurons le bruit en tant que mesure métrique de bruit de passage et cette ligne varie de 72 à 77 en fonction de la taille du pneu recherché. Mais ce n’est pas nécessairement la valeur en cabine car cela peut varier considérablement selon le véhicule et les méthodes NVS employées pour maintenir une cabine silencieuse.
