This listing is for new Cooper Discoverer S/T Maxx 35X12.50R15 C/6PLY BSW Tires. Manufacturer part number: 170166004.

The Cooper Discoverer S T Maxx is a heavy duty all terrain tire built for drivers who need exceptional durability, strong off road traction, and stable performance on demanding terrain. It uses Cooper’s Cut and Chip resistant rubber compound that helps the tire withstand rough surfaces, sharp rocks, and abrasive trails. This makes the S T Maxx a dependable option for work trucks, overlanding setups, and drivers who spend serious time off the pavement.

The tread design blends elements of a mud terrain tire with the stability of an all terrain pattern. Large, deep tread blocks provide confident grip in dirt, gravel, and mud, while the built in stone ejectors help keep the tread clear by pushing out trapped debris. Cooper’s Armor Tek3 construction reinforces the sidewalls with an extra layer of protection, improving impact resistance and helping guard against punctures. The alternating shoulder lugs increase side bite and offer added traction when navigating ruts or uneven ground.

Best Suited For

The Cooper Discoverer S T Maxx is ideal for light trucks, full size SUVs, off road rigs, work trucks, overland vehicles, and drivers who regularly tackle rocky terrain, deep dirt, gravel, and rugged backcountry roads. It is a great fit for drivers who need extreme durability paired with dependable on road stability.

Description

Sidewall

BSW

Describes the sidewall appearance. Examples: BSW= Black Side Wall, WSW = White Side Wall, OWL = Outlined White Letters.

Load Index

113

The load index (LI) is a 2- or 3-digit number that correlates to the maximum amount of weight the tire can carry. For example, a tire with a load index of 87 indicates that the tire can carry a maximum load of 1,201 lbs. In this particularly example, 4 tires (each with a load index of 87) can carry a maximum of 4,804 lbs. Refer to your vehicle owner's manual for the recommended minimum load index.

Speed Rating
Tires speed rating

Speed rating (SR) indicates the maximum speed the tire can achieve. Higher speed ratings are typically associated with better handling capabilities. Refer to your vehicle owner's manual for the recommended minimum speed rating.

Load Range/Ply Rating

C/6PLY

Ply rating, more commonly referred to as load range, represents the strength and durability of the tire. Higher ratings may indicate your tires can handle heavier loads.

UTQG

Not Available

To help consumers evaluate their tires, the U.S. National Highway Traffic Safety Administration (NHTSA) created the Uniform Tire Quality Grading System (UTQG). The UTQG rates tires are rated on their tread-wear, traction performance, and temperature resistance. The grade for each of these can be found on the sidewall of your tire (except for winter tires and certain light truck tires).

Max Single Load(lbs)

2535

The maximum load this tire will support. Remember to multiply this number by the number of tires installed on your vehicle to get the maximum carrying capacity. This number is directly related to the Load Index.

Max Single Air Pressure(PSI)

The maximum air pressure this tire will support. This does not represent the amount of air pressure your tires should have at all times. Consult with your owner's manual to determine the best air pressure you should use for your vehicle.

Tread Depth

18.0

The amount of tread on the tire. Once the tire is worn to 2/32nds, it is considered fully used and should be replaced at that time. Most tires will have tire indicators in the grooves of the tire to help you determine when the tires are worn down to 2/32nds.

Tread Design

Nondirectional

The pattern of the grooves, lugs, voids, and sipes on a tire's surface. This design affects the tire's traction, handling, and noise characteristics. Common types include symmetrical (uniform pattern across the tire), asymmetrical (different patterns on the inside and outside for varied road conditions), and directional (designed to rotate in one direction for improved wet traction and hydroplaning resistance).

Rim Width Range

8.5-11.0

The approved wheel rim width range this tire will support.

Measured Rim Width

10.0

The recommended wheel width as recommended by the tire manufacturer to get the best wear us performance for this tire.

Section Width

12.2

The measurement from sidewall to sidewall.

Tread Width

10.31

The measurement from one side of the tread to the other side of the tread.

Overall Diameter

34.45

The height of the tire when fully inflated.
