The Discoverer ST Maxx is Cooper's toughest new
off-road commercial grade traction tire that is also designed to provide exceptional on-road handling and enhanced
ride comfort. Developed for drivers of trucks, large vans and SUV's, the ST Maxx uses a 3-ply Armor Tek-3
construction for added strength and durability.
A tough new silica and natural rubber cut and chip
resistant tread compound combined with the Armor Tek-3 construction creates a tire that better withstands the
punishing impact of rocks and other materials against the sidewall and tread area. Cooper has added an angled ply
construction to disperse the forces of impact that can severely damage any tire. The result is a tire that can take
a beating and just keep on going.
The hybrid 4-5 rib tread design and other tread
features give the ST Maxx more than capable on-road performance as well. The tread block pattern creates increased
water evacuation from under the tread and better wet surface driving. This is an area that most every review
mentions as being a real plus on this tire compared to the competition in this class.
Another area that we need to mention is how much
more quiet this tire is compared to other similar tires. It will surprise when you first drive it at highway speeds
and wonder why you aren't hearing a lot of excess noise.
Cooper has also included the little extras that you
would expect on an AT tire, like stone ejector ribs around the tread. Built into the lateral grooves, these ejector
ribs quickly rid the tire of mud buildup, rocks and stones, and other debris. The ST Maxx carries an E load rating
for those who use their trucks for heavy-duty load carrying. Cooper has built this model with studdable lugs for
those who live in an area where increased snow performance is a must.
Exceptional off road performance on a variety of
Excellent street manners
Wet handling is outstanding
Very low road noise
Long lasting treadlife
Limited size range
Cooper has come up with a pretty good combination
between an off-road tire that aggressively goes through all types of terrain, while also having the street manners
to be driven on a regular basis. You would think the tread design and style of this tire would make it unacceptable
for street or highway driving, but that's not the case. This model is also surprisingly quiet for a tire in this
class. Whether around town or on the highway, there is no excessive tire noise.
Treadlife is exceptional, and the Armor-Tek3
provides excellent rock puncture resistance when the tires are aired down. Our only wish is that Cooper would add
more sizes to the lineup. Overall, if you are wanting a tire for off-road use, yet also need it to be driven on the
street, the Discoverer ST Maxx is one of the best.
