I've had these tires for about 50,000 miles and now it's finally time to replace them. Probably rotated them three times.

Can't say enough good things about these tires. Had the last set on my FJ Cruiser for a bit over 80,000 miles and only ever had three flats (2 from bad valve stems). If you can except the fact that these are harder, noisier tires, they will not disappoint you.

These are the best tires I've had on my 17 Ram 2500 45,000 miles out of them. I like them so much I'm on my second set. I've tried some other tires and they did not last. SoðŸ' To these tires.

Excellent tire so far. I have had them on a '96 landcruiser for the past year and a half. Tires have spent most of the time in the southern california heat and sun with no visible weathering or cracking. I've put nearly 60k miles on these, and I'd say I have another 30-40k left before I'd consider replacing them. Am simply amazed at how well these are holding up. They do great in dry and wet weather. Have had good success in snow, although on straight ice they can get a bit squirrely, as there isnt a whole lot of siping. On sand they arent great at higher pressure (few are) but once you drop the pressure down, and I mean way down (sidewalls are stiff) they perform great. Magic psi is around 13 for sand. I routinely run them at 40psi on the street. Leads to a slightly stiffer ride, but the longevity you get from the tire due to the added pressure is far and above worth it. I WILL be buying a set of these again!

This is my second set of st maxx's that I've had on my Tacoma and I don't think I could ever run anything else. I had a 33 before with 40k miles on them and only changed because I wanted 35s. The fact that it's an "all terrain" so it keeps the sipes for wet traction and doesn't eject the snow for snow on snow traction in the winter makes this one of the best tires in my opinion. Durable as hell I take these on tough tracks from blacks at rausch creek offroad park and harsh class 4s in VT that would slice through any other tire, the Kevlar reinforcement is tough! That being said they are a heavy tire, the 33 was a load range e but the 35s are d so it hasn't really changed drastically going up in size for me. Road noise doesn't start bad but you'll really start it to hear it once they break in, nothing awful but having a conversation on the highway with the radio down and you'll know it's there. Expect amazing traction on and offroad in all conditions from rock crawling, snow, rain, just maybe not mud. For that you'll want the lockers on and to floor it. Just expect that mpg to tank as a sacrifice for the traction.

Get technical:

An all season tire that's designed for use on commercial light trucks and high powered torque vehicles, the Discoverer S/T Maxx offers drivers on road stability and performance along with off road capabilities.



Features & Benefits

  • All-season tread
  • Outlined White Letter or Black sidewall depending on the tire's size
  • Features a cut and chip resistant tread compound for added off-road durability
  • Can be pinned with studs to enhance traction in severe winter weather conditions

In most cases, commercial drivers need a tire that can perform off road as they navigate to the highway. Fortunately, Coopers Tires designed the Discoverer S/T Maxx with these drivers in mind, as its cut and chip resistant tread compound provides drivers with added defense for off road applications. Stone ejector ribs force stones and other debris out of the tread for consistent traction, and the Discoverer S/T Maxx also features groove walls for added stone ejection. Built with an Armor Tek3 construction to improve durability, the Discoverer S/T Maxx also offers drivers a quiet ride and longer tread life thanks to its hybrid 4-5 rib design.
