Cooper Discoverer STT PRO Above the Treeline

We put Cooper's new Discoverer STT PRO through the paces this past week on the scenic trails of Ouray, CO at the 9th Annual FJ Summit sponsored by Discount Tire. Those of you that have been to Ouray know that the terrain can change from one corner to the next and high altitude passes demand tires that don't slip. To us, it's a great location to put some new rubber to the test. As an added challenge, it rained nearly every day at the event so our Discoverer STT PRO equipped 2WD Tacoma had it's work cut out, or so we thought anyway.



The silica infused rubber compound provided the necessary grip on wet rocks and the asymmetrical scallops on alternating lugs, combined with the optimized 3-2 tread pattern, delivered solid traction and clean out in the slop. That said, we did find one spot on Imogene Pass that required us to get a little tug (the S-turn towards the top of the trail). The combination of slippery mud, tight turns, 2WD, and an incline was just enough to hold us up. If we would have had 4WD we would have pulled right through it.



In addition, we put approximately 1,000 highway miles on this tire making our way to and from Ouray. The tires tracked well down the road and were responsive to our steering input. There was some road noise present, but this is to be expected from an aggressive tire like this; with the windows up and the radio on, we quickly forgot about any tire noise.

We think Cooper hit the nail on the head with the STT PRO and it is an excellent option to consider for the enthusiast who spends a decent amount of time off-road but still needs on-road reliability and handling. If you're running a set of Discoverer STT PRO tires let us know what you think here; we, as well as Cooper, would love to hear from you.

Nice post thanks I saw a set on a truck the other day looked good in person...

 

Thanks, lyodbraun. We are very pleased with the new STT PRO.

 

Looks like the making of a great tire. I wished they made them in LT255/85/R16.

 

We've had a few people request that size so far; tall and narrower is quickly gaining popularity. I checked with Cooper and 255/85R-16 is not being considered at this time. I'll pass your comment along.

 

So that 2WD truck made it through all that mud. Wow.

That's some nice rubber.

 

No. 2WD got stuck, needed a tug to get out.

 

Any idea if there will be a plan in the future for a 285/75/16?

 

We weren't stuck per se, just needed a little assistance up the aggressive incline; we would have needed the tug regardless of tire

Yes, the STT PRO will be produced in the LT285/75R-16 size but as of right now there is no firm ETA. The Cooper representative I spoke with on the phone said possibly within the next couple of months.

 

Any idea when the 315/75/16 will be released?

 

I checked with Cooper and they have stock available now which means we can order a set for you. Our current mail order price is $302.00 each with FREE delivery. Give us a call at 1.888.459.4080 when you're ready to pull the trigger an anyone of our sales agents will take care of you

 

What size is on the tacoma in the picture above?

 

We need an STT Pro in 255/85r16... does anyone know if there is a plan for them to come out with one?

 

The answer is in the posts before you

 

Indeed it is...so sad. I stick with the 235s or switch to the MAxx..life is hard
