## Description

The Cooper Discoverer Rugged Trek All-Season 275/60R20 115T Tire is an all-season pickup truck and SUV tire that looks tough because it is tough. It looks aggressive but it also has nice manners. The Rugged Trek has a unique Rough Terrain pattern, which is trail capable and provides extra grip and confidence when you venture off the highway. It also features Stone Blockades, which are ridges in the tire pattern to help keep pesky stones and rocks out of the tire and on the ground where they belong, helping protect the tire from damage when you’re off the beaten path. Rugged Trek is built to provide enhanced grip on wet roads and features Whisper Grooves Technology that blocks the rush of air through the tire, helping to eliminate noise when on the highway. There are dual sidewall designs so you can pick between the Mountain Pass pattern or Knife-Edge pattern, which gives you double the options for your look. Our aggressive tread blocks are designed for quiet on-road performance and deep treads help grip in sticky mud and sand. While this is a tough-looking tire, it is also engineered for a quiet and comfortable drive.

## Questions & Answers

**Q: Do these comes with white letters**
A: This is an all black letter tire. Thanks.

**Q: Hello. How can I choose one of the two different designs of the side part of the rim? Thanks.**
A: Hello, thank you for reaching out. We don't sell rims through our Amazon store sadly.

**Q: Will this for 2018 Toyota Tundra with stock wheels and stock setup?**
A: No. You will need a leveling kit at an absolute minimum as well as offset wheels or 1.25” wheel spacers. If you do wheel spacers make absolute sure that they are hub centric not stud centric. 
I have a 19 tundra running 35’s on stock limited wheels with spidertrax spacers and a 3” lift from Toytec.

**Q: Will I need a lift kit for my 2015 gmc sierra?**
A: I would call GMC and Cooper Tires.

Will update performance at a later date but maaaaan do these look tough 💪Ok, I'm back. Balanced well. Roll smooth. Surprisingly quiet. Hold the road. Look badass. Amazing tires and they're F rated. Did i mention they look badass? If you're shopping for tires, look no further fellas. You won't be sorry

### ⭐⭐⭐⭐⭐ Best tires yet!
*by  on Reviewed in the United States June 23, 2026*

Great tires for great price deal. Smooth ride. I was skeptical if would be loud and hard too balance like others was saying but i was wrong. And the looks of it on my suv looks badass. 🤙🏼

### ⭐⭐⭐⭐⭐ Impressive to say the least
*by  on Reviewed in the United States April 2, 2024*

***UPDATED***Mother Nature finally allowed me to get a better idea about these tires. I have so far run them through deep mud, heavy rain (1” an hour or heavier), dry roads and on mild rocks. No sand or snow here in Central Arkansas this time of year. So I haven’t aired these down at all, been 36 psi. In the wet these are great. Plenty of contact in heavy rain to provide a feeling of confidence at hwy speed. In the dry these are VERY quiet for such an aggressive tread. I have honestly had more tire noise from some AT tires. In the dirt and rocks these take everything I throw at them and want more. I easily scrambled over everything I encountered on the trails. In the mud these tires clean themselves out nicely. I had no caking as I rolled through mud about 1-2” deep. I am very pleased with these tires. Worth every penny I spent and will gladly buy again. Hope this helps y’all a little. I will update snow when winter comes around again. For now, kudos to cooper for a great set of tires
