## Description

The Cooper Discoverer Rugged Trek All-Season LT285/70R17 121Q 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.

## Features

- Off-road strong & on-road smooth
- Dual-sidewall design so you can pick your favorite to show off on your drive
- Treadwear Warranty: 55,000 miles
- Up to 30% Deeper Tread than our traditional All-Terrain Tires

- Standard Limited Warranty

## 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.

*by P***4 on November 23, 2024*

My previous tires were the Nitto Grappler which were extremely dangerous and super slippery when driving in the rain but wow I was blown away at the huge difference with these new Coopers, truck drives like a luxury sedan, I’m not scare to drive in the rain anymore, they are excellent in wet and dry conditions, they look very rugged yet they are super quiet, they are really smooth and they improved the ride quality big time, best value for the money out there. Highly recommend!
