Patented Armor Tek3 tire technology adds strength to the tire sidewall, providing increased resistance to damage while driving over boulders and uneven, tough terrain. The Discoverer STT Pro comes with rubber formulated to combat shredding and damage from stones and off-road obstacles. The ROCK CLIMBER SIDEWALL gets max traction to help conquer even the toughest obstacles with deep ‘Climber Cleats’ and Flex Grooves built into the side of the tire that grip jagged rocks and power through thick mud. The MUD SLINGERS 2.0 are deep, wide trenches with additional notches throughout the tread combine to give you more grip to power through and help continuously clear thick mud from the tire. The EARTH DIGGERS can tackle tricky terrain with large blocks with alternating mud scoops that forcefully dig into loose dirt, sand or sticky mud. The STONE ARMOR TECHNOLOGY provides the ultimate durability with channels, ridges, and edges designed to help defend against sharp rocks and debris while expelling lodged stones. ## Features - All-Season Off-Road Traction Tire - The most extreme all-season, off-road tire Cooper offers to date - Provides remarkable off-road performance without sacrificing on-road traction - Tread design helps to prevent stone retention - Armor Tek3 construction for added tire durability ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BBWD4DG7 | | Automotive Fit Type | Universal Fit | | Best Sellers Rank | #145,108 in Automotive ( See Top 100 in Automotive ) #160 in Light Truck & SUV All-Terrain & Mud-Terrain Tires | | Brand | Cooper | | Brand Name | Cooper | | Construction Type | Radial | | Customer Reviews | 4.7 out of 5 stars 400 Reviews | | Global Trade Identification Number | 00029142969860 | | Included Components | Tire Only | | Item Diameter | 34.57 Inches | | Item Dimensions | 34.8 x 34.8 x 12.6 inches | | Item Type Name | Tire | | Item Weight | 69.5 Pounds | | Load Capacity | 3195 Pounds | | Load Index | 121 | | Load Range | E | | Manufacturer | Cooper | | Manufacturer Part Number | 170255034 | | Manufacturer Warranty Description | Standard Limited Warranty | | Maximum Pressure | 65 Pound per Square Inch | | Model Number | 170255034 | | OEM Equivalent Part Number | 170228011 | | Ply | 10-Ply | | Rim Size | 17 Inches | | Rim Width | 10 Inches | | Seasons | Year Round | | Section Width | 12.5 Millimeters | | Size | 35X12.50R17LT 121Q | | Spare Tire Mounting Location | Front or Rear | | Speed Rating | Q | | Tire Aspect Ratio | 72 | | Tire Diameter | 34.57 | | Tread Depth | 21 32nds | | Tread Type | Non-Directional | | UPC | 029142969860 | | Unit Count | 1.0 Count | | Vehicle Tire ISO Metric Size Description | 317.5/35R17 | ## Product Details - **Brand:** Cooper - **Load Capacity:** 3195 Pounds - **Load Index:** 121 - **Rim Size:** 17 Inches - **Section Width:** 12.5 Millimeters - **Size:** 35X12.50R17LT 121Q - **Speed Rating:** Q - **Tire Aspect Ratio:** 72 - **Tread Depth:** 21 32nds - **Tread Type:** Non-Directional ## Images ![Cooper Discoverer STT Pro All-Season 35X12.50R17LT 121Q Tire - Image 1](https://m.media-amazon.com/images/I/81yAZbtaAIL.jpg) ![Cooper Discoverer STT Pro All-Season 35X12.50R17LT 121Q Tire - Image 2](https://m.media-amazon.com/images/I/81I28TchhBL.jpg) ![Cooper Discoverer STT Pro All-Season 35X12.50R17LT 121Q Tire - Image 3](https://m.media-amazon.com/images/I/81xvHD9ODOL.jpg) ![Cooper Discoverer STT Pro All-Season 35X12.50R17LT 121Q Tire - Image 4](https://m.media-amazon.com/images/I/91YhnE1-VBL.jpg) ![Cooper Discoverer STT Pro All-Season 35X12.50R17LT 121Q Tire - Image 5](https://m.media-amazon.com/images/I/51giAMFQoeL.jpg) ## Available Options This product comes in different **Size** options. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/478576897-cooper-discoverer-stt-pro-all-season-35x12-50r17lt-121q-tire](https://www.desertcart.us/products/478576897-cooper-discoverer-stt-pro-all-season-35x12-50r17lt-121q-tire) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-15*
