Have around 55,000 miles (mostly towing a 40' flatbed gooseneck) on them now and they are about 30% tread.

Good ride for a load range E rugged terrain tire. Was impressed with snow traction. I did not even have to engage 4WD on a snow covered steep hill in a relatively light weight Gladiator Pickup. Ice is less good, but to be expected. Fuel economy dropped, but I increased diameter over 2 inches and moved from a highway tire so to be expected. ## Frequently Bought Together - Cooper Discoverer S/T Maxx All-Season LT275/65R20 126/123Q Tire - FRAM Extra Guard CA10261 Replacement Engine Air Filter for 2007-2022 Dodge Ram 2500-5500 (6.4L & 6.7L), Provides Up to 12 Months or 12,000 Miles Filter Protection - Mopar Engine Oil Filter - 5083285AA --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/248694232-cooper-discoverer-s-t-maxx-all-season-lt275-65r20-126](https://www.desertcart.jp/products/248694232-cooper-discoverer-s-t-maxx-all-season-lt275-65r20-126) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-15*
