Cooper Discoverer Rugged Trek LT275/65R20 126/123Q MPN 170057007

What would put the Cooper Discoverer Rugged Trek LT275/65R20 126/123Q MPN 170057007 ahead of the Bridgestone Dueler A/T Revo 3 LT255/75R17 111/108R MPN 000018 and the Bridgestone Dueler A/T Revo 3 LT265/60R20 121/118R MPN 000028?

Cooper Discoverer Rugged Trek LT275/65R20 126/123Q MPN 170057007 is recorded as an exact MPN row, so shoppers can compare one tire size instead of a broad family label.

The Cooper Discoverer Rugged Trek LT275/65R20 126/123Q MPN 170057007 and the Bridgestone Dueler A/T Revo 3 LT255/75R17 111/108R MPN 000018 and the Bridgestone Dueler A/T Revo 3 LT265/60R20 121/118R MPN 000028 solve the same wheel & tire clearance need in different ways. This compare holds what each includes, where each stops fitting, and what each asks of the install side by side; price is read after that, on purpose.

Cooper Discoverer Rugged Trek LT275/65R20 126/123Q MPN 170057007 is an exact SimpleTire row promoted into the truck tire catalog for 2024 Chevrolet Silverado 2500 HD LT Crew Cab 4x4 Duramax planning with official tire-family docs and a current seller price snapshot.

Choose it if

  • Cooper Discoverer Rugged Trek LT275/65R20 126/123Q MPN 170057007 is tracked as an exact MPN row, so shoppers can compare one tire size instead of a broad family label.
  • The 2024 Chevrolet Silverado 2500 HD LT Crew Cab 4x4 Duramax route keeps offset, diameter, load, and rim-width checks visible before the offer is treated as a match.
  • Seller price, rating context, warranty resources, exact tire specs, and fitment checks are present, but final stock and shipping terms still belong in checkout.
  • Use these tire rows only when the selected LT size, load range, wheel width, service description, and positive-offset wheel package stay inside the Silverado HD route limits.

Pass if

  • The Cooper Discoverer Rugged Trek LT275/65R20 126/123Q MPN 170057007 is not the right choice when your truck falls outside 2020-current Chevrolet Silverado 2500 HD current Duramax trucks, or its trim, engine, and package cannot be matched to the documented application.
  • Pass when this exclusion applies: Dual-rear-wheel, ZR2, Sierra HD, or aggressive-offset setups without their own route check
  • Choose another size or construction when load capacity, wheel width, offset, rubbing clearance, ride, or spare-tire needs point elsewhere.

Verify

  • Exact tire MPN, tire size, and four-tire price
  • Load range, service description, rim width, and tire diameter
  • Wheel offset, brake clearance, seller stock, shipping, returns, and installer requirements
  • The checked shelf is a 2024 Silverado 2500 HD LT Crew Cab 4x4 Duramax route; GMC Sierra HD, dual-rear-wheel, ZR2, lifted, and heavy commercial setups need their own seller and clearance check.
