AMP Terrain Attack R/T Tires - LT285/55R20

The AMP Terrain Attack R/T LT285/55R20 is a rugged-terrain tire for drivers who want more trail bite than a conventional all-terrain while keeping a composed road ride. This Load Range E configuration has a 16.4/32-inch listed tread depth and a maximum load rating of 3305 / 3000 lb. Those are the details to compare alongside the tire size when choosing a setup for your truck or SUV.

Sold individually: Quantity 1 is one tire, not a set of four.

Understanding This Tire's Load Rating

Load Range E identifies a load and inflation class; the letter is not a literal count of sidewall plies. Its 122/119Q service description combines separate load indexes for single and dual wheel use with a speed symbol. This specific tire is listed for a maximum load of 3305 / 3000 lb; compare that rating with the vehicle's requirements rather than choosing by the load-range letter alone.

How It Drives and Where It Grips

Large, open shoulder blocks work in dirt, gravel and mud, while stone ejectors help stop rocks and packed debris from staying in the grooves. The wider center contact area gives the tire more continuous road contact, a useful balance for a truck that sees both the highway and the trail. On wet or lightly snow-covered roads, the open pattern provides evacuation paths, though this is not a dedicated winter tire.

AMP uses a staggered sidewall for added protection against trail abrasion and offers two distinct sidewall appearances in the R/T design. The wide center patch is intended to soften road noise and support even wear, so the tire has the look and shoulder traction of a serious off-road build without committing to a full mud-terrain pattern.

What This Size Means for Your Build

This LT-metric size uses a 285 mm nominal section width and 55-series aspect ratio for a 20-inch wheel. Check the wheel width and vehicle clearance before choosing a different size from your factory tire. The listed section width is 11.69 inches, and the tire weighs approximately 67.24 pounds.

Tread Life and Warranty

AMP lists a 50,000-mile limited tread life warranty for this tire family. That figure is warranty coverage, not a promise that every tire will last exactly that long; eligibility and maintenance requirements are set by AMP's warranty terms.

Fitment Notes

Match LT285/55R20 and its Load Range E rating to your vehicle's requirements. Check your wheel's approved width, tire clearance, and the vehicle manufacturer's load and speed requirements; size alone does not establish vehicle fitment. Maximum inflation pressure is not a recommended operating pressure. The tire's load rating is not a vehicle payload or towing rating.

Why AMP Tires?

AMP builds tires for trucks that need a confident stance and traction beyond smooth pavement. The Terrain Attack R/T combines its own tread and sidewall approach with sizing options for different wheels, so you can choose the tire that fits how you actually drive.
