AMP Terrain Attack A/T A Tires - 305/40R22

The AMP Terrain Attack A/T A 305/40R22 is an all-terrain tire for a truck or SUV that needs confident dirt-road grip without giving up a comfortable everyday drive. This extra-load configuration has a 13.9/32-inch listed tread depth and a maximum load rating of 2601 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

Extra Load (XL) describes this tire's load classification. Its 114S service description combines a load index with a speed symbol. This specific tire is listed for a maximum load of 2601 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

The multi-block pattern puts more tread edges to work across pavement, gravel and loose dirt. Staggered shoulder blocks find purchase in sand and debris, while stepped blocks move water and mud away from the contact area. It is a practical choice for mixed road and trail use, including changing weather and light snow rather than dedicated winter-tire duty.

AMP balances an aggressive profile with a more controlled road feel than a full mud-terrain. Dual-variation sidewall lugs add edges at the shoulder, and the stepped, open areas help the tire clear loose material as the wheel turns. The result is a tire that looks at home on a built truck and remains useful for daily miles.

What This Size Means for Your Build

This metric size uses a 305 mm nominal section width and 40-series aspect ratio for a 22-inch wheel. Check the wheel width and vehicle clearance before choosing a different size from your factory tire. The listed section width is 12.32 inches, and the tire weighs approximately 48.42 pounds.

Tread Life and Warranty

AMP lists a 40,000-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 305/40R22 and its extra-load 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 A/T A 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.
