Falken’s LT285/55R20 Wildpeak A/T4W combines a 122/119T Load Range E specification with 18/32-inch tread. The 32.6-inch overall diameter and 11.7-inch overall width describe the physical package on the manufacturer’s 9.0-inch measuring rim.
Approved wheel widths run 8.0–10.0 inches. This severe-snow-rated all-terrain has single/dual load limits of 3,305/3,000 lb; POR can help compare the exact service specification with your vehicle and wheel requirements before installation.

Fitment & Installation
Match the complete tire size, load index, speed rating and approved wheel-width range to the vehicle, wheel and intended load. Check body, suspension and brake clearance through steering and suspension travel before mounting. A qualified installer should set cold inflation using the vehicle placard and actual load; the tire maximum is a rated limit, not a daily pressure recommendation. Never exceed vehicle axle or payload ratings. Ply rating describes load strength, not a literal sidewall-ply count. Ask POR to check the complete setup before ordering. Never mix tire sizes, constructions or types on an axle except for temporary spare use. Underinflation or overloading can cause tire failure and serious injury. Changes in overall diameter can affect handling, braking and rollover behavior.
