Falken Wildpeak A/T4W 305/55R20 Tire
The 305/55R20 Wildpeak A/T4W provides a broad 12.4-inch catalog overall width and 33.2-inch diameter in a 116T standard-load specification. Falken’s all-terrain tread gives this 20-inch option a technical road-and-trail focus with severe-snow certification.
Wheel selection is especially important here: the manufacturer approves 8.5–11.0-inch widths and uses a 9.5-inch measuring rim. Account for 57.5 lb approximate tire weight and full steering-travel clearance when comparing the package with your current tires.

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.
