High-performance all-season tire

The Royal Black Racing Trac is a 255/50R20 tyre built for truck and SUV drivers who want responsive handling year-round. It carries a 109 load index and W speed rating in an XL construction for heavier duty use.

UTQG 420AA compound and tread life

A 420AA UTQG rating signals durable treadwear with strong traction and temperature grades. The 7/32 inch tread depth and black sidewall design support consistent grip and even wear during daily driving.

XL construction for sustained loads

Extra-load reinforcement keeps the tyre stable under continuous highway speeds and full vehicle payloads. Run-flat capability is not included, so pressure monitoring remains essential for long-distance journeys.

Questions about this item

How do I mount this 255/50R20 tire on a 20-inch rim and what step is often missed?

Mount the tire on a 20-inch wheel with the black sidewall facing outward, then inflate to the vehicle manufacturer's pressure specification — not the maximum pressure molded on the sidewall.

When will this tire need replacement based on its 7/32 tread depth and 420AA UTQG rating?

Replace when tread wears down to 2/32 inch; the 420 treadwear grade suggests moderate wear life, so inspect depth regularly with a gauge.

What is the first limit reached during sustained high-speed driving with a W speed rating and XL load range?

The W speed rating defines the maximum sustained speed capability; exceeding it risks heat buildup and structural failure before the XL load capacity becomes a factor.
