Tire for SUVs and Light Trucks

The Royal Black Racing Trac is a high-performance all-season tire built for SUVs, light trucks and vans. It mounts on a 20 inch rim and carries a load index of 105 with an XL load range. The black sidewall finish suits factory or aftermarket wheels. Buyers needing a dedicated winter tire or a run-flat design should look elsewhere.

Speed rating W for 168 mph capability

The W speed rating confirms sustained operation up to 168 mph, making this the single figure that decides fitment for high-speed driving. The 255/45R20 size delivers a 255 mm section width and a 45 percent aspect ratio on a 20 inch diameter wheel. Verify the vehicle placard matches these dimensions before purchase.

UTQG 420 AA traction and wear

UTQG grades of 420 treadwear, A traction and A temperature indicate how the compound behaves under prolonged highway loads rather than short bursts. The 420 rating suggests a balance between mileage and grip. Tread depth measures 7/32 inch from new. The tire is not run-flat and rim is not included.
