Royal Black Racing Trac 255/45R18

The Royal Black Racing Trac is a high-performance all-season tire sized 255/45R18 for light trucks, vans and SUVs. It carries a 103 load index and W speed rating for sustained speeds up to 168 mph. The XL load range supports heavier vehicle weights.

All-season traction limits

The UTQG traction grade A indicates strong wet-road grip, while the M+S designation confirms mud and snow capability. As an all-season compound, it balances year-round use but cannot match dedicated winter tires in severe ice or deep snow conditions.

Load capacity and tread headroom

Load index 103 provides a maximum load per tire suitable for typical SUV and light-truck duties. The 420 treadwear rating suggests moderate longevity, while the 7/32 tread depth offers initial grip that will diminish with wear, eventually reducing wet and snow performance.
