235/55R18 104W XL High Performance All-Season Tire
The Royal Black Racing Trac is a high performance all-season tire built for SUVs and light trucks. It carries a 104 load index and a W speed rating approved for speeds up to 168 mph. The 235/55R18 size fits 18 inch rims and features a black sidewall.
Replaces worn original equipment on SUVs
Drivers gain the XL load range for heavier hauling and the W rating for sustained highway speed. The jump is worth it when the factory tires lack the 420 AA UTQG grades for traction and treadwear. It is not for buyers who need a dedicated winter compound or a run-flat design.
18 inch rim diameter and 28.2 inch overall diameter
The tire mounts on an 18 inch wheel and measures 28.2 inches tall when inflated. The 235 mm section width and 55 aspect ratio set the contact patch and sidewall height. Clearance must be verified against the vehicle specification before fitting.

Questions about this item
Will this 235/55R18 tire fit my 18-inch rim?
Yes, the tire is built for an 18-inch rim diameter. The 235 mm section width and 55 aspect ratio match the size designation, and the overall diameter measures 28.2 inches when mounted and inflated.
What is the correct way to mount this directional high-performance tire?
Mount the tire so the sidewall rotation arrow points forward when the vehicle moves ahead. The common error is installing one tire backward, which reduces wet traction and increases noise.
When should I replace these tires based on the original 7/32-inch tread depth?
Replace them when the tread wears down to 2/32 inch, the legal minimum in most regions. The UTQG treadwear rating of 420 indicates a moderate wear rate, so inspect depth regularly with a gauge.
