High Performance All Season Tire

The Royal Black Racing Trac is a high performance all season tire built for SUVs and light trucks. It fits an 18 inch rim with a 255 millimetre section width and a 50 series aspect ratio. The 106 load index and XL load range support heavier vehicle demands.

Sustained Load Behaviour

The 420 treadwear rating indicates the compound resists wear during extended daily driving rather than only short bursts. UTQG traction grade A shows consistent wet grip over the tyre's life. The 7/32 inch tread depth provides a usable starting point for long term mileage.

Practical Limits of the Standard

Speed rating V certifies the tyre for sustained speeds up to 149 mph under its maximum load. The overall diameter of 28 inches must match the vehicle's gearing and clearance specifications. Run flat capability is not included so a puncture requires immediate repair or replacement.

Questions about this item

How much road noise and heat should I expect from the 255/50R18 106V XL tyres during all-day motorway driving?

The UTQG 420AA rating and 7/32 in tread depth indicate a firm compound that runs cooler and quieter than softer high-grip tyres, while the XL reinforced sidewall resists heat build-up under heavy SUV loads.

My SUV has 18-inch rims — is that the only fitment requirement for the 255/50R18 106V XL tyres?

Yes, the tyres are built for an 18 in rim diameter; the 255 mm section width and 50 aspect ratio must also match the wheel well clearance and the vehicle’s recommended load index of 106 or higher.

Will the 255/50R18 106V XL tyres work with the original alloy wheels I am keeping on my older SUV?

Provided those alloys are 18 in diameter with the correct bolt pattern and offset, the tyres will mount and seal normally; the black sidewall and XL load range do not change fitment on standard rims.
