All-season high-performance tyre

The Royal Black Racing Trac 235/40R18 95W XL is built for passenger cars that need year-round grip and responsive handling. Its all-season compound and M+S rating suit wet, dry and light snow conditions without a seasonal swap. The W speed rating supports sustained driving up to 168 mph.

XL load range with black sidewall

Extra-load construction carries heavier vehicle loads at the 95 load index while the black side wall gives a clean, stealthy appearance. The 18-inch rim fitment and 25.4-inch overall diameter match many modern sedans and coupes without altering speedometer calibration. Run-flat technology is not included, so a spare or repair kit remains necessary.

Upgrade from standard touring tyres

Drivers moving from basic touring rubber gain sharper turn-in and shorter wet braking distances thanks to the high-performance tread design and UTQG 420AA ratings. The tread depth of 7/32 inch provides measurable wear life for daily commuting. Buyers who need dedicated winter traction or run-flat security should consider other categories.

Questions about this item

What does the W speed rating on the 235/40R18 tire cap the maximum speed at?

The W rating limits the tyre to 168 mph when correctly inflated and loaded within the 95 load index.

What rim diameter and load range are required to mount this 235/40R18 XL tyre?

It fits an 18‑inch rim and carries an XL load range for higher pressure capacity.

How is the Royal Black Racing Trac installed, and which step is often missed?

Mount on an 18‑inch wheel, torque lug nuts to the vehicle spec, then inflate to the placard pressure — skipping the pressure check is the common error.
