Tire specification and fitment

The Royal Black Racing Trac is a high-performance all-season tire sized 215/35ZR18 84W XL for passenger cars. It carries a load index of 84 and a W speed rating certified up to 168 mph. The overall diameter measures 23.9 inches with a section width of 215 mm. Black sidewalls complete the fitment.

Mounting notes and common issues

The tire mounts on an 18-inch rim and features an XL load range with a 4-ply rating. Installation follows standard passenger-tire procedures; the rim is not included in the purchase. A frequent issue is confusing the XL marking with a run-flat designation — this model is not run-flat. Verify the 215/35R18 size code against the vehicle placard before fitting.

Sustained driving characteristics

The UTQG rating of 420AA indicates a treadwear grade of 420 and traction grade A. The tread depth starts at 7/32 of an inch. Under continuous highway or spirited driving the compound maintains consistent grip across wet and dry surfaces thanks to the all-season design. The XL construction supports the rated load during extended high-speed runs without excessive heat buildup.

Questions about this item

How do I confirm the tire is performing as intended after installation?

Check that the sidewall shows the 215/35R18 84W XL markings and that the UTQG 420AA rating matches the specification. Verify even tread wear across the 7/32 depth and ensure the speedometer reads correctly at the 168 mph W rating limit.

What comes in the box and what must I buy separately?

The purchase includes the tire only. The rim is not included and must be sourced separately to fit the 18 inch diameter.

Which version should I choose for my vehicle?

Select the 215/35ZR18 84W XL size if your vehicle requires a 215 mm section width, 35 aspect ratio, 18 inch rim diameter, 84 load index and W speed rating for all-season high-performance use.
