Tire Size and Fitment

The Royal Black Racing Trac measures 205/40ZR17 with an overall diameter of 23.5 inches. It fits 17-inch rims and carries a section width of 205 millimetres. The XL load range and load index 84 support heavier passenger-vehicle loads.

Drivers Suited and Not Suited

This all-season high-performance tyre serves sedan and family-car owners who want year-round grip and a W speed rating up to 168 mph. It is not for buyers who need a run-flat design, a dedicated winter compound, or a higher load capacity than index 84 provides.

Deciding Specification: UTQG Treadwear 420

The UTQG treadwear grade of 420 indicates the expected wear rate relative to the reference standard. A higher number suggests longer life; a lower number typically signals softer rubber for more grip. Match this rating to your mileage expectations before purchasing.

Questions about this item

When will the 7/32 inch tread depth on the Royal Black Racing Trac need replacement?

Replace the tire once the tread wears down to the legal minimum of 2/32 inch; the 7/32 inch starting depth gives measurable mileage before that point.

What is the first sustained-use limit of the W-speed-rated 205/40ZR17 tire?

The W rating certifies continuous operation up to 168 mph; exceeding that speed is the primary limit under sustained high-speed driving.

How much heat builds up in the XL-reinforced 420 UTQG tread during all-day running?

The 420 treadwear compound and XL construction are engineered to dissipate heat at highway speeds, keeping temperatures within the W-rating envelope for extended periods.
