While a Z-speed rating still often appears in the tire size designation of these tires, such as 225/50ZR16 91W, the Z in the size signifies a maximum speed capability in excess of 149 mph, 240 km/h; the W in the service description indicates the tire's 168 mph, 270 km/h maximum speed.
Truck winter/snow tires are specifically designed for pickups and SUVs. Like car winter/snow tires, always use truck winter/snow tires in a set of four for optimum grip to go, stop, and corner.
Load and Speed Ratings Every tire has a speed rating and a load rating. The speed rating gives the max speed the tire is built for while the load rating represents the max weight of the automobile. In most cases, even the most basic tires have a speed rating around 118 miles per hour and a load rating that suits most vehicles.
100,000+ drivers and over 2.4 billion miles of data for more than 400 different tire models. That's enough experience combined to help pinpoint the tire that's right for you. And consumer reviews? Tons.

To help you in buying tires, NHTSA has rated more than 2,400 tire lines, including most used on passenger cars, minivans, SUVs and light pickup trucks. The Uniform Tire Quality Grading System (UTQGS) lets you compare tire treadwear, traction performance, and temperature resistance.
Treadwear: This is the wear rate of the tire, comparable only to other tires within a tire manufacturer’s line. 100 is the baseline grade. Therefore a tire with 200 would theoretically last twice as long on the government’s course compared to a tire with 100.
New automotive tires frequently have ratings for traction, treadwear, and temperature resistance (collectively known as The Uniform Tire Quality Grade (UTQG) ratings). Most tires sizes are given using the ISO Metric sizing system.
Tire ratings were developed by the National Highway Traffic Safety Administration (part of the Department of Transportation) purposes of safety, fuel economy, measuring tire durability, and developing tire speed ratings.
