M: Maximum Speed – A tire with this rating can run up to 116 miles per hour (or 188 km/h). R — Up to 106 mph. In other words, if a tire is rated “S”, then the tire will perform for an extended period of time at 112 mph and, although it won’t break apart the instant you hit 113 mph, it’s not recommended to sustain speeds higher than 112 mph. The final letter is the speed rating. The speed ratings by letter are outlined below: L = 75mph/120kmh. V vs W Speed Rating. The mileage fall by half if you use different sizes on the rear and front axle. Nowadays, it means 149 mph but. The “W” speed rating denotes that the tire can handle speeds up to 168 mph (270 km/h). These speed ratings provide a more precise indicator of a high performance tire’s speed over 149MPH. ** Per the TR&A 2007 yearbook, for tires having a maximum speed capability above 240 km/h (149 mph), a ZR may appear in the size designation. It features an asymmetrical tread design for optimal control at high speeds on wet and dry. Some tires have speed ratings of W, 168 mph and Y, 186 mph. The “94” denotes the Load Index, indicating the tire can carry a maximum load of 670 kg (1,477 pounds). The reason for this is that car tyres with different speed ratings can have different handling characteristics, which can affect the overall performance and safety of the vehicle. However, H and V also have obvious differences that you need to consider. For example, H falls between U and V, with the common perception that H stood for "high performance" at one time. Some tires have speed ratings of W, 168 mph and Y, 186 mph. More expensive tyres can bear the H rating. When new cars were developed that could exceed this speed, the automotive industry added the W and Y ratings. These exceptional speed ratings are W, 168 mph; (W), 168+ mph; Y, 186 mph. For S-speed-rated tires, it's 112 mph; for T, 118 mph. The speed rating is represented by a letter, and it’s the maximum safe operating speed of the tire. W and Y-speed tires were innovated later as cars got faster with the help of technology. For S-speed-rated tires, it's 112 mph; for T, 118 mph. For example, a tire description 235/45R18 94V means: 235 – Section Width (mm) 60 – Aspect Ratio (tire height divided by width) R – Radial Construction. The most important factor is the maximum speed the tire can deliver. . U 200 km/h.
