It's a speed rating, in this case meaning 'up to 130 mph'.
In a tire with metric sizing, on an example of 120/70ZR17: 120=tire width in millimeters 70=aspect ratio Z=speed rating R=construction type 17=rim diameter in inches In a tire with alpha numeric sizing, on an example of MT90H16: M=motorcycle use T=tire width code 90=aspect ratio H=speed rating 16=rim diameter
rating pending means that the esrb is still deciding on the rating

AnswerThe W in 91W after the size code indicates a speed rating. While these tires are proably Z rated (speeds in excess of 149MPH) in the tire size the W indicates that the tires are rated to a higher speed. W and X were added since there were no guidelines about how much over 149 Z rated tires were good for.W indicates a top rated speed of 168MPH._____The "91" indicates load capacity per tire! You'll get about 1350lbs per tire.:)
In modern tire sizing, the 88V at the end refers to it's load and speed rating. The '88' means it has a load capacity of 1,235 pounds and the 'V' is for 149 miles per hour (or 240 km, per hour). - This sounds like a tire for a large fast SUV.

In tire specifications, the "88h" and "88s" refer to the load index and speed rating of the tire, respectively. The "88" indicates the maximum load capacity the tire can support, which is approximately 1,235 pounds (560 kg) per tire. The letter "H" signifies a speed rating of up to 130 mph (210 km/h), while "S" indicates a speed rating of up to 112 mph (180 km/h). These ratings help ensure that the tire is suitable for the vehicle's performance and load requirements.
A ''Z'' tire means that the top speed rating of the tire is not designated, and you must consult the manufacturer to obtain the rating. A ''W (ZR)'' tire's top speed rating is 270 km/h or 168MPH. A ''Y (ZR)'' tire's top speed rating is 300 km/h or 186 MPH. A ''ZR'' tire is rated at top speed of 300 km/h or 186 MPH, AND ABOVE. No, ''Z'' tires, and ''ZR'' tires are not the same.
