When it comes to car maintenance, tires play a vital role. A tiny set of letters and numbers on the sidewall of your tire can make a huge difference in your driving experience. “99v, 99h, 99w, 99t, & 99y”, what do they mean on a tire? Buckle up, folks, because we’re about to embark on a tire-iffic adventure!
What does 99 mean on a tire?
The “99” in all these codes refers to the Load Index of the tire, which is the maximum load the tire can carry when fully inflated. The second letter is the Speed Rating, an indication of the maximum speed at which the tire can carry a load corresponding to its Load Index. These speed ratings range from A (lowest) to Y (highest).

|Very High Speed
