Where is the speed rating located on a tire?
You can find a tire’s speed rating on the sidewall, where one will typically see a string of numbers and letters. These are several important codes, such as radial construction, aspect ratio, tire load and speed rating. The speed rating is typically the last letter listed on the sidewall (coming after the load index, which is a number).
What do the letters mean?
Speed ratings go from A1 to Y, with A1 having the lowest rating and Y being the highest, but there are some anomalies. There are eight different A ratings. There are no X, O, or I ratings, and H rating is in the “wrong” place. Also, the ZR rating isn’t truly its own rating, but includes both W- and Y-rated tires.

DETERMINING TIRE SPEED RATING
Speed ratings are the product of laboratory testing – with simulated speeds and loads. To receive any kind of rating, a tire must demonstrate that it’s capable of sustaining a particular speed. Industry standards govern the process of reaching and maintaining a given speed during a test.
TIRE SPEED RATING SYSTEM QUIRKS AND ANOMALIES
Today’s speed rating system uses letters A through Z. Each letter corresponds to a specific speed. In general, that speed goes up as the rating advances alphabetically. For example, a tire rated “L” is good for a lower maximum sustained speed than one rated “N.”

Service Rating: 91V vs. 91H
WRX is supposed to have a tire with service rating of 91V. I'm looking at two same Dunlops, one with a 91H and one with a 91V service rating. Would this just mean the difference between H & V speed rating? And, if so, would that likely just mean that the H rating has a slightly softer sidewall? If you know, please let me know.
