Speed Rating: More Than Just Speed?

Here is a question I recently received in one of the BMW forums I moderate: "Speed rating is just about speed, right? I bought Continental ExtremeWinterContact 225/45-17 tires and I can't believe how they messed up my handling. My previous set of Vredestein winter tires were much better for the general handling. These tires are incredibly flexible, way too soft. They make the car wander about all the time. I played with different pressure; no difference."

Technically, speed rating is only a measure of the tire's top speed capability. However, there is almost always a correlation between handling and speed rating since higher performance tires tend to be capable of maintaining higher top speeds for a longer period of time. While this is not always true, in the majority of cases lower speed rated tires tend to have slower steering responses and reduced dry grip, especially in winter / snow tires.

Shown below is what each speed rating letter equates to in miles per hour: 

  L 75 mph 120 km/h Off-Road & Light Truck Tires
  M 81 mph 130 km/h  
  N 87 mph 140km/h Temporary Spare Tires
  P 93 mph 150 km/h  
  Q 99 mph 160 km/h Studless & Studdable Winter Tires
  R 106 mph 170 km/h H.D. Light Truck Tires
  S 112 mph 180 km/h Family Sedans & Vans
  T 118 mph 190 km/h Family Sedans & Vans
  U 124 mph 200 km/h  
  H 130 mph 210 km/h Sport Sedans & Coupes
  V 149 mph 240 km/h Sport Sedans, Coupes & Sports Cars
  W 168 mph 270 km/h Exotic Sports Cars
  Y 186 mph 300 km/h Exotic Sports Cars

will a t rated tire run soother and quieter than an h rated tire?

Pete, Typically, yes. The sidewall on a T rated tire will be softer compared to an H, so it has the ability to absorb impacts better.

I am considering purchasing (4) Pirelli Cinturato P7 All Season PLus tires for my 2007 Lexus ES 350.
These come in both H- and V-speed ratings. Which option would I be better off buying and why?
Thanks in advance! (:

My 2014 Acura RDX has V rated tires as OEM, should I stick with this or choose an H rated tire for a bit more comfort?

The H speed rated tire does ride a slight bit softer then a V. If you have a choice in the same tire then go with H, if the highest rated tire for ride only comes in V then I would go with that over the speed rating. Back to back most people would not be able to tell the difference they are so close in feel.

Will I notice a ride comfort difference between H and V speed rated tires for my Volvo V60 18 tires? The OEM designation is H, but there are several replacement tires that I like that are V rated.

Also, overall performance difference if I step up to an Ultra High Performance tire?

Thank you.

I do not think most people could tell the difference in ride between an H or a V speed rated tire so if the tire you want is only available in the V speed rating I wouldn’t hesitate going with it. Ultra High Performance tires will generally be higher speed rated like W or Y and you would feel a little firmer ride and more responsive handling and more traction with less tread life compared to a grand touring tire in the H or V speed rating.
