What happens if you exceed the speed rating of a tire?

What happens if you exceed your tire's speed rating? If you drive faster than the rated speed for your tires you are risking damage to the tires that could cause safety and performance problems down the road.

Can you go faster than tire speed rating?

It should! Also remember that the tire speed rating isn't the same thing as a recommended travel speed. The rating will nearly always exceed maximum highway speed limits, but no tire or vehicle manufacturer advises driving faster than the law allows.

Does speed rating on a tire really matter?

One of the most important aspects of any tire is its speed rating. The wrong tires with a less-than-adequate speed rating for your vehicle can cause safety issues, including tire failure and a loss in fuel efficiency.

Can I use V rated tires instead of H?

A V-rated car requires a tire designed to operate to a maximum of 149 mph and can thus not be fitted with an H-rated tire. The speed rating system was developed to control the safe speeds at which tires must still perform as per the intended design.

Can I put a higher speed-rated tire on my car?

SPEED RATINGS REFER TO MORE THAN JUST SPEED

You can always increase the speed rating of the tires on your vehicle for improved performance, but can never decrease it without reducing the vehicle top speed to that of the lower speed rating selected.

What Is A Tire Speed Rating?

Can I use Y rated tires instead of W?

You certainly should feel a difference between those 2 ratings when cornering. The Y speed rated tire will feel stiffer (given the same sidewall height) than the W. It`s not just an issue above 168 mph as some may think. These two speed ratings will feel different across the performance spectrum.

Can I mix H and W rated tyres?

Can I mix speed ratings on my vehicles tyres? If you are going to mix speed ratings, which we don't recommend, make sure the lower rated tyres are on the front axle, regardless of whether your vehicle is front-, rear- or four-wheel drive. This is to prevent a potential oversteer scenario.

Which speed rating is better H or V?

An “H” rated tire is designed to operate at a maximum speed of 130 mph. A “V” rated tire on the other hand is designed to operate at a maximum speed of 149 mph, almost twenty miles an hour more than the “H” rated tire.

What does M's mean on tires?

M+S stands for Mud+Snow, indicating that the tires are suitable for use in the winter (studded or non-studded winter tires). The official winter tire marking is the snowflake symbol, also known as the 3PMSF marking.

What does W mean on tires?

The letter W denotes the maximum speed rating, which translates 168 mph—not something intended for mom's minivan. See our list of speed ratings below, which range from a low of "L" (just 75 mph for some off-road tires) to a high of Y (186 mph).

How fast can you go with tires?

You should not drive over 50 mph and no more than 50 miles with a donut-type spare tire. Driving for long distances on a spare tire can potentially cause damage to other car parts, including the transmission.

Can I use ZR tires instead of R?

R indicates that the structure is RADIAL. So, VR indicates that the tyre has a RADIAL structure and a speed index equal to V. There is therefore no difference between a ZR or an R tyre with the same speed index.

What does XL mean on a tire?

XL tyres have been especially developed for use with heavy loads. Generally speaking, the tyre name XL is used for heavy duty tyres. However, the labelling varies between tyre manufacturers. Sometimes you might have XL tyres that are also labelled "reinforced" (RF or RFD), or models labelled EL (Extra Load).

Do m/s tires have snowflake?

"M+S" generally means Mud and Snow for All-Season tires

So even if a tire has a “M+S” marking, it can only be considered a true winter tire if it also has the Three Peak Mountain Snowflake symbol. On the other hand, all winter tires carry the “M+S” mark.

Is 3PMSF better than m s?

Compared to M+S tyres, 3PMSF winter tyres offer superior braking and cornering performance on wet and rough ice, soft and hard-packed snow, and slush. A tyre without the 3MPSF marking cannot be marketed as a snow tyre or a winter tyre.

Are M S tires OK for Coquihalla?

She says nine of ten extended closures last winter on the Coquihalla involved commercial trucks. Appropriate winter tires have either the M+S or mountain/snowflake symbol in good condition, and a minimum tread depth of 3.5 millimeters.

Can I use a tyre with a higher load rating?

Is it possible to fit tyres with a higher load index and a lower speed rating than my manufacturer recommends? Yes, you can fit tyres that have a higher load index and a lower speed rating.

Can I put XL tyres on my car?

Their Use. Naturally, most people think that these tyres are designed for use on large vehicles like tractors, buses or lorries. However, it is not the case. Your everyday SUV, CUV or light commercial vehicle can also be fitted with XL tyres.

What does V mean on a tire?

V - Speed ratings are represented by letters ranging from A to Z. Each letter coincides to the maximum speed a tire can sustain under its recommended load capacity. For instance, V is equivalent to a maximum speed of 149 mph.

Are XL tires heavier?

The XL refers to the weight of the car itself. Standard tyres of various sizes have recommended vehicle weights that they can carry. These tyres are marked SL. XL tyres by contrast, tend to be fitted on high end family saloons, performance cars, 4X4s, SUVs and so on - because these vehicles tend to be heavier.

What is the difference between Zr and R tires?

ZR tires were historically known as “performance-rated tires” with a speed rating of more than 149 mph while the letter R on a tire represents both the fact that it is built with a radial construction in mind and the fact that it is speed rated for 106mph.

What does RZ mean on tires?

ZR basically means the tyre is adapted for speeds above 149 mph. ZR tyres includes the speed ratings V(149mph), W(168mph) and Y(186mph). Before 1990, the manufacturers used "ZR" to mean high performance tyres before the ratings got refined with W, Y…

How fast can a ZR tire go?

ZR Designation

Tires having a maximum speed capability over 149 MPH may have “ZR” in the size designation. Tires with a maximum speed capability over 186 MPH are required to include “ZR” in the designation. Below are examples of tire sizes with a “ZR” speed rating.

Why do spare tires have a max speed?

But because the spare is smaller than the opposing wheel on the same axle, it must turn faster to keep up with the speed of the car, making the differential work to account for the variation. It's as if the car is constantly in a turn.
