What this tire speed rating ensures is that the tire can sustain the maximum speed specified for an indefinite duration. This means that a tire with a V-rating, for example, can be driven at 149 miles per hour until it wears out!
similarly, Should I get H or V rated tires?
To support running at higher speeds, V-rated tires will have a stiffer sidewall and slightly firmer ride than H-rated tires. For normal driving conditions the H-rated tire will provide a more comfortable ride and the V-rated should give slightly better handling.
on the other hand, Can I use 235 tires instead of 225?
Are 225 and 235 Tires Interchangeable? Yes, they are. However, this is only possible if your car’s rims can accept the larger millimeter.

Can I put a higher speed rated tire on my car?
Experts frown on the practice of mixing and matching lower and higher speed-rated tires on one vehicle. It can lessen your car’s ability to handle wet road conditions. Additionally, your maximum mph will be based on the lowest speed-rated tire you have.
Can I mix V and W rated Tyres?
You can invalidate your car insurance by fitting new tyres that have a lower speed rating than the manufacturer’s original fit. … Mixing tyre speed ratings isn’t recommended.
Can I mix H and V-rated tires?

Can I use 235 55r17 instead of 225 65r17?
Yes. For safety reasons be sure that the replacement tires are rated for both load and speed at or above the specifications for your Vehicle. Be sure to replace the tires in pairs on either the front or rear axles. Failure to do so could cause problems.
Can I use 225 55r17 instead of 225 65r17?
The difference in the dimension of the two tyres is purely in the aspect ratio of the sidewall so the /65 tyres will have a bigger sidewall (note that the number is 65% of the width, not 65 somethings – i.e. 165.75mm vs 140.25mm and that’s effectively doubled because you’re taking radius, not diameter) and therefore …
What does the 235 mean on a tire?
The number 235 is the cross-section width in millimeters, while 70 is the ratio of sidewall height to cross-section width (70 percent). R means radial-ply construction and 16 is the wheel diameter, in inches.
Are wider tires better?
Advantages. Larger tires improve handling and cornering, due to wider tread faces and stiffer sidewalls. Wider tires may decrease braking distances on dry pavement. Wider tires may also increase acceleration, especially in very powerful vehicles such as muscle cars.
What does 91H mean on a tire?
The 91H and 91T refer to the tire Load bearing index and speed rating of the tire. (Load Index 91 refers to 1356 Pounds or 615 Kilograms). Typically, the load indexes of the tires used on passenger cars and light trucks range from 70 to 110. The H and T refer to the speed rating of the tire.
Does higher speed rating mean better tire?
The speed rating tells you the speed the tire can safely maintain over time. A higher speed rating usually means you will have better control and handling at higher speeds – and that the tire can take the extra heat. As a general rule, tires with higher speed ratings also handle better at slower speeds.
Should all 4 tires have same speed rating?
In general, all tires on the vehicle should be the same speed rating and replacement tires should have a speed rating equal to or greater than the speed rating of the OE tires.” “Tires with different speed ratings may vary in ride, handling and/or other performance characteristics.
What happens if you go over tire speed rating?
Safety advocates and tire experts say that habitually driving faster than a tire’s rated speed can generate excessive heat that damages the rubber, with potentially catastrophic results. … Tires were a factor in 198 of those crashes and 223 deaths.
What is the difference between Y and W speed rating?
Speed ratings are achieved through tests performed by engineers who run the tyre at 6.2 mph steps, in 10 minute increments, until the required speed has been met. … Confusingly, W-rated tyres are rated at a higher speed in excess of 168mph. Y-rated tyres are rated in excess of 186mph.
Is a higher tire speed rating better?
The speed rating tells you the speed the tire can safely maintain over time. A higher speed rating usually means you will have better control and handling at higher speeds – and that the tire can take the extra heat. As a general rule, tires with higher speed ratings also handle better at slower speeds.
Do all 4 tyres need to be the same speed rating?
For optimal safety and performance, we recommend fitting the same tyres to every wheel position on your car, so you should have the same brand, size, tread pattern, load index and speed rating on the front and rear tyres.
Do all 4 Tyres need to be the same speed rating?
For optimal safety and performance, we recommend fitting the same tyres to every wheel position on your car, so you should have the same brand, size, tread pattern, load index and speed rating on the front and rear tyres.
Do tire speed ratings need to match?
If you’re replacing tires and think you may want a lower- or higher-speed-rated tire, it’s best not to mix and match. … Get tires with the same speed rating. If you don’t, remember that the maximum mph is limited to the tire with the lowest speed rating.
Will 235 65R17 fit 225 60R17?
Not safely, no. If you go to a narrower tread width tire you will want to increase the sidewall height aspect ratio exponentially. The shorter sidewall 225/60R17 tire will not provide the needed load carrying capability needed for your vehicle.
Can you put different size tires on rims?
Wheels and tires are not interchangeable words. … For instance, your vehicle has a set size of rims, but you can buy different sizes of tires to fit those rims, as long as the middle of the tires is the correct size. That being said, a vehicle with bigger rims will often be able to fit larger tires than other vehicles.
What size tire is 225 65R17?
This number means that your tire has an aspect ratio of 65%. In other words, your tire’s sidewall height (from the edge of the rim to the tire’s tread) is 65% of the width. In this case, the sidewall height works out to be 146 millimeters. The tire size was designed to fit rims or wheels that are 17 inches in diameter.
