What is the meaning of 205 55 R16 91V?
As an example, for a tyre with the markings 205/55/R16/ 91V, 205 denotes the width of the tyre in millimetres, 55 denotes the tyre’s aspect ratio, which is the sidewall’s height given as a percentage of the width, R16 specifies that it is a radial tyre with an inside diameter of 16 inches and 91V indicates the load . Below is an example of a the description on a tire’s sidewall: 2015/60R15 91V. Here, the tire would have a speed rating of V. V-rated tires can be driven at 149 MPH.The V in the tyre designation 205 55 R16 91V represents the speed rating of the tyre. In this case, the V indicates that the tyre is rated for a maximum speed of 240 km/h or 149 mph under optimal conditions.The first number (205) tells you the width of the tyre in millimetres. The second number (55) tells you the height of the tyre as a percentage of the width. The letter (R) stands for “Radial” which is the type of tyre. The number (16) tells you the size of the wheel rim in inches.In this case, the V indicates that the tyre is rated for a maximum speed of 240 km/h or 149 mph under optimal conditions.This tells you the maximum speed the tyre is suitable for. This is the fourth and final part of your WhatTyre tyre search. Most car tyres for road use have a maximum speed between 118mph (T) and 187mph (Y). Therefore, our example tyre has a maximum speed of 150mph as it has the speed rating V.
What is the tyre pressure for 205 55 R16 91V?
How much tyre pressure for 205/55 r16 tyres. Properly inflated tyres are essential for safe driving. Correct, average 16” front and rear axle tyre pressure should be between 2. Bar and between 2. Bar respectively. While you should always stay within this range, you should also never be below 20 psi, or over 50 psi, or you risk serious tire damage (more so than with standard overinflated or underinflated tires to a lesser degree). Your car may have different ideal tire pressures for the front and rear axles.While you should always stay within this range, you should also never be below 20 PSI, or over 50 PSI, or you risk serious tire damage (more so than with standard overinflated or underinflated tires to a lesser degree).No, for most cars a tire pressure of 40 psi is too high. You might find 40 psi suitable for some vehicles, especially if they’re carrying heavier loads or if the manufacturer’s recommendation is close to that figure. However, it’s generally too high for most passenger cars, which usually recommend between 30-35 psi.Running your tires at the correct pressure is important because it keeps you safe, cuts down your gas bill, and makes your tires last longer. Each vehicle has its own specifications for tire pressure, but most fall between 28 and 36 PSI (pounds per square inch).
What does the V stand for on a tyre designated 205 55 R16 91V?
The V in the tyre designation 205 55 R16 91V represents the speed rating of the tyre. In this case, the V indicates that the tyre is rated for a maximum speed of 240 km/h or 149 mph under optimal conditions. Load index. The H/V is the speed rating. Max speed for H is 130mph, V is 149mph. These ratings degrade as the tire degrade. The load rating means the 91 can take a load of 1354lbs and 94 is 1477lbs per tire.Speed rating corresponds to the maximum speed that a tire can sustain when it is carrying the recommended load capacity. The rating system uses letters from A to Z. Here, you can see that a tire with a 91V mark can them run at a maximum speed of 149 mph while carrying 615 kilograms or 1,356 pounds load.These two speed ratings are most frequently made for performance tires, but which one is better? The main difference between 91V vs 91H tires is definitely speed. H speed-rated tires have a capability of 130 mph, while the V has a maximum speed of 149 mph.H-rated tires only allow you to rev up within a maximum range of 130 mph. In comparison, V-rated ones extend the performance of tires up to 149 mph. The distinction comes from the theoretical aspect of speed and the driving experience. One thing is certain: swapping the two is not good for the vehicle or the driver.
What is the speed limit on a 91V tire?
For example, a tyre marked “205/55R16 91V” has a speed rating of “V,” which means it can safely maintain speeds up to 240 km/h (149 mph). The H/V is the speed rating. Max speed for H is 130mph, V is 149mph. These ratings degrade as the tire degrade. The load rating means the 91 can take a load of 1354lbs and 94 is 1477lbs per tire.H-rated tires only allow you to rev up within a maximum range of 130 mph. In comparison, V-rated ones extend the performance of tires up to 149 mph. The distinction comes from the theoretical aspect of speed and the driving experience.No, you should NEVER do this. Using a tyre with too low a speed rating for the car increases the risk of tyre failure at high speeds. Also, doing this can potentially invalidate your insurance.For example, a tyre that reads 255/40 R20 101V shows V to be the tyre speed rating. The tyre speed rating chart below shows that V corresponds to 149 mph. Therefore, tyres with this speed rating should not be driven over 149mph.
What size tire is a 205 55R16 91V?
R16 tires have a diameter of 24. The sidewall of the tire is 4. When discussing winter tire performance, a tire size such as 205/55R16 provides several advantages: Improved Traction: A wider tire provides better traction on slippery road surfaces. The extra width gives you better control when driving on snow and ice.Similarly, we only recommend changing the aspect ratio by 5% either side of your cars preferred size. For example, a car designed to take a 60 aspect ratio tire could also fit a 55 or 65 aspect ratio. In winter it is very common to ‘downsize’ tires – this is making the width slightly smaller.It’s highly recommended to use the exact tire size recommended for your car. However, in a pinch the tire width and aspect ratio can be changed slightly and still fit on your rim. Although this will still work, keep in mind it may have adverse effects on the performance of your car.For example, a narrow tire will have less wind resistance, rolling resistance, and weight, thus, increasing gas mileage. If choosing a narrower tire, be aware that they can make the car’s handling characteristics more difficult to control.
What is the 91V spec on a tire?
This index is a combination of a number followed by a letter. For instance, the index “91V” indicates a maximum speed of 240km/h (based on a table), and the letter “V” is an alphabetical index, by which A indicates the lowest and Y the highest speed class. The load range of 94 holds a couple more pounds than the load range 93. That is the only difference.A: 94 is the load capacity meaning it can safely carry a load of 1477 lbs. V and H is the speed rating. H= 130 mph while V= 149 mph. JP.
