Load capacity
The markings 91V are the load index and the speed rating, or the service description. The load index (91) is the assigned numerical value for the tire size to compare relative load carrying capabilities.What does load index 91 mean?
E.g., tire size designation: 205/60R15 91V - 91V in "service description" means this tyre can carry maximum load of 615 kg/1356 lb(load index is 91) and it sustains the maximum speed of 240 kmph/149 mph(speed index is V).
What does 93 mean on a tire?
In our example, the "93" stands for the maximum-load rating of 1433 pounds. 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).
What does 92 on a tire mean?
The 92 represents the maximum load the car can carry. The range of load ratings is vast and each number corresponds to a chart that shows how many pounds a single tire can carry. In this case, the 92 means it can support 1,389 pounds.
What does 95 mean on a tire?
Lastly, you've got “95H,” which corresponds to the load index and speed rating for the tire. The load index, or 95, shows you how much weight the tire can handle when inflated the right way. This will fall in a range between 75 and 105 for passenger vehicles.

What does 97 mean on a tire?
A load index of 97 means it can support 1609 pounds. Speed Rating – This indicates the maximum speed at which this tire can be driven on when properly installed. In our example we have a speed rating of 'S' which equates to a maximum speed of 112 mph (or 180 kmh).
What does 96 mean on a tire?
The number is the load index. The higher the number, the more weight the tires can handle. In this case, "96" means the tire can handle 1,565 pounds, while the "Y" indicates the tire is rated to be safe at speeds up to 186 miles per hour.
What does 91w XL mean on a tire?
Some vehicles are equipped with "XL" tires. It doesn't mean that they're extra large, but it does mean that they are extra-load tires. The load index on these tires is much higher than a standard-load tire, which is why it is important to replace an XL tire with another XL tire.
What does 100s mean on a tire?
Just after the tire size are some more numbers, commonly 100T. The 100 is the tire's load index, and in the case of 100, it means by itself a properly inflated tire can hold up 800 kilograms (1,764 lb.).
How do you read a tire code?
How to read your tires codes
- “215” represents the width of the tire from sidewall to sidewall. The larger the number, the wider the tire.
- “60” is the aspect ratio. This is the official sidewall height shown as a percentage of section width.
- “R” is the radial construction.
What's the best speed rating for tires?
As manufacturers developed bigger and better tires, it became necessary to regulate performance at standardized speeds to ensure safety. The "Limited V" category of 250 km/h (149 mph) was then created, and eventually the "Z" speed rating was added as the top speed rating.
Is higher load index better?
If you're thinking about up-sizing, you can switch to a tire with a higher load index, because that means your tire can safely carry more weight, but you can never go down.
What load rating do I need?
To roughly determine the load range capacity for each individual tire, take the vehicle's gross weight and divide by four. If the vehicle gross weight is 4,500 pounds, each tire should be able to safely support at least 1,125 pounds.
What ply is a 117T tire?
275/55R20 Nitto Ridge Grappler 117T XL/4 Ply Tire.
What speed rating is W?
A relatively new addition to the speed rating chart, tires with speed rating “W” can achieve a maximum sustained speed of 168 mph (270 kph).
What's the difference between 95y and 95w?
95 is like 1500lb load rating per tire. W is 168mph roll rate limit Y is 186mph. For the 45 you should consider higher rating tires like the Michelin PSS or similar.
Can I use W rated tires instead of V?
V means that vehicles can safely use the tire with a top speed higher than 149mph. The rating W shows that the tire is safe to use for a vehicle with a top speed of 168mph.
What is the 275 on tires?
The numbers in the tire size refer to its width, aspect ratio, and wheel diameter. "275/35R19" means the tire is 275 mm wide, has an aspect ratio (that is, the width divided by the height) of 35%, and fits on a 19" wheel.
What does 112 mean on a tire?
The numeric load index code 112 represents the maximum load carrying capacity for single wheel use and 109 represents maximum load carrying capacity for the dual wheel use. The first number 112 denotes a tire's ability to carry approximately 2,470 lb (1120 kg).
Does tire speed rating 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.
What does R mean on a tire?
This is indicated in percentage of the tire width. “R” stands for the construction method of the tire indicating the tire is a radial tire. The following two numbers (16) indicate the diameter of the wheel rim in inches. The next two or three numbers (94) indicate the load index of the tire.
What does XL mean on a tire?
XL (or Reinforced) tyres are 'extra load' tyres – they indicate that a tyre is reinforced to be able to withstand a higher load than other tyres of the same size.
What tire codes mean?
As an example, if a tire size has two sets of numbers (6-12, 5.00-15, 11.2-24), then the first number (5.00-15) is the approximate width in inches, and the second number (5.00-15) is the rim diameter in inches. If a tire size has three sets of numbers (15x6. 00-6, 26x12.
