How to Read the Sidewall Letters of a Tire

The sidewall letters of a Tire will tell you several things, including its size and type of tyres reading. They will also tell you about the safety standards of the tire. For example, “LT” before the tire size indicates a light truck tire. If there is no letter prefixed to the size, the tire is a European metric tire. You can use this information to find out what size to purchase for your car. The following are some tips to help you read the sidewall letters of a tire.
Tire’s section width

The section width of a tire is its overall width. It measures the width of the sidewall, from the inner to outer section, when mounted on a vehicle. The lower the number, the narrower the tire. The sidewall is also measured as aspect ratio, or section height. The lower the aspect ratio, the better the sidewall is for steering response and overall handling. To get the most out of your tires, know their aspect ratios and consider how these numbers may affect your purchase.

The section width of a tire is defined by its width on the rim, or wheel, it is mounted on. A tire that is mounted on a narrower rim will have a wider section width than one that is mounted on a wider rim. In general, a smaller-than-average aspect ratio will have a narrower section width. When shopping for new tires, be sure to shop around, as the section width can vary significantly.
Tire’s aspect ratio

The aspect ratio of a tire is a percentage of its width. In a tire, this means that the sidewall of the tire is 65 percent higher than its width. For example, if the tire has a width of 215 mm, its aspect ratio is 65 percent, which gives the sidewall a height of 5.5 inches. This ratio is used to determine the overall performance of a tire. In order to determine the aspect ratio of your tire, you can look for the D designation.

The higher the aspect ratio, the more visible the sidewall. This can have aesthetic effects, but in mud, the extra rubber along the sidewall helps traction. The lower the aspect ratio, the more the tire blends into the rims. However, a higher aspect ratio is better for off-roading. A high aspect ratio will not blend into the rim and will have a better traction in mud.
Load index

You can read the load index for tyres by looking at the placard on the side of your vehicle. These placards will tell you how much weight the tyre can handle when inflated. A higher load index number means the tyre can support more weight. Depending on the type of vehicle, load index values may range from 75 to 100 pounds. The chart below illustrates how to interpret the load index for your tyres.

When choosing a tyre for your vehicle, you need to know the load index. This number is listed next to the speed rating and the diameter. It is important that you buy tyres with the same load index so that the weight is evenly distributed. You can also look up the load index on your vehicle owner’s manual. A load index of 70 means the tyre can support the same weight as a 100-pound object.
DOT code

What is the DOT code for Tyres? This code is found on the sidewall of a tire and tells the manufacturer the date and week of manufacture. For instance, DOT code 017 means the first week of January 1987. It also indicates the speed rating and load index of the tire. If the code is missing, you can look for the code on the other side of the tire. If it is present, the DOT code is a valid indication of the age of the tire.

The DOT code is a three digit number found on the sidewall of a tire. It tells the manufacturer the year it was manufactured and the size of the tire. You can also look up the year the tire was made by looking at the payments. However, it is important to note that there are times when a tire may not be new. Therefore, you should check the DOT code of your tire before buying it.
