What Kind Of Tires Do I Need – Tires come in a variety of inner diameters, typically ranging from 13 to 22 inches. The tire size you need depends on the make and model of your car. Tire size must match the size of the rim and can affect the ideal pressure inside your car, so knowing your tire size is an important part of properly maintaining your vehicle.
If you’re looking for new tires, the first thing to do is check the size of your current tires. Simply check the tire placard on the driver’s side front door sill or glove box, in your owner’s manual, or on the sidewalls of your tires to find a series of numbers and symbols that should look like this: P215/60 R17.

The wheel diameter will be the last number in the series. In this example, the car’s rim diameter is 17 inches. Rim size (also known as rim diameter) is the most important factor to consider when purchasing tires that will fit your vehicle perfectly.

Simply put, the first number is the width of the tire in millimeters, the second number is the aspect ratio of the tire, which is the height of the sidewall as a percentage of the width, and the third number is the diameter of the tire in inches.

First, the sidewall of your tire contains all the information you need to understand everything about that particular tire. This information must be indicated on all tires, regardless of the manufacturer’s brand.
This information can be read in different ways. For example, it could simply be 35×12.5 R17 or it could appear as P265 75 R15. If this is the first listing, here’s the breakdown. The first number indicates your tire size is 35 inches, and the second number indicates the tire width is 12.5 inches. The third indication is the tire type is radial and has a diameter of 17 inches.
The second listing is a metric setting and is most often found on factory size tires. From left to right, the letter P denotes a passenger tire, and the number 265 denotes the width of the tire in millimeters. That 75 is the aspect ratio of the tire, which simply means that the height of the tire is equal to 75 percent of its width. Finally, as with the first set of numbers, R15 means it is a 15-inch radial tire.
Those who have metric readings on their tires can simply plug them into a tire conversion calculator to determine their tire size, or look up the appropriate value in one of the conversion tables below.

From overland vehicles to beautiful custom builds, we’re making our way through the West Hall during this year’s SEMA event.
Stay tuned for product and build information, as well as plenty of interviews with automotive and off-road experts throughout the week. Failure to replace your tires could be detrimental to the health of your vehicle and your own safety. Tires should be replaced as the treads wear out. When it’s time to change your tires, be sure to read our helpful tips on choosing the right tire for your car.
According to the NRCS, “In the United States, tire tread depth is measured at 32 inches. New tires typically have a tread depth of 10/32 inches or 11/32 inches…The U.S. Department of Transportation recommends replacing tires when they reach 2/32 inches.” The easiest way to check if your protectors are in good condition is to use a coin. Insert the penny into the tread groove with President Lincoln’s head facing down. If you can see Lincoln’s entire head, it’s time for new tires.
Now that you know you need new tires, you also need to know about the different types of tires available in the market. There are many different types of tires to choose from, but your choice will depend on what type of car you have. The tires you choose should also suit your driving style and the conditions in which you will be driving your vehicle.

If you drive a front-wheel drive vehicle, you don’t have to replace all four tires. On these types of vehicles, the front tires usually wear out faster than the rear tires, so replacing two is fine. Just make sure the new tires match the ones you already have. Place the new tires on the back of the car and the old tires on the front. With all-wheel drive or four-wheel drive, it is recommended to replace all four tires.
Tires have different characteristics that you need to know before purchasing. Have you ever noticed that there are a lot of numbers and letters written on the sidewall of a tire? They will give you all the information you need to select new tires for your vehicle.
When you look at what is written on the sidewall of the tire, you will see several different letters. “P” stands for passenger car tires—they are designed for cars, SUVs, minivans, crossovers, and small pickup trucks. “LT” stands for lightweight truck tires for towing trailers or heavy-duty vehicles. “ST” means special tires that are also designed for trailers. “T” means the tire is a temporary spare, and “C” means it’s a commercial tire. If a tire does not have a letter at the beginning, it means it is a European tire – typically the tire is classified as a “P” or “LT” tire.
The number that follows the letters indicating the tire type will tell you the width of the tires. Tire width is the measurement of the widest point from sidewall to sidewall. A three-digit number is measured in millimeters; Tire widths typically range from 150mm to 335mm.

The next set of numbers you’ll notice represents the aspect ratio, which is the profile of the tire. This is the tire size in inches from the sidewall to the wheel rim. This number consists of two digits and can range from 40 to 70. Simply put, the larger the sidewall, the larger the aspect ratio will be.
The next number along the sidewall indicates the tire’s internal construction. The “R” stands for radial tires, which are the most common vehicle tires today. They are designed for better grip, comfort, durability and economy. The letter “D” stands for bias-ply tires, which can be found on both motorcycles and trailers. D-type tires use a bias-ply design consisting of criss-crossed piles.
The next two numbers indicate the diameter of the rim. This is the distance from one end of the rim to the other, measured in inches. The tire wheel diameter can range from 8 to 28 inches. The larger the rim diameter, the larger the car.
The load index may consist of two or three digits. The load index shows how much weight a tire can support. For example, a load index of 65 can support 639 pounds, while a load index of 150 can support 7,385 pounds.

The last letter on the list is the speed rating. This letter will tell you how long the tire can run at maximum speed. There are many different ratings: the L tire has a top speed of 75 mph, while the Y tire, typically used on sports cars, can reach speeds of over 185 mph.
You also need to consider the price of the tire; replacing all four can cost a total of $500 to $700. Keep in mind your budget and the current condition of your vehicle to ensure that tire replacements are worth the money.
Another tip for choosing the right tire for your car is to keep in mind where you live. If you live in an area prone to bad winter weather, consider winter tires. They will provide you with better traction on snow and better withstand low temperatures. If you live in a warm-weather state like Florida, summer tires may be right for you. Summer
