Tires are a vital part of your car and if you want to ensure your car's overall performance and safety, then installing the right tire is imperative. Choosing the right tire for your vehicle depends on the conditions you drive and the response and handling you want your car to provide. If you are in the market for some new tires, then the first thing you should know is the right size tire for your vehicle. Now, finding your car's tire size isn't that hard.

All the information you need is in your owner's manual or somewhere on the vehicle itself. If you already know which size tire you need, then a quick search on the internet should do the trick. Just search with the term "find a tire shop near me," and you will be on your way to getting yourself some new tires. However, if you don't know how to find your car's tire size, then we here at AutopartsZ have an easy guide for you to follow.

Our job here at AutopartsZ is to ensure every car owner finds the right tire, auto parts, repair shop, and automotive information about every operating vehicle in the United States. So we created this easy guide for you to help you find the perfect fit for your car. There are three ways you can find the right tire size. The first is the traditional method, the second is to find the tire size by make and model, and the last is to use the car's VIN to find the right tire size. You will find all three methods in the following passages. So let's begin!

The Traditional Method

Well, the traditional method is basically you looking up your car's tire size in the owner's manual or on the vehicle. If you don't have the owner's manual, then simply doing a quick search on your car will help you find all the information you need. So let's check out how you can see tire information on your car:

Where To Find The Tire Size?

Finding the tire information is relatively easy. If you don't have access to the owner's manual at the moment, then you will find the tire fit information on the driver's side door jamb, or inside your glove box door, or within your gas tank hatch. Also, if you have the correct tire size already, you will be able to find the tire information on your current tires' sidewall. Regardless of wherever you find the tire fit data, you will need to decipher a sequence of numbers and letters to know what tires you need.

How To Read Tire Size?

So you've found the long sequence of numbers and letters that is supposed to be your car's tire fit information. However, you have no idea what it means. Well, don't worry, it's quite simple, really. The sequence will start with letters. It will either have the letter "P," which is the "P-metric" for passenger cars, or it will have the letters "LT," which stands for the "LT-metric," meaning you will need light truck tires. Light truck tires are designed to be used by cars to draw heavy loads and pull trailers. Both of these metrics are assigned by the Tire and Rim Association. There are other designations like when you find the letter "T." It stands for "Temporary" it's a metric assigned to spare tires. While "ST" means "Special Trailer."

After the letters, you will see numbers; the numbers represent the width of the tires you will need. The width is measured in millimeters and is up to the "slash or divider" within the sequence you find. After the divider, it represents another metric. Your tire's width is the measurement from one sidewall to another, and knowing this is very important in finding the right tire size. After the width, there is a "slash or divider" followed by numbers representing the aspect ratio of the tire.

Aspect ratios are measured in percentages. The tire manufacturer calculates the aspect ratio by dividing a tire's height off the rim by its width. If your car has an aspect ratio of 75, then the tire's height is 75% of its width. After the aspect ratio, you will see another letter.

The letter represents the type of internal construction for the tire. There are two types of construction one is represented by the letter "R," which stands for "Radial," and the other is represented by the letter "D," which stands for Diagonal or Bias Ply.

Most of the tires within the States are radial tires. These are tires where the tire's internal ply cords are oriented in a radial direction. Meaning it's from one bead over to the other, essentially perpendicular to the axis of rotation. The next thing you will notice in the sequence after construction is the rim diameter code.

There are quite a few rim diameter sizes that are popular, and they are all measured in inches. After the rim diameter code, you will notice there's space then another number. That number is the load index. This number tells us how much load the tires are supposed to be able to withstand. Now, these numbers range anywhere from 1 to 150. Each number represents the load index carrying capacities of the tires that can go anywhere from 99 to 7385 lbs.

The last part of the sequence is a single letter, and it represents the tire's speed rating. The speed rating letter corresponds to a particular speed capability determined through standardized laboratory tests. For example, any tire with a speed rating "S" is rated for up to 112 mph, while tires rated "R" can only support up to 106 mph.

Now, that's not the cruising speed for the tires, so make sure you follow legal speed limits on roadways. One thing of note is that tires with a higher speed rating offer increasing handling performance, and replacement tires you buy should have the same or higher speed rating if you want to maintain vehicle speed capability.

However, if your car has different speed ratings for other tires, then the tire with the lowest speed rating will dictate your car's top speed. So that takes care of the traditional method. If you think this is too confusing or takes up too much of your time, then we are with you on that. We here at AutopartsZ always believe in making the lives of car owners easier. The following are the easy methods we recommend you use.
