However, if you want to know exactly how much air your tyres are filled with, you’ll need to use a tyre gauge. But where can you find one? In this article, we’ll show you how to find the size of your car tyres using two different methods – by looking at the sidewall and by measuring the circumference of the tyre. We’ll also explain why one method is better than the other, and give you some helpful tips on how to measure your tyres correctly. So read on to learn how to find out the size of your car tyres!

What You Will Need

Before starting your tyre search, you will need to gather the following information:
-The make, model and year of your vehicle
-Your car’s wheel size
-Your car’s configuration (4×4, all wheel drive, etc…)

Once you have this information, it is easy to find out the size of your tyres. Here’s how:
-Use a tire calculator to determine your car’s wheel size. Most calculators can be found online or in a local library.
-Match your car’s wheel size to the corresponding tire size found on online tyre retailers.
-Click on the tyre sizes to view images and read product reviews.
-Choose the tyre size that best matches your needs and budget.

How to Do the Test

There are many ways to test the size of your car tyres. Each method has its own benefits and drawbacks. Here are two methods to help you determine the size of your tyres.

The Boot Method

To use the boot method, you’ll need a spare tyre, a wheelbarrow, and a shovel. Place the spare tyre on the wheelbarrow and fill it three-quarters full with water. Place the wheelbarrow in front of the car so that the tyres are partially submerged. Push the shovel under the front edge of one of the car’s tyres, then place your other foot on top of the tyre and push down firmly. The pressure from your foot will cause the tyre to expand and show if it’s a safe size for your car. Repeat for each tyre.

What to Do If Your Tyre Size is Unknown

If you’ve not been able to find the size of your car tyres, there are a few things that you can do. The most common way to measure the size of a car tyre is to use a wheel spanner. However, if you don’t have one, or if it’s not practical for you to take your car to a garage to have them measured, there are other ways to find out the size of your tyres.

One option is to look online. There are many websites that allow you to enter the make and model of your car, and then it will provide you with the dimensions of the tyres. Another option is to go to a local car dealership and ask them to measure the tyres for you. They may also be able to provide you with a list of tyre retailers in your area who can help you get the right size tyre for your car.


If you’re like most drivers, you probably couldn’t give a rat’s ass about your car tyres. But if your tyre pressure is low or if there are signs that they need to be replaced, it’s important to know the size of your tyres so you can get them changed in a safe and timely manner. To find out the size of your tyres, use our simple guide below.
