Car Tyre Size Explained | Tyre Specifications

What Does Tyre Size Mean?

Understanding the basis of your tyre size is key when it comes to buying the right one for your vehicle. Essentially, it consists of three main parts:

  1. Width of the tyre – seen from the front of the car.
  2. Profile of the tyre – represents its height from the outer edge to the rim.
  3. Diameter of the rim.

Simply, it’s like putting together pieces of a puzzle to get the complete picture of your tyre’s dimensions.

How to Read Tyre Size | What Do the Numbers and Letters on the Tyre Mean?

Reading your tyre size might seem like cracking a secret code, but it’s pretty straightforward once you know what to look for.

Let’s break down the example commonly seen on Australian cars – 205/55 R16 V.

The tyre size consists of five components; three letters and two numbers, and the sidewall code holds the key to understanding them. This code reveals details about the tyre’s size, construction, load-carrying capacity, and speed rating.

Car Tyre Size

Here’s the breakdown:

  • 205 – Tyre Width

This number represents the normal section width of the tyre in millimeters (205mm). It tells you how wide the tyre is.

  • 55 – Tyre Aspect Ratio

It refers to the profile of the tyre – the distance between the outer edge and the wheel of the tyre when seen from the side. It’s expressed as a percentage of the tyre’s width.

In our example, the profile is 55% of 205mm, which equals 112.75mm. This number typically increases in increments of 5.

  • R – Radial / Construction

 It stands for ‘radial’, which is the construction style of the tyre. Radial is the most common type of tyre used today.

  • 16 – Wheel Diameter

This denotes the rim size or the diameter of the inside of the tyre, measured in inches. It increases in increments of 1.

  • V – Speed Rating

This is a symbol representing the speed rating of the tyre. It indicates the maximum speed at which the tyre can safely operate, provided it’s in good condition, properly installed, and inflated to the recommended pressure.

The letters represent different speed ratings for the tyre, ranging from 140 km/h to 300 km/h. In this instance, it’s marked as a V, indicating a maximum speed rating of 240 km/h.

Additionally, in some tyre sizes, there might be a number accompanying the letter. Let’s suppose it’s 205/55 R16 95V, the number 95 with the letter V indicates the maximum load capacity, referring to 690kg load per tyre.

How to Find the Car Tyre Size?

If you’re wondering where to find your tyre size, there are a few places to look.

  • Car Owner’s Manual:

Your vehicle’s manufacturer will provide the recommended tyre size in your owner’s manual. This manual contains all the details you need to make a smart decision about your tyres.

  • Tyre Placard:

Another spot to check is the tyre placard, usually located inside the driver’s door jamb. This placard displays important information such as tyre size and recommended tyre pressures.

  • Tyre Sidewalls:

You can also read a tyre size information moulded into the sidewall of your tyres. This code system helps you understand the technical capabilities of your tyres and ensures you drive safely. Additionally, it assists you in identifying the right replacement tyres when it’s time for a change.

Can I Use a Different Tyre Size on My Car?

It’s crucial to adhere to the tyre sizes recommended by your car’s manufacturer. Always refer to the approved tyre sizes listed in the vehicle owner’s manual. If you’re uncertain, don’t hesitate to consult the professionals at All Aspect Motors.

Opting for a tyre size outside of the manufacturer’s recommendations can have several consequences. It may affect the accuracy of your speedometer and odometer and could potentially compromise the safety and roadworthiness of your vehicle.

I sold my car to All Aspects Motors after the engine light came on and I decided I didn’t want to deal with the repairs. They had already looked over the car previously, so the whole process was quick and easy. They gave me a fair offer, explained everything clearly, and made the sale completely hassle-free. Payment was fast and the customer service was excellent. Highly recommend All Aspects Motors if you’re looking for an honest and easy way to sell your car.

Very good to deal with and was no problem with adding things for me to get done to my vehicle and very up front with drop off and pick up times and always keeping me updated with how things are going and very polite and well mannered which can be a very rare commodity these days especially respect for the customer. I give All Aspects Motors a 9 as can't give a 10 as no one is perfect LOL
