How to find
your tyre size.
A quick look at the side of your tyre helps us confirm the right replacement. Here’s what to look for and why we ask for more than your registration.
1. Look on the tyre’s sidewall.
The size is moulded into the rubber on the side of the tyre, between the tread and the wheel. Look for a sequence like the example below. Check the tyre that needs replacing; the front and rear tyres may be different sizes.
Park safely, switch off the engine and apply the parking brake. Never stand in traffic or crawl underneath the vehicle to read a tyre. If you cannot check safely, call us instead.
2. Copy the size and the rating beside it.
Illustrative example only. Copy the markings on your own tyre.
| Marking | What it means |
|---|---|
| 205 | Tyre width in millimetres. |
| 55 | Sidewall height as a percentage of the width. |
| R | Radial tyre construction. |
| 16 | Wheel diameter in inches. |
| 91 | Load index: a code for the tyre’s load capacity, not a weight in kilograms. |
| V | Speed rating: the letter next to the load index. |
For this example, enter 205/55 R16 in the tyre-size box and 91 in the load-rating box. You can include the speed letter too, for example 91V.
Some van tyres show two load numbers, such as 104/102. Copy both numbers. Tell us about any XL, Extra Load, C, CP or run-flat markings too, or send a clear photo so we can read them.
Why do we need the size as well as the registration?
Your registration helps identify the vehicle and its possible tyre specifications. It does not always confirm the exact wheels and tyres currently fitted.
- The same model can have several factory wheel sizes or wheel options.
- Wheels may have been changed by a previous owner.
- Some vehicles use different tyre sizes on the front and rear.
- Tyres of the same size can have different load and speed ratings.
Checking the sidewall alongside your registration helps us quote accurately and bring a suitable tyre. We also check the replacement specification against the vehicle’s requirements; the tyre currently fitted is not automatically proof that it is correct.
Can’t read it? Send us a photo.
If it is safe to do so, take a clear, close-up photo of the size and the numbers and letters immediately after it. Include the whole sidewall in a second photo if you are unsure which markings matter.
Tell us which wheel needs attention, such as “front passenger side”, and whether you need one tyre or several. If you need front and rear tyres, check both sizes.
The vehicle handbook or tyre-information label, often inside a door opening or fuel flap, can help identify approved specifications. If anything differs or you are unsure, leave the optional fields blank and ask us to check.
Send your registration, make and model, location and what has happened. We’ll help confirm the tyre details before arranging the job.
