How to Identify Your Tyre Size
Yellow Tyres delivers 24/7 mobile tyre solutions in London and Essex—swift, safe, and affordable service.
Step 1: Check the Tyre Sidewall
1. Look at the sidewall of your tyre. You’ll find a code like 205/55 R16 91V. This is your tyre size—don’t rely on online searches alone, as they can be inaccurate.
Step 2: Understand the Code
2. Decode the numbers: 205 (width in mm), 55 (aspect ratio %), R16 (rim diameter in inches), 91 (load index), V (speed rating). Note these for accuracy when ordering.
Step 3: Verify by the Sidewall
The most accurate tyre size is on the sidewall. Other places like the driver’s door or manual may list generic sizes, leading to errors. Stand by your vehicle and call 020 3633 9533—we’ll guide you
Step 4: Contact Us for Confirmation
4. Once you’ve noted the sidewall code, call 020 3633 9533 to confirm. Our fitters can verify your size on-site across London and Essex, ensuring a perfect fit.
