How to Read the Numbers


The Breakdown of 205/55 R16 91V:
Width (205): The width of the tyre in millimetres.
Profile (55): The height of the sidewall as a percentage of the width.
Rim (R16): The diameter of your wheel in inches.
Load (91): How much weight the tyre can safely carry.
Speed (V): The maximum speed the tyre is designed for.
Why Accuracy is Critical
Warning: Fitting the wrong size tyre can lead to MOT failure, invalidated insurance, and—most importantly—dangerous vehicle handling.
Why Yellow Tyres Needs Your Exact Size:
First-Time Fix: We carry a massive stock of 70,000+ tyres. Knowing your size means we bring the right one the first time.
Safety: Different car models (even the same year) can have different wheel options. A physical check is the only 100% accurate method.
No Delays: Avoid the frustration of a technician arriving with a 16" tyre when your vehicle actually has 17" rims.
Pro-Tips: How to be 100% Certain
The "Opposite Side" Rule: Don't just check any tyre on the car. If your Front-Left tyre is flat, check the Front-Right tyre for the size.
Why? Many cars have "Staggered Fitment," meaning the rear tyres are wider or a different profile than the front ones.
The Risk: If you give us the rear tyre size for a front tyre replacement, our technician might arrive with a tyre that is too wide to fit, causing a major delay in your rescue.
Still Unsure? Let the Experts Handle It
