How to Read Tyre Sidewall Markings (Size, Load & Speed) — London MOT Quotes

Answers “how to read tyre size” and “what do tyre numbers mean” — essential for accurate mobile fitting quotes in London.

Accurate quotes for mobile tyre fitting London depend on accurate data. The sidewall shows size (e.g. 205/55 R16), load index (91) and speed rating (V). People also ask: Where do I find the right tyre size? — on the sidewall and the manufacturer placard in the door shut. Wrong run-flat or load ratings waste a journey across Westminster or Croydon traffic.

Quick reference

  • 205 — Section width (mm)
  • 55 — Aspect ratio (% of width)
  • R16 — Rim diameter (inches)
  • 91 — Load index
  • V — Speed rating

Why this matters for London call-outs
