UK online tyre reference; checked 30 September 2026
Selected tyre sizes from Toyota UK’s model guide. It does not assign these rows to individual years or trims, and its discontinued-model section is historical. Load/speed ratings and rim widths are not provided. Match the exact vehicle placard and handbook before buying.
Check your exact vehicle. These are selected documented combinations, not a registration lookup or a complete fitment list. A tyre with the same size can have a different load index, speed rating, construction or manufacturer approval.

|---|---|---|---|
| GR Yaris; main model section | 225/40 R18 | 18 inch diameter; rim width not listed | Front and rear |
Ratings appear only where recorded in this selection. An omitted rating or axle assignment means it has not been established here. Wheel width and offset are shown where supported; diameter alone does not specify a replacement wheel.

These catalogue summaries group tyres by size only. They do not check compatibility with your GR Yaris. Confirm all vehicle requirements before choosing a tyre.

Before buying for your GR Yaris
- Match the vehicle’s year, generation, engine and trim to this edition.
- Check the fitted wheel option and the approved specification for each axle.
- Confirm load and speed ratings, XL and HL, run-flat construction and any manufacturer markings.
- Compare the exact tyre variant and ask your manufacturer or fitter if anything differs.
