It breaks down into key measurements: 265 is the tyre width in millimetres, 60 is the sidewall height as a percentage of the width, R means radial construction, and 20 is the wheel diameter in inches. When buying, also match the load index and speed rating shown on your current sidewall or in the vehicle handbook.

Look at the tyre size printed on the sidewall of your current tyres and compare it with the placard inside the driver door or the handbook. If the approved sizes list includes 265/60 R20, you can fit it as a like-for-like replacement. If not, confirm compatibility before ordering, as changes can affect speedometer accuracy and clearance on full lock.

It is a noticeable change in overall diameter, so it can alter speedometer readings and may affect ride height and gearing. Some vehicles allow both sizes, but many do not. Check the manufacturer-approved tyre sizes first, and only switch if your vehicle documentation explicitly supports both.

For mostly motorway and A-road driving, a road or highway-terrain pattern typically gives lower noise and better wet braking. If you regularly use muddy tracks, grass fields or building sites, an all-terrain option can offer tougher construction and more open tread blocks for traction. Match the choice to your real driving mix so you do not pay for off-road capability you will not use.

Use the load index on your existing tyres as the minimum, and never fit a lower rating than specified by the vehicle manufacturer. Heavier vehicles, towing, and carrying payloads often require higher load indices and sometimes an XL (extra load) marking. When in doubt, select the same load and speed rating as your current tyres and upgrade only if your handbook allows it.
