Do You Speak Tyre?

The first time you have a puncture in your car and have to buy a new tyre you very quickly learn the secret language of tyres, as well as the importance of keeping a decent car jack, toolkit, spare wheel and wheel-locking nut where you can find them (take it from me, changing a wheel at rush-hour on the M25 on the way to catch a plane is no fun but it’s a lot easier if you’ve got all the gear).

All the info you need to order a new tyre is on the side of the flat one, encoded in a few characters, something like:

165/65R14 79T

In this example:

  • 165 is the cross-section width of the tyre in mm
  • 65 is the thickness of the tyre as a ratio of its overall size
  • R means radial which just about every tyre is anyway
  • 14 is the diameter of the wheel the tyre fits, in inches (oddly)
  • 79 is the load rating – heavier cars need a higher rating
  • T is the speed rating – some tyres are built for high-performance cars


This is all you need to order a new tyre, you don’t need get the exact same make as the punctured one but it does have to be compatible to be safe. And you don’t need super-duper Goodyear Eagle F1 tyres if all you do is drive your Ford Fiesta to the shops and calmly float up and down the motorway.

If you’re in Aldershot or Farnborough why not ask Aldershot Tyre and Exhaust Centre for advice – they’ve been helping the drivers of the area with tyres since 1968 and can ensure you get the best tyres for your car without spending a fortune.
