How to find your tyre size
Here’s what each section of the code means, using the tyre size and specification 175/65 R14T as an example:
- 195 Tyre width in mm
- 55 Tyre sidewall profile – sidewall height expressed as a percentage of its width
- R Radial (rather than a cross ply)
- 16 Diameter of the wheel rim, in inches
- 87 Load rating which must match or exceed the load capacity of your car
- V Speed rating which must match or exceed the maximum speed of your car.
How to change your tyre size
When considering a fitting a wheel of a different size to your car, it is important to obtain expert advice. Naturally a taller or shorter wheel will bring with it the need to fit a tyre of a different profile (height).
You must maintain a combined diameter of wheel and tyre that is as close as possible to the original so that the gearing of the car’s drivetrain is not adversely impacted. Doing so will also ensure that the ride height will not change significantly and the car’s safety will not be compromised. Before changing wheel and tyre size, Swee Hing would recommend checking the guidelines set out by your car manufacturer and it is worth speaking to your insurer, too.
Many drivers choose to fit a taller or wider tyre for cosmetic reasons. The combination of a taller or wider tyre and a lower profile tyre can increase roadholding performance, although the comfort of the car’s ride will be reduced. Alternatively, a large wheel with a low-profile tyre can be replaced with the combination of a more standard wheel and a taller tyre. The latter is quite a common practice when fitting winter tyres to a performance car, for example.
