Considerable engineering and research help determine the right tyre size for a particular vehicle model. Hence, automobile experts strictly advise not to alter it to maintain the optimal performance of your vehicle.
Tyre size is an alphanumeric code that you can find embedded in your car tyres’ sidewalls. Let us take an example and understand what this complex code means:
Sample tyre size: 205/55/R16 91H
In this tyre size:
- 205 denotes the tyre’s width in millimetres
- 55 represents the aspect ratio of a car tyre measured in percentage of the total tyre width R denotes the radial construction of a model. Other types of tyre constructions are bias-belt and diagonal cross-ply.
- 16 is the rim diameter of the tyre estimated in inches.
- 91 is the tyre’s load index. Load index refers to the maximum load-carrying capacity of the particular tyre. This code suggests that the tyre can carry a maximal load of 1356 lbs in a fully inflated condition.
- H refers to the speed index of a unit. Speed index refers to the highest speed a tyre can support when fully inflated. Here, the tyre can sustain a maximum speed of 130 mph.
