Size 245/70 R16
The tyre size is located on the sidewall and consists of 4 parts.
Exemplary size 245/70 R16 describes the most important parameters that are necessary for drivers when choosing tyres for a car.
Width – it is a key value which is at the beginning of the sequence of characters and is expressed in millimetres. It changes every 10 millimetres, so we have such models as: 205/ 215/ 225/.
The tyre width is the distance from the extreme point of the outer sidewall and the furthest point of the inner sidewall. Aspect ratio - this is the second value describing the tyre parameters, i.e. the percentage ratio of model sidewall height to its width.
Using the example, with a tyre size of 245/70 R16, a profile of 70 should be noted, so the profile height is nothing more than 70% of the model width of 245mm. Tyre type – available in two variants:: R - radial and D - diagonal.
Rim diameter - this is a value expressed in inches.
