Planning on getting a set of new rims or second hand rims? Wondering about what tyre specs would fit? Read on.
Before we begin, you need to be familiar with the tyre specifications. The specifications of a tyre can be found on its sidewall and typically look like this:
What it means?
A is the Section Width. In the example above, it means the tyre has a width of 195mm.
B is the Aspect Ration. It is the height of the sidewall expressed as a percentage of the width. In the example, the sidewall is 65% of the width (195), which makes it 195 x 0.65 = 126.75 mm
C is the Tyre construction. R denotes radial construction, which is typical of passenger tyres.
D is the Rim diameter in Inches. So 15 means that the tyre can fit rims of 15 inches.
E is the Tyre Load Index. It represents the maximum weight the tyre can carry. By looking up a Load Index table, 91 (in the example) gives you a load capacity of 615kg.
F is the Speed Index. It is also known as the speed rating as it tells you the maximum speed the tyre is suitable for a full load. By looking up the Speed Index table, you will see that T allows you a maximum speed of 190km/h.
