19 INCH TYRES

The 19 inch tyre comes in a range suited for use on city cars, luxury cars, touring cars, large multi-purpose vehicles (MPVs), SUVs and high-performance sports vehicles. Although often designed to cover all terrains the 19 inch tyre generally tries to strike the proper balance between off-road ability and on-road comfort. The tyre usually comes with an elongated tread-life and cornering stability for all weather conditions.

The description of 19 inch refers to the final number on the alphanumeric digits that specify the dimensions of a tyre. These last two digits sometimes with a decimal number at the end are explicit to the diameter of the tyre. The first measurement, (three digits), is measured in millimetres and relates to the width of the ground-facing wall of the tyre. The second measurement, (two digits), and sometimes a letter as well, relates to the ratio, (%), of the side-wall to the width of the ground-facing wall. The letter is an additional specification relating to tyre construction or speed rating.

Locate Your Tyre Size Quickly

Your tyre size is listed on the sidewall of your tyres or in your vehicle's manual. It is presented as an alphanumeric list, with each number or letter representing a specific dimension of the tyre.

Here's what some of these numbers and letters mean:

(225) TYRE WIDTH:This number measures the tyre's width from one sidewall to another in millimeters. For instance, a 225/45 R17 tyre is 225 mm wide.

(45) ASPECT RATIO:This is the number following the slash. It represents the height of the tyre's sidewall as a percentage of its width. So in a 225/45 R17 tyre, the sidewall height is 45% of 225 mm.

(R17) RIM DIAMETER:This is the diameter of the rim in inches. A 225/45 R17 tyre fits on a 17-inch rim.
