Wrangler AT/R

What does it mean?

The tire section width is the linear distance in millimetres between the outsides of the sidewalls of an inflated tire excluding elevations due to labelling (markings), decorations, or protective bands or rims.

What does it mean?

Section height is half the difference between the overall diameter and the nominal rim diameter. In the course of tire history the shape of the tire has changed from an almost circular tire to flatter, wider tires. This has changed the relationship or aspect ratio (A/R) of the tire section height to the section width from 100% to 70%, 60%, 50%, and even lower.

What does it mean?

The diagram below shows the actual point of measurement which determines the nominal rim diameter.

What does it mean?

Load indices and speed symbols are shown on both tire sidewalls. The first number denotes the tire load carrying capacity in SINGLE application, while the second number refers to DUAL fitment.
M+S (winter/4x4) tires with a lower speed rating than that of the vehicle may be fitted. In some countries it is mandatory that a sticker be placed in the view of the driver indicating the maximum speed of the tire.
This speed may not be exceeded while these tires are fitted.

The SPEED SYMBOL denotes the maximum speed at which a given tire can carry the load indicated by the load index. Only those tires with a minimum speed rating as shown in the vehicle papers may be used on the vehicle. Not valid for V, W, Y, Z.

What does it mean?

The maximum load capacity is indicated by the Load Index. The scale below shows the relationship between the Load Index (LI) and actual load values in kilograms (kg).
