Tire Type
This determines what type of vehicle the tire fits: passenger (P), light truck (LT), temporary spare (T), or special trailer (ST). If there is no letter, that means the tire is euro-metric.
Tire Width
This number, also known as section width, denotes the width or density of the tire in millimeters when measured from the widest point of a tire’s sidewall to the widest point of its inner sidewall.
Aspect Ratio
This denotes the ratio of tire’s sidewall height to the tire’s width. Here, the sidewall height is 55% of the width. Low percentages mean smaller sidewall heights, which could be better for taking corners but rougher over potholes.
Construction
The “R” represents the internal construction of the tire. In this case, the “R” means “Radial”. Most tires on the road will have radial construction. Other letters one might see are D (diagonal) and B (belted).
Wheel Diameter
This number represents the diameter of the wheel that the tire is designed to fit. In this case, the tire will fit an 18-inch rim.
Load Index
Refers to the weight a tire can carry at its maximum rate of inflation. The number corresponds to a load capacity found on a load index chart.
Speed Rating
Designates the maximum safe speed at which the tire is designed to carry a load under certain conditions. The range of speed ratings is from A (lowest) to Y (highest), with the only exception being that H falls between U and V. Surpassing the lawful speed limit is not recommended.
Tire Wear Information
At Parker tire, we see a variety of wear and tear on tires every day. This can be caused by driving on over-inflated or under-inflated tires, having an uneven camber, or other reasons.
