Tires are more than “where the rubber meets the road,” and understanding sizes, load ratings, why ply no longer matters, and more is important for today’s fleet managers.
Tires are more than “where the rubber meets the road,” and understanding sizes, load ratings, why ply no longer matters, and more is important for today’s fleet managers.
Tire-sizing systems used on OE light-truck tires include Euro-Metric, P-Metric, and LT-Metric. Many 1/4- and 1/2-ton vehicles use Euro-Metric and P-Metric tires, while 3/4- and 1-ton vehicles use LT-Metric sizes.
Tire load ratings must be followed when selecting a tire and wheel package. The tire must safely support a given amount of vehicle weight. If the load rating is insufficient, the tire may become overheated and can self destruct.
