Tire Load Rating Basics
Tire load rating shows the maximum weight a tire can safely carry. This rating helps drivers choose the right tire for their vehicle.
Understanding load ratings is important for safety and tire performance. It prevents tire damage and accidents from overloading.
What Load Rating Means
Load rating tells you the highest weight one tire can hold. It is shown as a number on the tire sidewall.
This number matches a load index chart that converts it into pounds or kilograms. It helps match tires to vehicle needs.
- A higher load rating means the tire can hold more weight.
- Using tires with too low a rating can cause tire failure.
- Always check load rating when replacing tires.
How Load Ratings Are Measured
Load ratings come from tests done by tire makers. They measure the tire’s strength and how much weight it can carry safely.
Tests include inflating the tire and adding weight until it reaches its limit. The rating is set with a safety margin.
- Load rating is linked to tire size and pressure.
- Higher air pressure usually means higher load capacity.
- Ratings follow industry standards for consistency.
