Tire Pressure

The single most important job of the tire is to bear the weight of your vehicle and having the right tire pressure is how it does that.

GAWR is Gross Axle Weight Rating – the maximum weight either axle can carry individually – and there will probably be a different rating for both the front and rear axles.
A tire's maximum load is the most weight the tire is designed to carry.
A tire's maximum inflation pressure is the highest "cold" inflation pressure that the tire is designed to contain.
