Notes

  • Values are indicative and may vary by tire design, construction, and manufacturer. Always check the tire sidewall and OEM documentation.
  • Loads are typically specified for cold inflation pressures. Adjust for temperature and altitude as necessary.
  • Never exceed the wheel or vehicle axle rating even if tire capacity suggests otherwise.

About Tire Load & Pressure

Inflation pressure directly affects a tire’s stiffness, footprint, heat generation, and ultimately its load rating. Under-inflation increases deformation and heat, shortening tire life; over-inflation reduces the contact patch and traction.

How to Use This Chart

  1. Identify the required axle load and divide by the number of tires carrying that load.
  2. Find a suitable pressure where the per-tire capacity meets or exceeds the requirement.
  3. Verify limits in OEM and tire maker documentation before implementation.

FAQ

Is higher pressure always better?

No. While higher pressure increases load capacity, it can reduce ride comfort and traction. Stay within the manufacturer’s recommended range.

Do I need to adjust for temperature?

Yes. Tire pressures rise with temperature; always measure and set pressures when tires are cold unless otherwise specified.
