Calculate Recommended Tire Pressure Instantly



Formula Used

Recommended Tire Pressure = (Axle Weight / Tire Maximum Load) * Tire Maximum Pressure

In this formula:

  • Axle Weight is the total weight supported by the axle in lbs.
  • Tire Maximum Load is the maximum load the tire can handle.
  • Tire Maximum Pressure is the maximum air pressure the tire can handle.
  • To calculate the recommended tire pressure, you divide the axle weight by the tire maximum load, and then multiply that by the tire maximum pressure.

Examples

Front Axle Weight (lbs) Rear Axle Weight (lbs) Tire Maximum Load (lbs) Tire Maximum Pressure (psi) Recommended Front Tire Pressure (psi) Recommended Rear Tire Pressure (psi)
12000 20000 6000 110 220 366.67
12000 34000 6175 110 220 608.16

Frequently Asked Questions (FAQs)


What is the difference between the front axle weight and the rear axle weight?

The front axle weight is the total weight supported by the front axle of the truck, while the rear axle weight is the total weight supported by the rear axle.

Where can I find the maximum load and maximum pressure of my tire?

The maximum load and maximum pressure of your tire are usually printed on the tire's sidewall. Be sure to check both for accurate results.

How often should I check my truck's tire pressure?

It's recommended to check your truck's tire pressure at least once a month and before long trips.

Can I use this calculator for other types of vehicles?

Yes, you can use this calculator for other types of vehicles as long as you know the weight on the front and rear axles, as well as the tire's maximum load and maximum pressure. Just keep in mind that the results may not be as accurate for vehicles with significantly different tire ratings than trucks.
