Tire Pressure Suite
Ensure maximum safety and tire life. Choose the tool you need below.
Use this when installing a different tire size than factory. It calculates the exact PSI needed to maintain your vehicle’s structural load capacity.
1. Original Specs (Door Jamb Sticker)
e.g. “91” in 205/55R16 91V
2. New Tire Specs (Sidewall)
Air contracts when cold. If you fill tires in a warm garage, they will lose pressure outside. Use this to calculate the exact pressure to fill them to *right now* to prevent winter TPMS warnings.
Temperature of your garage/current location.
The coldest average temperature outside.
Awaiting Specs
Enter your parameters above to calculate the safest exact tire pressure.
Recommended New Pressure
Maintains Original Load Capacity
OEM Capacity
0 lbs
New Capacity
0 lbs
Undersized Tire Warning
These tires have a lower max capacity than factory. Running at max pressure is required, but it technically reduces vehicle GVWR.
Current Fill Target
Fill to this pressure right now.
How it works:
You are filling tires in a °F location. When you drive outside into °F weather, the air will contract. Filling to the number above ensures your tires will drop perfectly to your target of PSI when cold.
Disclaimer: Always check tire sidewall to ensure you never exceed maximum rated pressure.
