About this calc
Figure out the right tire pressure for your car, your tire size, and how you drive. Street, sport, or track — we balance grip, wear, and heat buildup.
FAQ
- Should I measure tire pressure cold or hot?
- Always cold — before driving or after sitting for 3+ hours. Driving heats the tire and adds 3–5 PSI, which would throw off your target.
- How much does pressure change with temperature?
- Roughly 1 PSI for every 10°F (5°C) of ambient change. It also rises ~10–12% when tires are hot from driving.
- Is lower pressure better for grip on a track?
- Up to a point. Lower cold pressure gives more contact patch when hot, but go too low and the tire rolls onto the sidewall. Measure hot and target a hot window your tire maker recommends.
- Should the front and rear be the same?
- Usually not. Front-engine cars carry more weight up front, so front PSI is typically a bit higher. This calc splits based on your weight distribution.
