Higher pressure, especially with 25-28 mm tires and smooth pavement.

Bike Tire Pressure Guide
The correct bike tire pressure is a starting range, not one magic number. Rider weight, tire width, tube or tubeless setup, surface, casing, and rim limits all change the answer.
Simple starting ranges
These ranges are only context. Your actual safe number depends on tire width, rider load, setup, surface, casing, and the lower maximum from the tire or rim maker.
Middle range for comfort, grip, and rim protection on mixed surfaces.
Lower pressure for trail grip, casing support, and impact control.
Very low pressure for snow, sand, and huge tire volume.
Wider tires have more air volume, so they can support the rider at lower pressure. Schwalbe notes that wide tires are generally used at lower inflation pressure.
Tubeless setups can often start lower because there is no inner tube to pinch. With tubes, add support if pinch flats are a concern.
The rear tire usually starts higher because it carries more load. Lower front pressure can improve steering grip and comfort.
A chart cannot know measured tire width, casing, inserts, rim maximum, or route texture. Use charts for context, not final pressure.
Never ignore limits
Do not exceed the lower maximum from the tire or rim maker. Hookless road setups need extra care: SRAM explains that Zipp hookless TSE wheels use a 73 PSI limit. Your exact rim and tire may publish a different limit.
Why small changes work
If the result feels close but not perfect, change by 1 PSI at a time. Big jumps make it harder to understand whether the front tire, rear tire, casing, or surface caused the change.
How to tune after a ride
- Harsh ride: drop 1 PSI and retest.
- Poor grip: drop 1 PSI, usually front first.
- Rim strike: add 1-2 PSI to that wheel.
- Tire squirm: add 1 PSI front or 1-2 PSI rear.
- Burped air: add pressure and check tire/rim fit.
Focused calculators
Use the road bike tire pressure calculator, gravel tire pressure calculator, or MTB tire pressure calculator if you want setup-specific guidance.
Once you have a starting number, use one repeatable gauge and write down front and rear pressure after each useful test ride. The digital tire pressure gauge guide explains why repeatability matters, and the tubeless repair kit guide covers what to carry if you run lower tubeless pressures on gravel or MTB rides.
