Safety note

Use your owner’s manual or tire sticker as the source of truth and set pressures when tires are cold. Never exceed the tire sidewall maximum.

Motorcycle tire pressure is a safety critical setup variable that changes steering feel, braking confidence, stability at speed, and tire wear. Low pressure can make the bike feel vague and generate heat, and high pressure can reduce grip and feedback, especially on rough pavement.

The most reliable baseline is the owner’s manual or the pressure sticker on the bike. This calculator helps you start from that baseline or a reasonable preset, then estimate how load mode, system weight, and tire sizes shift front and rear targets.

Use the results as a cold pressure starting point, then fine tune in small steps while staying within your tire limits.

Technical Details

The calculation begins with a baseline pressure for each wheel, either a bike type preset or manual values you enter. When you provide optional manual loaded pressures, those are used automatically for non solo load modes. Otherwise, load mode applies a modest stability bias, most noticeably at the rear.

Total system weight is split between front and rear using the configured load share, then adjusted by bounded factors for surface, riding priority, tire setup, weather, and tire condition. The final recommendation is clamped into a safe window and can be clamped further by optional sidewall maximum pressures.

Safety. Set pressures when tires are cold. Do not exceed the sidewall maximum pressure, and follow your manufacturer guidance for track use, sustained high speed riding, and heavy loads.

FAQ

What should I enter for baseline?

If you have a manual or sticker value, use it. Presets are only meant as a rough fallback when you do not have the bike specific number.

Should I adjust pressure when carrying a passenger or luggage?

Many bikes recommend a higher rear pressure for two up riding and luggage. Use the load mode selector and your manual loaded values when available, then confirm the feel and stability on your first miles.
