Tire pressure optimizer
The right tire pressure is one of the cheapest upgrades to how your bike feels — softer for comfort and grip, firmer for less drag. Tell us a few things and we'll give you a starting pressure to run.
Just your body weight — we'll add a typical bike and gear estimate (~10 kg) for you.
Printed on the side of your tire, in millimetres (e.g. 28, 32, 40).
Set your pressure for the surface you'll actually be on — not the bike you own.
Pressure isn't set-and-forget. The same bike wants different pressure on different days — softer when it's rough, firmer on smooth tarmac. It's worth adjusting when you know where you're headed.
Tubeless tires can safely run a little softer. Not sure? Leave it on "Tubed" — most bikes come that way.
The rear runs higher because it carries more of your weight — that's normal, not a mistake.
Before you inflate: never go above the maximum pressure printed on your tire or rim. If you have hookless rims (common on newer road and gravel wheels), the limit is usually 73 PSI / 5 bar regardless of any calculator — check your wheel specs if you're unsure.
One approach, not a rule — the best pressure is the one that feels right under you. Start here, then trust your hands and your comfort over any number.
