How Much Air Should You Put in Your Bike Tires?

One of the most common questions we hear at the Wygodny Rower service center is: “How much should I inflate my tires?”
It’s a great question! Proper tire pressure isn’t just about comfort — it’s mainly about your safety, better grip, and reducing the risk of costly damage.

There is no single “magic number” that works for everyone. The right pressure depends on your bike type, your body weight, and the terrain you ride on.

Quick guide: recommended tire pressure by bike type

Before diving into the details, take a look at this handy reference table. Treat these values as a starting point, not an absolute rule.

Bike type	Recommended pressure (bar)	Recommended pressure (PSI)
Road bike	6.0 – 8.0	90 – 120
City / Trekking	3.0 – 5.0	45 – 70
Gravel	2.5 – 4.0	35 – 60
Mountain bike (MTB)	1.8 – 2.8	25 – 40

Bike type – where do you ride?

Road bike
High pressure is king here. A hard tire minimizes rolling resistance on asphalt, allowing higher speeds with less effort.

Mountain bike (MTB)
Here, the rule is the opposite — lower pressure is your friend. It lets the tire “bite” into the terrain, absorb roots and rocks, and maintain control on loose or muddy surfaces.

City and trekking bikes
This is the sweet spot. Pressure should be high enough for smooth rolling on bike paths, but low enough so you don’t feel every curb or crack in the pavement.

Gravel bikes
A true all-rounder, so adjust pressure to the route. More asphalt? Pump it up a bit. Heading off-road or into the forest? Let some air out.

Your weight (and luggage) matters

It’s simple physics: the more weight on the tire, the higher the pressure needed to maintain its shape.
Lighter riders can safely use the lower end of the recommended range for extra comfort.
Heavier riders — or those carrying panniers or bags — should aim for the upper end.

Watch out for “snake bites”!
Too little pressure combined with higher weight can cause the tire to bottom out on the rim. The result? Two small holes in the inner tube — a classic “snake bite” puncture.

Always read the tire sidewall

Before inflating your tires, check the sidewall markings. Manufacturers always print the minimum and maximum pressure there.

Never exceed the maximum — you risk the tire blowing off the rim or tearing.
Never go below the minimum — the tire can deform, wear faster on the sides, and lose stability in corners.

Weather and surface – a small mechanic’s trick

On wet or slippery surfaces, it’s worth slightly lowering the pressure (by about 0.2–0.4 bar).
This increases the contact patch between the tire and the ground and can save you from slipping on wet leaves, paint markings, or metal surfaces.

How often should you check tire pressure?

Bike tires naturally lose air over time — this is normal and doesn’t always mean a puncture.
How often you should check depends on how frequently you ride.

Ride daily? Check pressure at least once a week.
Ride occasionally? Always check before every ride.

Important: Checking pressure “by hand” is very misleading. A tire at 2–3 bar may feel firm but still be underinflated, increasing the risk of rim damage. Only a pump with a pressure gauge gives an accurate reading.
