What’s one of the worst things that can happen to you while you are riding your bike. If your answer is bursting your tire, then we both share the same dissimilarity.

There is nothing worse than hearing the sound of your tire bursting while you are enjoying riding your bike.

This situation is inevitable, but we can take a few guidelines and precautions in practice to avoid it as much as possible.

Many people are ignorant about their bicycle tire pressure, which eventually leads to the tire getting damaged way before its prime.

To have a comfortable and safe bike riding experience, you need to know the correct pressure required for your bicycle tires.

Whether you have a road bike, hybrid bike, or mountain bike will determine your bike tire pressure.

If you are an avid bike rider, you must be well versed with the PSI bar system of tire pressure.

PSI is the unit of pressure and is used as a measurement parameter on the pressure measuring gauges to fill your tire with air.

Be aware of your tires’ tube type. Are they Inner tube tires or Tubeless tires? An Inner tube tire variety requires to have high pressure to avoid the tire suffering from pinch flat.

Pinch Flat occurs when a large impact on the tire causes the tire’s bead to pinch the inner tube and puncture it. There are a plethora of reasons for a bike tire to go flat.

This Puncture would not happen in a tubeless tire, so the pressure is generally lower than an inner tube tire.

Other factors responsible for your bike’s tire pressure can be your body weight and the terrain you travel.

Why is Tire Pressure so Important?

Proper tire pressure gives you the advantage of improved grip level and rolling resistance.

Grip Level

The flexibility and adaptability of a tire make it have more friction and grip while in use. An overinflated tire won’t adhere to the surface, thus making the bike lack a strong grip.

Rolling Resistance

Rolling Resistance is how much rubbing happens among the tire and surface. Resistance helps you have greater control over your bike. Have good rolling resistance in your bike by having the perfect air pressure in your tire. Not less, Not more.

The tire pressure guide:

The best tire pressure for your bike will depend on

  • The kind of bike you have,
  • Type of tires you have fitted,
  • Rider weight,
  • Road conditions,
  • Weather conditions. 

Mountain Bike Tire Pressure

Mountain bike requires lesser pressure than the other variety of bikes as the dynamic nature of there terrain. Lesser pressure makes it easier for the bike’s tire to adapt to the rocky paths they travel.

The mountain bike tire’s voluminous nature makes it less likely to pinch flat despite these lower pressures.

Suggested tire pressure – for a ≤70Kg rider:

  • Inner tube tyre: 36PSI (2.5Bar) Front

                                    38PSI (2.6Bar) Rear

  • Tubeless tyre: 26PSI (1.8Bar) Front

                                  28PSI (1.9Bar) Rear

Adjustment suggested for weight:

  • Add 1 PSI for every 5Kg over 70Kg 

Road Bike Tire Pressure

On the contrary to mountain bikes, road bikes require higher pressure as they usually encounter well-leveled roads. A high-pressure tire helps in achieving rolling resistance and control over their bikes.

Suggested tire pressure – for a ≤70Kg rider:

  • Inner tube tire: 90PSI (6.2Bar) Front

                                    93PSI (6.4Bar) Rear

  • Tubeless tire: 80PSI (5.5Bar) Front

                                  83PSI (5.7Bar) Rear

Adjustment suggested for weight:

  •  Add 2PSI for every 5Kg over 70Kg
  • Subtract 2PSI for every 5Kg under 70Kg

Hybrid/City Bike Tire Pressure

Hybrid/City bike tires generally run at a higher pressure than mountain bike tires but a lower pressure than narrower road bike tires.

It renders the most beneficial settlement between grip and rolling resistance required for the bike to function efficiently.

Suggested tire pressure for – for a ≤70Kg rider:

  • Inner tube tire: 50PSI (3.4Bar) Front

                                    55PSI (3.8Bar) Rear

  • Tubeless tyre: 38PSI (2.6Bar) Front

                                 40PSI (2.75Bar) Rear

Adjustment suggested for weight:

  • Add 1PSI for every 5Kg over 70Kg

I had also come across guidelines of tire pressure according to the weight of the rider. I have added that as well in this article to give you greater clarity over this variation.

Tire Pressure in PSI Bar
Rider weight in lbs (kg)FrontRear
Less than 125 (57 kg)108 (7.45)112 (7.72)
125-150 (57-68 kg)114 (7.86)118 (8.13)
150-175 (68-79.5 kg)121 (8.34)126 (8.68)
175-200 (79.5-91 kg)130 (8.96)135 (9.31)
Greater than 200 (91 kg)140 (9.72)145 (10.0)

Tire Pressure suggested During the Rainy Season

I have heard and read many amateur bikers suggesting to lower the bike tire pressure during wet conditions.

Is this required? The answer is NO.

Practically, it does not seem advisable to stop your bike and change your bike tire pressure in the mid of a race or a ride.

Assuming that you already have the perfect bike tire pressure, You might face no problem in any given situation.

If you wish to lower it anyway, don’t reduce the PSI by more than two bars. You are reducing your bike pressure lesser than that might lead your bike to squirm and experience a hard time gaining control of your vehicle.

Check Tire Pressure Regularly

A lot of people, including me, generally check their bike pressure by pinching our tires.

We can’t deny that it’s a quick and effective process, but we cannot vouch for the accuracy of this method.

It’s recommended to check your bike tire pressure at least once a week to guarantee optimal performance.

Checking your tire pressure regularly also helps you trach the degradation of your tire. It will help you avoid unexpected tire bursting as you will know exactly when to change your bike’s tires.

I would request you to take the tire pressure discipline sincerely. I can understand that we tend to oversee this aspect of bike safety.

But optimal bike pressure has proved to help bikers regain their control over hazardous situations.

From a safety point of view, make sure you have the required level of air pressure on your bike. Spread this important information to build a community of bikers grounded in safety and precaution.
