Ever wondered what the optimal tyre pressure is?
Many things get taken into account here; rider weight, tyre size, type of bike and where you’re riding. Things have changed in modern times with the addition of the tubeless ready tyre added into the mix. Tubeless tyres are generally for running less pressure without the loss of rolling resistance and added bonus of puncture protection.
Road tyres with tubes (clinchers)
are generally gassed to the max 90-125 PSI (pound per square inch) for improved rolling ability and handling. This can of course change with wet weather and rule of thumb would be 15-20 PSI less than normal.
Road Tubeless tyres
are meant to be softer. Pumped up to the max and any punctures will struggle to seal, the tyre could also blow off the rim, same goes for when not enough pressure has been added. Recommended pressure for road Tubeless tyres would be 80-90 PSI.
Tubular tyres
generally can take a lot of pressure and need it, so the tyre stays seated on the rim, 90-120 PSI would be advised.
The specific pressure will depend on the course you’re taking, smooth tarmac and you’ll want to be at the at the higher end, paved or cobbled streets and some cushion will be helpful.
Always check on the sidewall of the tyre for manufacturers recommended pressure and have a play about.
Pro riders will have fully gassed tyres for a big climb, then tap the valves to release a small amount before hitting the descent (training days of course) Silca has a great calculator online which can come in very handy to get the correct pressure you require.
