I inflate my tires before every training ride. I want to be as comfortable, fast and safe as possible. Too little pressure I slow down, run the risk of unseating a tire on a hard turn or pinching a tube. Too much pressure the ride is uncomfortable and unforgiving. So what is the ideal tire pressure?
There are many considerations – your weight, riding style, road surface, tires, weather … You need to experiment and find the best combination of tires and pressure that works best for you. Here are some basic guidelines for your road bike –
- inflate your tires before every ride
- smaller riders (120 lbs or less) inflate between 90-110 psi
- larger riders (170+ lbs) inflate between 100-130psi
- include the weight of your bike and any load your are carrying
- inflate the front tire 5 psi less than the rear
- if the road is exceptionally smooth, increase the pressure 10 psi
- if the road is wet, reduce pressures 5-10 psi
- if you will be doing hard cornering or long descents drop pressure 5-10 psi
- never inflate your tires over the manufactures maximum recommended tire pressure
