Previously, we've detailed how to fix a flat tire. Of course, a large part of the reason for a flat tire is the tire pressure problem. Let's take a closer look at the scope of tire pressure policies.
The correct tire pressure is determined by a number of factors, including tire size, sidewall thickness, rider weight, and riding conditions. Generally, fully inflated tires are best for smooth surfaces; slightly underinflated tires may be better on rough roads or trails.
In the US, pounds per square inch (psi) is standard; bars are the metric equivalent. Here is a guide to tire pressure:
- Road bike: 80-130 psi / 5.5-9 bars
- Comfort bike: 35-70psi / 2.2-4.8 bars
- Mountain bike: 30-60psi / 2.1-4.2 bars
Pinch flats can occur when an under-inflated tire compresses all the way to the rim, causing 2 small holes that look like snake bites. However, over-inflation does not cause flats, although it is possible to blow out the tube in extreme circumstances.
Check your tire pressure with a tire pump or gauge. You'll need to carry your own tire pressure gauge if you have a lower-end tire pump without a psi gauge. Identify whether your valve stem is a Presta or Schrader (the slimmer Presta valve requires the top nut to be undone before checking pressure).
Of course, while maintaining the proper tire pressure, you should also pay attention to maintaining the safety of the tire during use to avoid flat tires. You can refer to the 4 Things You Can Do to Avoid Flats we wrote earlier, so as to ensure safe riding conditions , it can also prolong the use time of tires and bring you a better riding experience!
