Why do my road bike tires keep going flat?

How often do road bike tires go flat?

Racing bicycle tires, which are designed for speed and high-performance, may need replacing after 1,000 miles, but tough bicycle touring tires can last as long as 4,000 miles. The most common sign that your bicycle tires should be replaced is a sudden streak of flat tires. Bicycle tires wear with age, too.

Why do bike tires go flat so fast?

The reason is simple. Like an excited biker, tires heat up when in use causing the air inside to expand. Keeping bikes for a long time without use means the air inside will contract, lowering the pressure, hence they flatten.

Why won’t my bike tires hold air?

If you mistakenly unseat the tire bead(s) on tubeless tires you may have trouble getting it to hold air again if there isn’t sufficient wet sealant inside remaining to help seal the tire. If you run into this situation, you need to add sealant if possible.

Why is my tire flat with no hole?

Flat tires aren’t always caused by a hole in the rubber. Instead, a malfunction or leak in the valve stem can be the culprit. The valve stem is the part of the tire that you unscrew when adding air. Any damage or even dirt on this small piece could cause your tire to lose air until it’s completely flat.

Why do my bike tires keep popping?

Bike tire popping is when the inner tube of a bike tire becomes deflated. This is due to the inner tube being punctured or cut. Most of the time, this happens when biking through a pothole, rock, or broken glass. The inner tube then starts to slowly leak air, which deflates the tire even more.

Should I inflate bike tires to max psi?

Tire inflation basics

The tires don’t sag down and create a large surface area, because it’s simply not needed. A typical road tire should be inflated to something between 90 and 120 PSI. Mountain bike tires, on the other hand, tend to run at much lower PSI.

Why do I keep getting pinch flats?

Poor valve stem.

Valve stems deteriorate and leak air due to the exposure to lots of chemicals on the road. Usually, drivers get a new set along with the new tires. However, if a tire loses air slowly yet over 1-3 psi a month, they may need replacement earlier.
