How do you tell if a bike has a puncture?

Check over the tube to see where the hole is. The easiest way is to pump some air into the tube, then immediately listen and feel to find where the air is escaping. If you’re at home you can use a bucket of water, submerging sections of tube and looking for telltale bubbles.

How do I know if my bike has a slow puncture?

You can determine if you have a flat tire if the rim is squashing the rubber to the ground then obviously it’s flat. On the other hand, if it’s bulged out it’s losing air and needs to be pumped up. Low tire pressure can cause ‘pinch flats’ but too high of a pressure can make for a bumpy and possibly unsafe ride.

Can a bike tire go flat without a puncture?

Having your tires at a too low pressure may lead to pinch flats or snake bites. Pinch flat tires occur when your tire runs at too low pressure and your wheel hits an object on the ground and the rim slices the inner tube through the tire causing two holes on the inner tube. Too high pressure can cause flat tires too.

Most likely, the rubber seals in the valve have lost some life and no longer seal as well as they should. Next time you inflate the tire, put a of oil in the chuck on the pump; vegetable oil, motor oil, chain lube, doesn’t matter. The oil will rejuvenate the rubber and the valve will seal better.

Why do my bike tires keep popping?

The tire is coming unseated from the rim. This is usually caused by over-inflating the tire for the rim and tire combination. For instance, old style rims without a hook (ridge to hold the wire in the tire or bead in place) are not supposed to be used with high-pressure tires (although I’ve never had problems).
