When a bike tire goes flat while riding home, it is important to know that riding on a flat tire is generally not advisable because it can damage the tire and rim. The best option is to fix the flat tire before continuing the ride or get a ride home if fixing it on the spot isn't possible. Here is what typically causes a flat tire and what can be done:
- A flat tire is most often caused by a puncture from sharp objects like glass, metal, or thorns on the road.
- Sometimes the valve may leak or the tube could have a slow leak.
- Riding on a flat tire can cause damage to the rim and make it harder and rougher to ride.
To fix a flat tire, the basic steps are:
- Remove the wheel from the bike.
- Use tire levers to pry the tire off the rim.
- Take out the tube, find the puncture by inflating and submerging it in water or feeling for air leaks.
- Patch the tube or replace it with a new one.
- Put the tube and tire back on the rim.
- Inflate the tire to the recommended pressure and reinstall the wheel on the bike.
Carrying a tire repair kit, spare tube, tire levers, and a portable pump is recommended for rides to fix flats on the go.
If a flat tire happens mid-ride and no tools are available, or if the flat is severe, it may be safest to call for a ride home to avoid further damage.
In summary, if the bike tire is flat while riding home, either fix the flat using a repair kit or get a ride home. Riding on a flat tire can damage the bike. Knowing how to fix flats and being prepared can make cycling safer and more enjoyable.
