Inspect the tread to measure wear on city bike’s tires and to know when they need replacing.
Usual signs of wear include:
- tread starting to fray
- appearance of micro cracks
- low tread depth
- carcass is visible.
All of these indicate the tire is worn and needs replacing.
How to remove a tire
To remove the tire, start by deflating the inner tube completely.
Once deflated, use a tire lever to remove it from the rim.
How to fit a tire
To put it back on, place one side of the tire into the bottom of the rim. Next, inflate the inner tube about 30% before putting it into the tire (inflating the inner tube beforehand reduces the risk of pinching the inner tube). Then, insert the other side of the tire into the rim, starting on the side opposite the valve.
Before fully inflating the inner tube, check to make sure it isn't pinched between the tire and the rim.
How to inflate your tire correctly
Inflate your tire carefully. The recommended pressure is shown on the side of the tire. Also, before each outing, make sure that your tires are at the correct pressure for your ride.
When inflating your tire, make sure you inflate it to the suitable pressure for the terrain and the weather conditions you will be riding in.
When riding in wet weather, lower the tire pressure to increase its traction. When riding in dry weather, increase the pressure for better performance.
