Commuter bike tires: Wider and stronger

Check for wear: The tread of a tire usually has a wear indicator. These are usually small pits in the rubber. When these potholes disappear, it's time to change the tire. If your tire does not have a wear indicator, let the air out of the tire and see how thin and flexible the center of the tread is to determine the wear. If the body is sticking out of the tread, the tire has been sitting for too long, while for mountain bike tires, the bump rounding out or the grip dropping is a clear sign of wear. In all cases, rear tires usually wear out faster than front tires. Check the tread for damage: Check the tread for cuts. You may also find small pieces of glass or other debris embedded in the grooves of tread or mountain bike tires. Use tools to pry them out before they go deep into the tire and cause a blowout. Check for tire side damage: Cuts may occur on the tire side, but wear damage is more common. Both of these conditions can lead to tire failure, so if the damage could compromise the structural integrity of the tire, the tire must be replaced. If the tires are old or chronically underinflated, cracks may appear on the tire side. Check the bead for damage: If the tire has bottomed on the rim, the bead may be damaged. A more common cause of rim brake wheels is the brake block rubbing against the tire while braking. Make sure the rim brake blocks are properly aligned to avoid this and replace if worn. If the tire is badly damaged, replace it. Keep the sealant adequate: If you are using a vacuum tire, the tire sealant will dry out over time. Check the tire bead regularly to see if there is still liquid sealant in the tire, if not, refill. How often you need to do this depends on the conditions and the sealant you use; You may need to do this once a month or keep it for six months or more.
