Basic Maintenance Procedures
A tire blowout can lead to a dangerous situation, not to mention being very
inconvenient. It is important to inspect your tires before you ride.
• Inspect both tires for bumps and bulges in the sidewall and tread.
• Look closely for cuts or other damage.
• Inspect both tires for embedded objects like glass, nails or sharp rocks that
you may have picked up.
• Inspect the tread depth of your tires and replace them if the depth drops
below a tenth of an inch, or if you notice a serious reduction in traction.
• Check for the position of the valve stem. A tilted valve stem can mean that
the tube is slipping inside the tire and can cause a blowout.
• Be sure that both tires are inflated to 30-40 PSI. If you use a high-powered
air hose, like those found at a gas station or tire shop, inflate carefully as the small
tires on the TT40 minibike will inflate very quickly and could explode if they are
severely over inflated.
Use an air chuck as shown below to ease inflating the tires.
