Tyre Maintenance

A tire is a ring-shaped structure that surrounds a wheel’s rim to transfer a bicycle’s load, from the axle through the wheel to the ground and to provide traction on the surface over which the wheel travels. Most tires for automobiles and bicycles are inflated structures which also provide a flexible cushion that absorbs shock as the tire rolls over rough surface. Tires provide a footprint called a contact patch that is designed to match the weight of the vehicle with the strength of the surface, it rolls over by providing a pressure that will not mark the surface severely.

A bicycle tire consists of three basic elements: the carcass, the bead core and the rubber tread. Almost all tires have a puncture protection belt.There are three types of tires you can choose from to put on your road bike, though some of this decision depends on the type of wheel one plan to buy. They include clincher tires, tubular tires and tubeless tires.

Before you attempt fixing a flat tire on a bicycle, it is helpful to recall yourself with parts of the wheel. The majority of bicycle wheels you are likely to encounter are comprised of four parts:

  • The tire.
  • The inner tube.
  • The wheel itself, which includes the hub, spokes and rim.
  • The rim strip.

Check the tire condition regularly

  • You should change the tires when you notice a change in the way the bike handles, or at the very latest when the tread is worn down to the wear bars.
  • Under-inflated tires will overheat and may fail. Over-inflated tires will give less grip.
  • Ideally, check tire pressure before and after every ride. Commit to a weekly checking routine.
  • Replace the tires if there is rapid pressure loss.
  • Always change tires in sets. Both tires go through the same stresses and rigors of road riding.

Fix a flat tire

  • Position yourself on the non-drive side of your bike and either open the quick release or unthread tire thru-axle to remove the wheel.
  • Start by removing the wheel. Keep your bike upright, and if it’s a rear-wheel flat, shift your drive train onto hardest gear.
  • If your bike has rim brakes, which many mountain bikes still do, you may also need to loosen the brake.

Patching tubes

  • Find the hole by pumping tube with air, listen and feel around the tube for the leak, mark hole with chalk or hold under your figure, use the sandpaper or another abrasive to rough up tube around hole.
  • Apply glue to the size of a patch, centered around the hole, allow two to three minutes for glue to set, glue will turn cloudy
  • Make sure that the glue area is slightly larger than the patch
  • Hold patch between thumb and finger for about three minutes, time taken now will ensure that your patch will hold later down the road, If at home place tube flat between two books and place heavy object on top.
  • Check to make sure that the patch bonded to tube all the way around tube will keep glue from sticking to inside of tire.
  • The Patches can last forever if properly applied.
