Step in Line: Pay close attention to alignment--shaft drive bikes have no adjustment, but if you have a chain or belt, check the position of your tires. Proper alignment ensures better handling and longer wear.

Remember cold weather means air in the tires contracts and may require additional air. High temperatures, hot or rough road surfaces, high speeds and heavy loads all cause the tire to work harder and hotter. Make sure tire pressure is sufficient to deal with these conditions. Also under inflation is the number one cause of tire failure.

When inspecting your tires check the tread wear indicators (TWI), which are noted by the TWI (some tires may display logos etc in place of TWI) marking located on the tire sidewall. Look towards the center of the tire to locate the actual tire wear bar which will be located in the tread groove itself, as a raised bar. When the tire is worn to this indicator it is time for a new tire. We have actual samples of worn tires to show you the amount of skin left between you and the road so to say. It is scary. The remaining amount of rubber is actually less than is apparent from the outside.

Hydroplaning is the effect when the tire rides up onto the water surface of the road. What effects this is both the remaining thread depth, speed of the motorcycle and the amount of water on the road surface. In wet weather slow down and before going on a long ride for safety sake replace your tires if they are near the wear bars...its your skin.

Tubes should always be replaced as these will wear just like the tire itself. When installing tubes be sure to locate the valve stem retaining nut all the way to the top of the valve stem so that it touches the cap. This way if the tube spins inside the tire you can see this by the tilt of the stem before the stem is torn from the tube itself. On tubeless tires always inspect the valve stem for cracks and dried out rubber, since these can crack over time and leak air. This thinking applies to car valve stems as well.
