How to mount the front wheel.
How to properly mount the front wheel so the forks are in alignment.
Careless wheel mounting can result in leaking forks.
Replacing tires can be a little rough to get the hang of.
I've done it countless times and I still hate doing it.
Pinching the tube, a cut finger, a jammed knuckle, all potential rewards.
Not to mention a pinch flat when riding because you messed it up some how.
But, it is a necessary evil and doing it is a bit easier when you know the tricks of the trade.
Here are two videos to help you out, both by Dunlop Tires. One shows removal and the other shows install.
When installing the rear tire, work with the brake disk side up as much as possible to avoid injuring yourself on the sprocket teeth.
Remember to clean the brake disk(s) prior to mounting the wheel(s) to the bike.
A mixture of dish soap and water (about 50%/50%) can serve as a bead lubricant to make mounting easier if tire lube is not available.
Prior ro remounting a used tire (ex: you replace a tube), inspect the interior surfaces of the tire for protruding objects such as thorns, cactus needles, nails or what ever can cause a tube puncture.
When removing a tire and the bead will not break from the rim, a c-clamp can be used to squeeze the tire together to pop the bead from the rim.
Prior to mounting a tire to the rim, make sure the rim strip is in good condition. If a strip is bad and a new one is not available, an old inner tube can be modified to make a temporary rim strip. With a good overlap at the splice, rubber cement will make a good bond. Duct tape or electrical tape can also substitute for a rim strip. Duct tape, however, will leave a mess of glue on the rim surface that will be difficult to clean off.
Changing tires is always easier in warm temperatures.
After mounting is complete, you can use a solution of soap and water to check for leaks. Apply the soapy water along the tire bead, spoke connections, rim lock openings and valve stem. Note that some air gets trapped between the rim and tube during filling of the installed tire which will bleed out from rim openings.
