Innertube Replacement
 
Yep, this is my tyre, I did a ride to Blackpool for Christies Hospital - Charity Run and got home,
pulled a piece of grass off my wheel and a HUGE thorn attached to the grass came out and all of the air escaped too!!
A perfect opportunity to do this section on here. This Guide will work for most types of bikes.
 
Ahh, a popular sight after a Puncture.
 
So, undo the bolts on the wheel, and release the brake
remove the wheel from the bike.
 
Let the rest of the air out via the valve.
With Presta unscrew the little metal stopper and push the plunger.
Schrader press the plunger in the case.
 
Use a plastic tyre lever to remove the tyre, as not to damage your wheel or your tyre,
or the innertube if you plan to repair the tube with a patch.
 
 
 
 
Then use another tyre lever to guide around the rim of the wheel, and remove one side of the tyre from the rim.
 
Tyre Off - Tube In
 
When the old tube is out, check there are no sharp bits left in tyre with your fingers,
 
there is nothing worse than putting a new tube in and then pumping it up, then it go down again!!
 
Pump up the new tube slightly first so it looks round not flat, then push the valve through the hole in the rim.
 
Then tuck the tube inside the tire, putting the valve in first keeps the tube the right way all the way round and stops it getting kinked.
 
Push the tyre back round the rim, this can be a little tough so you may need the tyre levers but it will go.
 
Once it is back in pump the tube up a little not all the way yet, check the tyre is level all the way round on the rim, and snug.
 
Pump up the tyre (pressures depend on tyre type), I pump mine to 40 - 45 psi.
 
 
 
Again check there are no bulges or part of the innertube poking out, insert the wheel back on the bike and tighten the wheel.
 
Dont forget to reconnect the brake you took apart at the begining.
 
And its done . . . . Happy riding . . . .
