TIRES
Maintenance:
Frequently check the tire inlation pressure because all tires lose air slowly over time. For extended
storage, keep the weight of the bicycle off the tires.
WARNING:
Do not ride or sit on the bicycle if either inner tube is under inlated. This can damage the tire and
inner tube. Do not use unregulated air hoses to inlate the inner tubes. An unregulated hose can suddenly over
inlate bicycle tires and cause them to burst.
Use a hand or a foot pump to inlate the inner tubes. Service station meter-regulated air hoses are also acceptable.
The correct inlation pressure is shown on the tire sidewall.
Before adding air to any tire, make sure the edge of the tire (the bead) is the same distance from the rim, all
around the rim, on both sides of the tire. If the tire does not appear to be seated correctly, release air from the
inner tube until you can push the bead of the tire into the rim where necessary. Add air slowly and stop frequently
to check the tire sealing and the pressure, until you reach the correct inlation pressure as indicated on the tire
sidewall.
Replace worn or defective tires and inner tubes.
TIRE REMOVAL
1.
Let the air out of the tire by depressing the valve core (the little pin
in the centre of the valve stem opening).
2.
Separate the tire bead from the sides of the rim by pressing with
your thumbs. Work your way around the tire on both sides to be
sure that the beads of the tire are not sticking to the rim. (Figure A)
3.
Stand the wheel up on a irm surface with the valve stem on the
bottom and grasp the upper part of the tire with both hands. Try to
roll the tire off the far side of the rim.
4.
With the wheel standing as in Figure B, use bicycle tire tools or
spoon handles with rounded ends (at least two - preferably three)
to lift the bead on one side of the tire off the rim. Be careful not
to pinch the inner tube between the tire tools and the tire bead or
rim. Once you have got the bead off for about one fourth of the
circumference of the tire using the tools, the rest can usually be
pulled off by hand.
5.
With the bead on one side of the tire completely off the rim, you
can now pull the inner tube out from between the tire and rim
everywhere except in the area of the valve stem.
6.
It should now be easy to pull the tire the rest of the way off the rim.
Start at the side of the wheel opposite the valve stem and simply lift
the bead of the tire up over the side of the rim and pull it off.
