TIRE REMOVAL
Most tires can be removed and replaced by hand. Be careful, pinching the tire tube can easily put a hole
in it even if you are using tire tools.
1 Remove valve stem cap.
2 Release air from the by depressing valve stem.
3 Tire should be loose in the rim.
4 Place wheel on floor.
5 Grasp tire with thumbs and fingers of both hands.
6 Lift tire and slide over one side of rim.
7 While holding the with one hand, peel tire off of wheel rim with other hand.
TIRE INSTALLATION
1. Position tube inside of tire casing.
2. Insert tire valve stem into hold in rim.
3. With tube inside tire casing, roll tire casing onto rim. Be careful not to pinch tube, and be sure that
the tube is not twisted in the tire.
4. Hold valve stem while inflating tire to pressure specified on side of tire.
TIRE INFLATION TOOLS REQUIRED – HAND PUMP & TIRE GAUGE
Tires make a big difference in the performance of your bike. When properly inflated and maintained, your
tires will give you many miles of wear and service. The following are tips for proper maintenance and care
of tires and wheels.
WARNING: IMPROPER INFLATION IS THE BIGGEST CAUSE OF TIRE FAILURE. DUE TO THE
SLIGHTLY POROUS NATURE OF BICYCLE INNER TUBES, IT IS NORMAL FOR YOUR TIRES TO
LOSE PREESURE OVER TIME FOR THIS REASON, IT IS CRETICALLY IMPORTANT TO MAINTAIN
THE PREPER TIRE IN FLATION ON YOUR BIKE.
1. Tire pressure is indicated on the sidewall of the tire.
2. Check your tire pressure before each ride by squeezing the tire between your thumb and fingers. It
should feel very firm, but not hard, when you sit on your bicycle, the tire sidewalls should not compress
very much under your body weight. Check your tire pressure at least once a week with a pressure gauge.
3. Use a hand or foot pump to inflate your tires. NEVER inflate your tires with an air compressor at a gas
station. Air compressors release a high volume of air under great pressure. This much air can explode a
bicycle tire and tube in a matter of seconds, and any may cause serious personal injury. DO NOT LET
CHILDREN INFLATE TIRE.
4. A bicycle tire will wear out faster when underinflated. An overinflated tire can become unseated from
the rim and blow out. Be cautious of both these inflation areas.
RECOMMENDED TIRE PRESSURE
BMX 241-344 k.p.a. (35-50 p.s.l.)
MTB 276-448 k.p.a. (40-65 p.s.l.)
Road Touring 483-620 k.p.a. (70-90 p.s.l.)
Road Racing 755-862 k.p.a. (110-125 p.s.l.)
Hybrid/Crossbike 414-690 k.p.a. (60-100 p.s.l.)
BEAD NOT SEATED OR OFF RIM
Deflate tire, seat bead with hands and partially inflate tire for inspection. If the bead is properly seated,
inflate to recommended pressure.
SEATING TIRE
After repairing or changing the tires, it is important that the tire is seated properly on the rim.
1. Run your fingers around the bead of the tire to insure it is inside the outer rim ridge.
2. Partially inflate the tire with a hand pump.
3. Inspect the tire to see that:
a) Valve stem is perpendicular to the rim.
b) Tire bead is properly seat inside the rim.
c) Spin tire to see if it is aligned straight on the rim.
TIRE NOT ALIGNED
Partially deflate tire, align using hands. Inflate tire to recommended pressure.
TRUEING WHEEL
Because this is difficult procedure, we suggest spoke adjustment be made by a qualified bicycle
repairman.
