How does low air pressure in bicycle tires reduce the efficiency of a bicycle?

Flabby tyres produce more friction with the road.
Less air pressure creates more surface friction, the less surface friction there is the better. (Example look at the very skinny narrow tyres on road racers as they don't need a lot of surface friction while mountain bikes have thick tyres as they need more friction)

So, as altitude increases, temperature decreases. This means that as the bike travels up in altitude where it is colder, the pressure in the tires will decrease.

Why do bicycle tires generate less friction than car tires?
smaller cross-section of tread in contact with road
Why truck drivers are encouraged to monitor and adjust air pressure in their tires during long trips?
Proper air pressure makes for the best gas mileage. Too soft and it wastes energy. Too hard and the tires are not safe to drive on.
Why should tires be filled when they are cold?
Tire maintenance is best done when cold it is the closest to the actual pressure as air warms the pressure rises it may be as much as 10 pounds difference in cars so..... filling a tire warm will result in lower than safe operation pressure when cold.
What kind of glue can you use to glue rubber?
There are a few glues for rubber. The most common is found in bicycle stores to glue patches on tires. There is also a glue for gluing wet suits, available in Walmart, Sporting goods dept.
What measures the pressure of a gas or vapor?
Gas pressure can be measured using several different instruments including:Hydrostatic gauges - like a manometer or barometerPiston gauges - like tire pressure gaugesMechanical gauges - which use deflection of diaphragm, a capsule, or a set of bellows, which will change shape in response to the pressure of the region in questionBourdon tube - a type of mechanical gauge that uses a coiled tube (Bourdon tube) that deflects with pressureElectronic - including:Piezo resistive Strain GageCapacitiveMagneticPiezoelectricOpticalPotentiometricResonantThermal conductivity (conductivity of gasses changes with density - has to be calibrated to the gas)Ionization (best for low pressure gases - has to be calibrated to the gas)
How does low air pressure in bike tires reduce the efficiency of a bike?
low tires cause drag and it takes more to push these tires down the road. most bikes run about 40psi.

Is friction increased with inflated tires?
No, when your tire is at the optimum recommended pressure friction is least.- You will notice this most on bicycle tires, when pressure is low, it's harder to pedal. I pump my bicycle tires to 45 psi and have a smooth, fast ride.
How does tire pressure affect a car's fuel efficiency?
If your tires are under inflated the resulting "resistance" created will lower your gas mileage. However, if you maintain the correct pressure in your tires it reduces the resistance and improves your car's efficiency. It's also safer.
Do the cordless tire inflater pumps have enough pressure for larger tires?
Cordless tire inflater pumps are usually made for smaller, bicycle type tires or spare tires. Most of the time, these do not have enough pressure for larger, truck type tires. Best to use a compressor for these tires to ensure you are getting the appropriate inflation.
What should the air pressure be on a bicycle?
There is no single answer to this--bicycle tires vary a lot. The maximum p.s.i. should be written on the sidewall. "Fat tire" cruisers are frequently about 35 psi; the narrow tires on road bikes sometimes go up to 120 psi.
What keeps car or bicycle tires in the right shape when they are pumped up to high pressure?
the rubber is made to with stand the pressure to a certain point. hope dat helps
What material is used to manufacture Continental bicycle tires?
The material that is used to manufacture Continental bicycle tires is rubber made from the Uniroyal company or other companies that specializes in supplying rubber for bicycle tires. To get a more specific answer to the question, a visit to the local bicycle shop can render an answer.
When you ride a bike friction between tires and road heats the tires and air inside them how does this change the air pressure?
If all other things remain the same, a higher temperature means a higher pressure. For bicycle riding, the difference isn't enough to matter.
Is the air pressure the same in bicycle tires and car tires and why would it be different?
It is not the same, as car tires contain much greater volumes of air. The same amount of air that would raise the pressure slightly on a car tire could over-inflate a bike tire. Motorcycle tires typically fall in the middle of these tire sizes. A car tire contains a greater VOLUME of air at a lower PRESSURE. A bicycle tire has a lesser VOLUME of air at a GREATER PRESSURE. Some bicycle tires can be inflated to well over 90 PSI. The tires on my touring bike are inflated to 75 PSI. That's WELL over what should be in most passenger car tires. Some things to remember: When looking for the correct tire pressure for an automobile DO NOT go by what's printed on the tire, that is the MAXIMUM PRESSURE FOR MAXIMUM LOAD! YOU CAN CAUSE A BLOW-OUT BY INFLATING YOUR CAR TIRES INCORRECTLY! There is usually a sticker on the driver's side door jamb that tells what the pressure should be. OR CHECK THE OWNERS MANUAL Be sure to CHECK THE PRESSURE WHEN THE TIRE IS COLD! Oddly enough the CORRECT pressure, or range of pressures, is printed on the side wall of most all bike tires. It's important to check for the correct tire pressure on your bike to avoid "pinch" flats and to protect the rims and tires. It's normal for both car and bike tires to lose pressure if they are left standing for any time.
Why do bicycle tires need to be pumped up to higher pressure than car tires?
Car tires have very stiff sidewalls, that can carry some of the load. Bike tires are flimsy and have to do it all by air pressure. Besides, om a bike, with the power restrictions of its human engine, it becomes more important to keep the rolling resistance down as much as possible.
How do you tell age of bicycle tires?
Basically, you can't. Car tires comes with year of manufacture printed (in code) on them, but no such thing for bicycle tires. What you can do is judge them for dryness, mount& inflate them, and look for cracks.
