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)
Do rubber tyres show more friction or less friction?
Rubber will have a high coefficient of friction on most surfaces, but we cannot know whether there is more or less friction unless we have something to compare it to.
As soon as an object starts moving what replaces static friction?
Kinetic Friction replaces Static Friction when an object is in motion.
Why is it easier to pull a box in a wagon than to drag it on the ground?
I have the same question omg I don’t know how to answer
Anti-lock braking systems are very good on wet roadways with less then normal or little friction?
The anti-lock braking system usually reduce the skidding that occurs when tires lock and therefore allows the driver more control during emergency braking. Having the tires on ABS can help a stranded driver to veer away from emergency situations.
Which tires produce less friction?
Narrower tires with harder rubber

When a cars tires are stuck in snow or mud is it better to have more less friction and why?
It is better to have less friction because it will be easier to get out.
What are the benefits of radial tires?
Compared to previous versions of tires, radial tires have less rolling friction or less friction with the road while in motion. The result of this is that the tires are generally quieter when driving on the road than the previous version and also allow for better fuel economy.
When a car's tires are stuck in snow or mud is it better to have more or less friction?
More
Using the ideas about friction and deceleration explain using a new tire than badly worn tires?
New tires actually have less friction on dry surface than old, bald tires, but once the old tires hit water, you new tires quickly win.
How does friction on tires effect the stopping distance of a car?
The more friction, the quicker the vehicle will stop, meaning less stopping distance.
When a vehicle hydroplanes its tires?
When a vehicle hydroplanes, the friction the tires are against is something other than the roadway - typically, it's a layer of water between the tires and the roadway. As the water has much less resistance and friction than asphalt, the tires spin much more freely.

Why does f1 cars need to change their tires so often?
so that less friction is caused, and to improve speed
Are wider car tires better than narrow car tires?
Yes if you want better road holding. No if you want less friction and better fuel economy.
Does spinning tires in the snow give off thermal energy by friction?
Yes. But it will likely only melt a thin film of water, which will freeze and become ice the minute the tire stops spinning. Also, by stepping on the gas and spinning the tires rather than ease your way out of the snow, the tires have less traction. Reason is when the tires spin, you have kinetic friction between the tire and the snow. If the tire is rolling over the snow, you have static friction. Static friction is greater than kinetic friction. Point being: don't spin your tires if you want to avoid getting stuck.
