It all depends. A knobbly tyre will have a poorer grip on a smooth surface than a smooth tyre, while a smooth tyre will have poorer grip on a loose surface than a knobbly tyre.
But overall a smooth-tyred road bike, on a smooth and clean road, can brake and corner harder w/o skidding than a bike with knobbly tires can.
On true ice, MTB tyres are only a little better than road tyres. And that improvement comes from softer rubber. But what you really want on ice are studded tyres, something to really bite into the ice and create traction.
because the traction on the mountain bike tires have more of a grip to be able to ride on a mountain when a road isn´t that hard to ride on and to need more traction.
A mountain bike is made to be ridden on rough terrain so it has tough, knobby tires; a heavy, strong frame; and shock absorbing features. A street bike is designed to be ridden or smoother surfaces, therefore it has smoother tires, a lighter frame and lower handle bars so you can see hazards more easily.
Because new tires give a better ride and more grip on the road.
The more rubber on the ground = more traction or grip for the cars e.g. more speed.
Depends what laptop and what mountain bike and the deals you're getting for them.
low tires cause drag and it takes more to push these tires down the road. most bikes run about 40psi.
They grip more road surface.
Buckshot tires are best used on vehicles for off-road driving. These tires are more durable and have better grip on a variety of terrain compared to regular tires.
Rubber is used to make the tyers of car because rubber provides more grip or we can get more and more grip using rubber and wile diving car we nedd very good grip.
Michelin makes many different tires and they do cost more than other brands, but are well known as excellent tires for grip and mileage.
You would increase friction so that you wouldn't slip, by using the brakes on your car of bike you increase friction to stop yourself. Hikers increase friction between their feet and the ground by wearing hiking shoes that grip the ground better. Tires on cars that create more friction make the car go faster, because instead of sliding, the tires grip the ground and push off.
Kinda-sorta, but it'd depend on how finicky you are, and what bike you're talking about. A "real" road bike will often be built only to take narrow, high-pressure road tires, so a wider, softer terrain tire just won't fit in the frame/fork. But if your bike has enough room for wider tires, then there are "terrain" tires available for most of the wheel sizes used today. The biggest selection is in the 26" AKA 559 mm ETRTO and the 28" AKA 700C AKA 622 mm ETRTO sizes, where you can find tires for just about any terrain. Spiked/studded winter tires, tires for gravel/hardpack, mud tires, and so on.
