It usually isn't.
But it depends on what you need most - good traction or low rolling resistance.
Usually, people try to leave the tires just hard enough not to get pinch flats. This gives the smoothest, softest ride and the best traction. But it can also be quite heavy to power the bike forward.
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.
MTBs are built to take rough riding, running across bumpy ground etc. Jump hard enough and the wheels run a risk of getting damaged, but the tires should be good for a lot of abuse.
The difference is that the mountain bike tube is much burlier and wider than the dirt jump tube but may not be as strong in terms of hard hitting strength.
It is not very hard to put full downhill on a normal mountain bike but you need to take it to a professional.
Yes, a bike will work in space. If it is a mountain bike it will work perfectly on the moon, but the tires may burst because of the pressure change in space. Since there is no oxygen in space, you can ride a bike perfectly, but on the moon there is no gravity so the bike will go faster and you may even fly with it. If you are pedaling hard there will be more resistance, if you are going slower the bike will ride smoothly just like on Earth.
When you're braking hard, trying to climb a steep hill or turning hard.
Directional tires are ideal for hard surfaces in good weather conditions. The best tires for driving in snow are snow tires.
For riding on hard, smooth surfaces narrow smooth high pressure tires are used. For riding on soft, uneven surfaces wide knobbly low pressure tires are used. For conditions in between tires in between are used.
ya it has a lot of speed and a good bike to learn the clutch on. The only porblem is hard to start the first time
It is a really hard bike to find, I'm not even sure if they still make them anymore. One site to try might be XtremeBestPrice.com, they sometimes have hard to find bikes at really low prices.
When purchasing a dirt bike it is important to look at certain features, whether the bike is set up for more hard or soft terrain, the engine size, what upgrade are available, what time of customized parts are available like grips, pedals and exhausts. Also a good feature to look at is whether or not is has elevated tread blocks.
That's really asking for too much versatility. A cross country(XC) hardtail (HT) with a suspension fork with lockout together with some slick tires will do decent on the road, but not comparable to a real road bike. And while a bike like that with some knobblies will do fine on singletrack it will not really stand up to "hardcore mountain biking". And whie something like an All-Mountain full suspension will stand up fine for some "hardcore MTBing" it will really suck if used for long road rides.
