Road bikes have thin tires because they are operating on smooth surface and should be light.
bmx= small trick bikesmountain= small trails, thick tires (more dirty and muddy), fresher airroad= thin tires, faster speed, dealing with traffic!track= indoor circular track banked like this --> / (not that steep!) (about 300m circumference)Bmx Bikes are designed for trick riding and urban ridingMountain Bikes are designed for off road travel such as hills mountains, fields and tow pathsRoad Bikes are built for speed and long distance racing with lightweight frames and thin tires to reduce road drag.Track Bikes are similar in design to road Bikes but have no breaks and are designed for riding and racing indords on wooden tracks with curved banking,
Bikes styles all have different tires to suit terrain. There are road racing tires, cruising tires, off-road tires and many different wheel sizes too.
You could check at a local bike store. There are BMX bikes, mountain bikes, road bikes. The main differences are the types of tires, suspension, and brakes.
Smaller contact patch between the rubber and the road.
Road bikes are used on hard surfaces, where a slick tire will give the most traction/friction with the least rolling resistance. MTBs are intended to be used off road, where knobbly tires are needed to dig into the sand/dirt/mud in order to provide traction/friction. It's the same reason behind jeeps and 4x4 cars having much knobblier tires than ordinary road cars.
low tires cause drag and it takes more to push these tires down the road. most bikes run about 40psi.
Generally not, most don't have all the signals & tires are usually not d.o.t.
pocket bikes can be a little dangerous going off-road. they are not designed for that but if it is mild of road with not to many bumps, you could ride it off-road. if you want to put dirt tires and still ride on the road, that would increase its grip, performance and handling.
Cervalo Cycles makes lightweight road bikes, in two different categories: Classic Road Bikes and Aero Road Bikes. The bikes are tailored to be as comfortable and efficient as possible on the road.

Yes, you can technically put knobby tires on a street motorcycle but this is not recommended for street use. Sport bikes tend to be too heavy and difficult to control off of the road even with knobby tires.
