A car tire has a square road contact, and the leading edge of the contact is a straight line. On soft, squishy surfaces, the knobs poke into the surface, digging in for improved grip. How then, do they transfer the load from the contact patch to the rim? Because the contact patch is flat against the road, the curvature of the sidewalls next to it is increased, decreasing their tension, and the angle at which they approach the contact patch becomes shallower.
Tires with v patterns are common for motorcycles, and are generally installed so that the point of the v hits the road first. If there was an audible bang, then the tire was off the rim, exposingthe inner tube. Airless tire schemes have also been used by con artists to gull unsuspecting investors.
Tubulars are used on special rims, and are held on to the rims by glue. There are three areas where traction is at issue braking, climbing, and cornering.

The question then arises, which way should they face? With tires for road use, it really doesnt matter, since tire tread patterns serve no function on hard surfaces. Tubulars used to be fairly common on high-performance bicycles, but these days they are an endangered species. The edges of the contact patch scrub against the road as a segment of the tread becomes shorter and wider where it flattens out, then longer and narrower as it becomes round again.
Air is pushing down against the bottom half of the tyre cross-section with a force of 100 pounds per inch of length. See the section on traditionally, each major bicycle-producing country had its own system for measuring and designating tire and rim sizes. This is a major oversimplification -- rubber is the least important of the three components that make up a tire the bead is the edge of the tire.
The high pressure of bicycle tires is more efficient at squeezing the water out from under. The trade-off with this is that the thinner the tire gets, the more fragile it is, and the sooner it will wear out. In self defense, coke would retaliate by marketing an even lighter 700-23 labeled as a 700-25.
