So which car tire is better? OE or aftermarket? Also read about car tires and how it is designed to improve rolling resistance and hydro planning.

Since the invention of the tires, the car tires have undergone and are undergoing tremendous technological changes. The research is continuously on to improve the performance of the car tires.The tire technology today enables Columbia shuttle to land properly and Michael or Kimi to hit 300 plus mph in their F1 cars. How many of us love that sound of those fiery F1 cars zoom past us. And then, more than once we have seen the races being lost because of failure of car tires.

Let us see what the researchers are concentrating in the technology of car tires.It is always presumed that the car tires must run smoothly. That means the rolling resistance shall be the minimum. If it is achieved, the fuel consumption of the vehicle is reduced. By using silica effectively in the tread compound of tire, the rolling resistance is reduced dramatically.

Michelin was one of the first companies to address to lower rolling resistance. Their Energy range of car tires were said to have low rolling resistance. A decade ago, the car tires were designed with open block pattern to take care of hydro planing. While hydro planing is taken care of, the noise was higher. With the computerized tire modeling the tire engineers are able to calculate the optimum pitch sequence of the tread blocks. They are able to arrive at the optimum contact patch of the tires as well. With the new design and new compounds, the tire engineers are taking care of reduction in noise.

The car tires were traditionally designed to be part of Original Equipment (OE) that come with the vehicle. The car tires have to under go more than 50 tests to get approved as OE tire for an automobile. However there arose a need for aftermarket tire which may be needed as a replacement tire once the life of the car tires that came in as OE.

Are these After market tires exactly same as OE? They may not be. They are close to the OE tires and your tire dealer knows more about these replacement tires. They can suggest you depending on the vehicle, model and the make of the tire. However we must appreciate that these replacement car tires are also very effective in the sense of rolling resistance and noise. Hence you can confidently use replacement car tires or discount tires.
