Improved Radial Tires
Why Did NASA Make This
How Does It Help Us Today
There are some good advantages of a radial tire, and I am going to talk about some. Radial tires have flexible sidewalls, reduced fuel consumption due to less rolling resistance, a softer ride because of the layout of the tire's plies and because of the flex of the sidewalls, assuring more stable contact with the road service and a softer ride, less vibration, and extended tire life due to less heat generated by the tire.
The disadvantages of the radial tires are poor transport handling, since low lateral stiffness causes the tire sway to increase as the speed of the vehicle increases, increased vulnerability to abuse when overloaded or under-inflated. The sidewall tends to bulge which could cause damage and puncture, a ply layout that causes the radial tire to follow a wheel track more consistently than a bias ply tire, he radial tire is more expensive than a bias ply tire which may be considered as a disadvantage. The radial tire is more expensive than a bias ply tire which is kind of a disadvantage. However, the radial tire lasts longer and this results in the savings of money over the long run.
