What are cross ply and radial tyres?

Here is the information I found on the tyres: What is the difference between a radial and a conventional (cross-ply) tyre? The radial tyre is distinguished by the plies that form the carcase being radially oriented. This means that they run across the tyre from side to side, at 90° to the direction of travel. In a cross-ply tyre the carcase plies intersect and form an approximate 45° angle to the direction of travel. The result of manufacturing tyres with these quite different types of construction can be summarized as follows: The radial construction has a very flexible sidewall but a stiffer tread area. The cross-ply construction has much stiffer sidewalls with a more flexible tread area. The resulting performance of the different construction types is very important if we consider wear, traction and stability, particularly during road transport. Hope it answers your question.
