Radial tyres have much better stability, better road surface contact, better handling, more comfortable ride and lighter. Most commonly used on road cars.
Cross ply are cheaper and stronger, better grip for off road use i.e. tractors.
They are the predecessor to radial tyres on cars.
Radial tires are worlds beyond bias ply tires. In radial tires, the steel chords are placed in a criss-cross pattern. Whereas bias ply tires are placed flat across the face of the tire. Bias ply tires are much, much harder for the engine to turn and are much harder for the suspension to compensate for. Bias ply tires are almost no longer used. That goes for America at least.
Radial tiers have a lower rolling resistance than previous types of tire Resistance is energy, in tires resistance creates heat. Radial tires construction and the materials they are made of create less heat and roll easier. And if you need a more detailed explanation you need to look at Bias Ply tires (called Cross Ply in some countries) and Radial tires to see why it makes a difference
A radial tire is different from a normal tire in that a radial tires athatre built to last longer. The main difference is that radial tire have wires or cords that radiate at a 90-degree angle from the tire rim.

Bias tires were the standard until the radial tire became the norm. The difference is in how they are constructed. Bias tires were typically constructed of 4 plys that run at angles to each other and the body of the tire and cross each other. Radial tires have the belts at a 90-degree angle to the tire, and the belts overlap rather than cross each other. Radial tires have another belt, usually of steel cord, running around the tire under the tread. Radial construction allows the sidewall of the tire to flex under loads without affecting the contact of the tread with the road unlike a bias tire that flexes very little. It is this flexing that requires you to use a radial tube in a radial tire. The tube is designed to handle the flexing without overheating as a bias tibe would.
No, do not mix bias tires with radial tires.
Radial tires are better for freeway/street driving. They grip the pavement better and have better gas mileage. Cross ply tires are good for off-roading and any other kind of rough travelling.
Unless the tires are directional (indicated by an arrow on the sidewall), radial tires can be cross rotated. On FWD vehicles the front tires are moved straight back and the rear tires are crossed to the front. On RWD vehicles the rear tires are moved straight to the front and the front tires are crossed to the rear.
manufacturing process of bias & radial tires
Bias ply Tires (called cross ply in the UK) due to the construction of the internal belts actually had the trad squirm as the tire went around. Radial tire construction corrects this problem. Radial tires are also made of more advanced "Rubber" compounds that wear better
difference between a/s and a/t tires
Legality has nothing to do with it. Safety is what you should be concerned with. You should never ever mix Bias & Radial tires on the same vehicle. This will cause the vehicle to handle in an unsafe manner. The handling characteristics of Bias Ply and Radial Ply tires is so very different that it is unsafe to mix them.
