It really doesn't mater as long as they are all the same.
No, do not mix bias tires with radial tires.
no
manufacturing process of bias & radial tires
You should get radial tires because if you go to www.mud-throwers.com it lists all of the disadvantages and advantages. So you should spend a little more money on the radial tires.
It's not reccomended.
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.
bias ply, belted bias, and radial.
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.
Bias ply tires get a flat spot from sitting but I have yet to see a radial tire do that.

No, it gives messy handling.
Quite possibly. The radial tire was invented in the 1940's and became widely used in the US during the 1970's. Radial tires should not be confused with steel-belting which is used to strengthen the tread resistance to puncturing in both radial and the older bias-ply tires.
