Instead of using steel belts (the way a radial tire does), the tire is entirely rubber.

What is a Difference between a bias - ply tire and a radial tire?
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.
What is the problem with bias?
Bias ply tires? They do not last as long and do not provide as much grip
What are the three belting systems available for tires?
bias ply, belted bias, and radial.
When is it legal to mix cross ply and radial ply 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.
Why do bias ply tires have high rolling resitance?
Because bias ply tires are constructed with more material than radial tires. More material means less flex which equates to a higher rolling resistance.
What are the manufacturing processes of radial ply tires and tubeless tires?
manufacturing process of bias & radial tires
What year did NASCAR make the transition from bias-ply tires to radial tires in the Cup series?
1995
What is meant by star rating for ply in Off the Road tires?
The load capacity of a tire is indicate by the star rating (in case of radial tire) and the ply rating (in cse of bias tire).
Is it safe to use radial tube with non-radial tire?
You can use a radial tube in a bias ply tire BUT you can not use a bias tube in a radial tire. The sidewall flex of a radial tire is greater than that of a bias ply. A bias tube cannot flex as rapidly as a radial tube and so the resulting friction or rubbing create too much heat and the tire/tube combination will blow.
How bad will bias ply tires decrease gas mileage?
The rolling resistance to be overcome regardless of tire type at 55mph requires under 10 horsepower of a typical passenger car. While bias ply tires do offer more resistance, the difference is extremely small - a bias ply may require the maximum of 10 hp, but even if the radial reduces this to the minimum, about 6 hp, the 4 hp difference will take a full tank of gas under exactly the same driving conditions to measure a difference in gas mileage. Gas mileage is not a valid reason, alone, to choose radial tires. However, noise, ride comfort, tire heat, adhesion, are all reasons not to use bias ply unless really necessary. In addition, Nylon bias ply tires "set" in cold weather and result in a "thump-thump" until they warm up.
What is the difference between 23.5-25 and 23.5R25 tires?
23.5-25 is bias ply tire 23.5r25 is radial tire
Can radial tires get flat spots from sitting to long?
Bias ply tires get a flat spot from sitting but I have yet to see a radial tire do that.
