OK im about tobuy new tires for my 74 blazer. I found a very good deal on Super Swamper TSL/SX's and my question is- They say that the tire is a "steel belted tire" does this mean that it is a radial? or if its not what is it? What is the difference between a radial and non radial tire? I do alot of wheeling,but I also drive every day on the street, Will the TSL/SX be ok? or bad?
