Mine are Power King Bias Ply (6 ply I think) and to tell you the truth, I can't remember if they're 7.50 or 7.00. I'll have to remember to look. any how, I got em' from a tire store that just had em' in the back. I was ready to buy spendy tires and he mentioned these. Brand new and only $50 each. I said hell yeh. They don't balance worth &%^#, and I had to pay another $100 to have em' shaved. That helped a little, but still not great on the open highway. Good in the dirt though.
