Do you have 16" rims?
215-85R16 are the closest in size (outside diameter and width) to the original bias ply tires (700-16).
They're normally found as light truck tires (LT 215/85R16)
Brand is up to you. Find a tread and sidewall design you like. They can be found for about $100 each up to $300+ for aggressive off road treads.
If you want a bias ply appearance, look at Diamondback Tires. High quality radials with vintage look and excellent quality and handling. Not cheap.
