No experience, just opinions & observations. Love the classic look and they *should* have great traction. The page you linked had virtually no info as to specs, though. Probably a bias-ply tire so it will ride worse and wear out faster than most radials. If it has nylon plies, it will flat-spot when parked. As a plus, bias-ply tires generally have greater resistance to sidewall punctures than radials. It could be the best choice for a working 4x4 as long as you're willing to live with a few disadvantages.
