You have a valid point, "that the sudden blowout leaves a no win situation". I am trying to monitor the wear factor and slow leaks that creep up on you in both the RV and toad which I would prefer not to have turn into a failed tire. We have brand new tires on now and hope to gain many miles on them. And not to mention the fact of fuel savings is a nice way of re-cooping monies spent. I think that $820 is a small price to pay for maximizing family safety. But I don't think it to be the pressure checks scenario as it would be those times when weather for one would make that task a bit bitter.
