I have the same situation and I have just bought a deal on 6, like new 8.25x20 tires,tubes and liners. Mine are the 6 lug wheels.
I too have read the tech tips and all the bad stuff about the Firestone RH 5* wheels. But I have also read and talked to people who say use them.
Think about it: They must have put millions of those on the road over a span of many years. I don't know when they stopped making them, but every truck I have looked at from 1950's to 1966 have them, even F**rds, don't know about Dodge.
When I was a teenager I saw a man get the top half of his head cut off by a lock ring that flew off while he was airing up the tire. So, really it seems any 2pc. or 3pc. wheel has the same potential. I think it takes someone who knows what their doing to change them safely. Such as chains or a cage to air them up in. Anyway, since I have already bought tires, I have found a man with experience with the RH 5* and he is going to mount my "new" tires for me.
