For those who are considering reusing the RH-5 rims, ask yourself this:
"Which family member do you want to risk maiming or killing"?
As by stated John above:
"Running RH-5's doesn't pass a risk analysis. But more importantly, it's irresponsible. And we need to be better than that in this hobby. If you still want to engage in this hobby.
You want to run an antique Big Bolt? Great. Welcome to the Big League. Now put your Big Boy pants on, break out the wallet and do the right thing"
These things (Firestone RH-5) are not worth trying to save a few bucks, or prove a point.
No one here wants to see someone hurt or killed to save a buck.
So guys please, please find another wheel...they are out there, just take some time to look.
