I seem to have run my last post together as I know the difference between the R-5's and a 2 or 3 piece wheel,you might call the r 5 a 2 piece wheel but I've never heard of it that way,in the big truck world of 10:20's or 10:22's those are called 2 or 3 piece wheels it depends on if there is one lock ring,wheel,making that a 2 piece wheel or a lock ring,wedge and wheel that being a 3 piece set up. And as I've stated I still run a set of r-5's on our 61 GMC 2 ton and my tire guy that has been working for a local tire shop for the last 35 years will still do those for me. But on other trucks I work on for customers I won't run them a snoone else will work on them.
