Trim rings for a stock 15x8 6 lug rally wheel

[CRM318]

I have a 79' Blazer that has 31/10.5/15 General Grabbers on stock 15x8 6 lug rally wheels. I bought a set of 3in trim rings from Brother's Truck for it and they look great. Problem is, the bead of the tire works the ring off the wheel and makes a horrible sound doing it as well. I can pound them on and after a short drive, they are wobbly and about to fall off. I noticed that the stock 4x4 rallys have a different style ring with a bevel mid ring. These look like they belong on a Camaro/Chevelle. Is there a vendor out there that makes trim rings that work with all terrain tires? The beads are very close to the rim on my set up.

Afaik these are factory rings with older bfg ko's. Looks to me like the rings are perhaps not quite so wide to go past the wheel so there is no interference? Hard to really tell in the pic for me.
