If you true tires anyway, the smaller size works great. I use 44mm rears and 42mm fronts. On the rears, the "Granite" is the same as a CRC Grey-Low.
Here are some steps I used when I ran Jaco's in the past. I think the problem is a substandard adhesive used to mount the foam.
1) peel up the outside edge right out of the box (5-7mm wide).
2) apply 3M weatherstrip adhesive with a small screwdriver or scrap lexan.
3) massage the edge to get full contact.
4) after it cures, super glue the rim seam and sidewall.
5) shape the sidewall on a truer. I go for a 15* angle back from the rim and then liberally radius the shoulder of the tire.
Frankly, Jaco's are a pain in the @$$. This seems like a lot of work, but we don't have those damn brushed motors and round cells to maintain anymore do we?
I do steps 4 and 5 from above on every set of tires I run. Consistency pays off at some point? Or, it should, I think?

Honestly, this is the first I have heard about our tires peeling. I'm not saying it hasn't happened (obviously it has if you say so), but in the thousands and thousands of tires we have made, I had NO idea it was an issue. You mention that the first thing you do when you get our tires is "peel the outside edge 5-7mm". How is this possible? I just went into the back and took 50-75 tires and tried to peel them. There was no way the foam was coming off. We roughen every wheel and then use super glue to bond the foam to the wheel. This doesn't mean that from time to time a few tires get through that aren't glued as well as others, but it would seem to me that if it was as much of a problem as you say we would have heard about it. Since we warranty tires for coming unglued, and we have not had any returns, I would have no way of knowing this was an issue.
By the way, we intentionally make our wheels more flexible to prevent breakage. Trust me, it is much better to have people complain about flex than to have them be upset about breaking a wheel. We don't feel the flex compromises the performance so we tend to lean towards caution.
