You'll have to assume that your geometry was how you wanted it.
I think the rears are similar, but the PRC is shorter. So, you might just drop your tubes a few mm to compensate.
There is a Pirelli site that has that info, but I could never get it to work.
That only accounts for the static geometry. The shape of the tire can be different enough to require more changes.
If it was optimized by one of the GMD people or 4&6, it might be worth calling them.
