Logical way to look at it. According to that they are either 107 or 109 which on theory would mean there okay. I know heaps of folks have run them before on Transporters but it would be good to know for sure.
Kerb weight is about the same so you would expect them to be fine as well. I won't have any loads in mine.
Tempted, just need to check out best 19in tyres.
