crests have gotten wider recently I think – I was using a Maxxis Ignitor LUST on a 355 but it is very difficult to get on a crest.
Crests haven’t changed, but they’re not just a rebadged 355.
The older rims (355, Flow, Olympic, Arch) were slightly smaller, the newer ones (Race, Podium, Flow Ex, Arch Ex, Crest, Alpine) with “BST2” or whatever they call it are slightly larger, which makes tyre fitting harder, and inflation easier. Slightly annoyingly at the same time Schwalbe made their tubeless ready tyres with a slightly smaller diameter bead, which achieves the same thing, but makes for tight combinations.
Crests for my money for sure.
