Can 25mm tubeless tires fit on a wheel that previously had 22mm tubeless tires? I have a set of wheels that previously had 22mm tires on it. There is no description of tire compatibility listed on the wheels.
I recommend tracking down the rim manufacturer's recommendations. Standards for road tubeless are still not completely settled, and manufacturer don't even agree on what makes for a safe setup. Tolerances are tighter than with tubed setups, and as this case suggests, putting on a tire that is a fraction of a millimeter too wide may result in a blowoff, which can be catastrophic.
That said, a 25-mm tire is not very wide. It's hard to imagine any rim manufacturer building a road rim these days that would be incompatible with it.
If it's any consolation; my road and gravel bike share the same wheelsets. All four sets are set up tubeless, have an inner width of 24mm, and I have mounted many dozens of tires on them. Sizes ranging from 700 x 23 up to 29 x 1.8" and everything in-between. No burps, no blown out beads, no problems other than changing out sealant, and re-taping the rim beds about every 2 years.
