From the pics shown, those rims look pretty worn. unless those pics are deceiving me. I would pop on a new one.

One of them was the one that sat on the saw, the other is brand new.
I had the new mounted while cutting.

Eventually it will cause chain chatter , which will eventually damage the chain drivers & bar . Its also not good for the clutch bearing run out .dang, really? even if the rim sprocket sits fine on it?

It is hard to make out the metal from the shadows and finger.
Yeah , you can see the cupping , as Cookies also mentioned long term a new clutch drum & bearing will ensure long term satisfaction the crank bearing end play would require extensive involved testing . You should lubricate the clutch bearing at least annually also , more often in some applications .Ah I see, sorry.
Here are 3, one is used.
Their certainly have seen better days !One of them was the one that sat on the saw, the other is brand new.

Yeah, much better pic. Can you do a close one of the chain?
Good pick up on the chain drivers John they certainly are rounded off , my old eyes missed that obvious flaw lol.Yeah, much better pic. Can you do a close one of the chain?
As far as cross referencing parts , John has a wealth of knowledge in that and anything chainsaw . As for the clutch drum & components ensure to deglaze & degrease with brake clean . The needle roller bearing , ensure that needles are secure in their cage & roll smoothly also apply some assembly lube or appropriate grease prior to installation . Your in very capable hands with John & Cookies !I see.
I found a used one, from a Jonsered 2153/Husky 353, and a used spur sprocket from a Husky 55 (has wear, clearly sadly)
I wonder if I can fit one of those instead.
Also found a brand new bearing as suggested by @cookies
Edit.
The Jonsered 2153 drum looks in good condition, it is very slighty "wider" than the Husqvarna 254 one, I don't think it matters when fitting the clutch though.
Picture shows.
Jonsered 2153 drum, Husqvarna 55 used worn drum, Husqvarna 254xp worn drum. In that order.
395’s will teach a fella to tighten bar nuts moreIm no expert, but I'm just going to point out that the adjustment screw does not hold the bar and chain in adjustment tension, it's the clamp force of the clutch cover to the bar pad.
I often back the adjustment screw from tension once I tighten the bar nuts.
Clean the oil from the bar plates upon reassembly, tighten the chain properly , along with the bar nuts and next time the chain will bind right up on a defective bar, taking the guess work out of the equation.
Ive also had alot of used bars, and bent a few adjustment screws with a kickback.
