The 2022 rules brought in 18' standardized rims. So 2022 was new, they improved some for 2023 and 2024. Then opted to not change anything in 2025 from 2024, they opted to focus all that for 2026. It can't be the guys don't know how to remove a rim, it's getting stuck that's a hardware problem. They got to figure out why it's getting stuck and prevent it. I don't know if they have to use different materials, rim ejection springs or what but the rim has to come off fast. Someone should ask Cowell "Dude, what's with the rims getting stuck all them time?" HOPEFULL, he'll say it's a known problem we'll fix it next year.
I also wanted to add that they made the softs of the first stint last the laps that a first stint mediums would and they made the mediums of the 2nd stint last the same number of laps as a 2nd stint hards would. The first stint was significantly slower than the leaders but in the 2nd stint they had similar pace to the leaders.
I saw a post somewhere else, analyzing the Singapore pit stops, and what surprised me was that it mentioned AM use Mercedes pit stop equipment.
It's a surprise that they still use it, especially after Toto openly admitted that he doesn't see the investment into improving pit stops as worthwhile, back in 2021.
The rims and the nuts are standard in F1. Would make sense that the guns are too, not sure about that. Narrows down the problem for us doesn't it? Has to be the hub side. They do invest in that alot!
It can be something related to manufacturing tolerances. From a slip fit to a tight fit is easily achievable with brake-like temperatures (as in mounting hot bearings in a shaft at room temperature).
Edit: And what are the tolerances for such spec rims?

Is always well known that even in spec series not all teams run with exactly equal engines. And furthermore, how are handled by the manufacturer the sorting of "not so perfect' parts (we are talking about a pair of hundreths of a mm to get from slip to tight).
