Yeah, same here with tubeless, Maxxis foldy beads always (ime) have good quality beads and their sidewalls have a fair amount of rubber in so I’ve never had one that was even difficult to set up tubeless. If they just stuck “tubeless ready” on the standard ones I don’t think anyone would ever know tbh 😆
If in doubt, stick a minion 3C on the front. And don’t be afraid to go big, I can’t remember what sizes they do in 650b but even the redonkulous 2.5 29er is a perfectly livable-with day to day tyre.
Rears is much more a matter of taste though, some folks really like to have grip, others will sacrifice it for speed. DHR2 is good for grip, Ardent IMO reasonable for balance but some folks hate it. Haven’t tried a Minion SS but I have the specialized equivalent and it’s great fun and super fast but does have its limitations (it’s ****-all use climbing on wet rock, frustratingly so… It’s hilarious in descendy mud, I actually really enjoy it but it makes me slower.
