A couple of suggestions
– Maxxis Advantage 2.1″ 62a/eXception (folding) = 595g
Quite chunky (Chunkier at the edges), some ramps and roll okay
– Bontrager mud X (TR, folding) 2.0″ = 550g. Softer compound than ACX’s. Roll well for a mud tyre. More of a racing mud tyre than a trailraker so work well year round. Nice to have in wet summers. Only downsize is they’re not very big in volume so pumped up don’t give you a lot of give when trying to jump (even small stuff)
– Kenda Nevegal 1.95″ DTC-lite = 580g
Kenda come up quite big so a 1.95″ should be about a 2.1″
Not a mud tyre so do block up in thick mud but generally okay. Not overly chunky but lots of rolling ramps.
DTC = Dual compound so harder on the rolling edge, softer edges
I’ve not used anything else similar that fits what you’re after or hasn’t been mentioned I don’t think
