I can give you a specific example in my case. I have run DHR II/DHF 27.5" in 2.8, 2.6 and 2.4 (exo casings) on 30mm and 40mm rims.
I am a certified lightweight (sub 150 lbs) hence the EXO casings; but I can definitely notice the difference so I imagine that would be magnified for a heavier rider. All of these tire widths feel good on 40mm rims, only the 2.4's feel good on the 30mm rims. This is mostly North Shore riding but also includes jumps and other reckless riding. Hopefully that helps your decision.
