Are 27.5 2.6 tyres designed for plus or non plus rims?
I have a SC Hightower with a flip chip to raise / lower the BB between 29 or + wheels. Currently it has 29 wheels with 2.3 tyres on it. I also have a set of 27+ wheels that came with the bike as well. The standard 27+ configuration for the bike is supposed to come with Minion 2.8 tyres.
Will there be any noticeable height difference between 2.6 and 2.8 Minions when used on a 27+ rim? Or would i be better sticking to 2.8
I can't see there would be a difference, but i've been wrong on less obvious stuff before.
Plus rims are 40mm by the way
2.6 are generally described as semi plus - which I think means basically designed for non plus rims, but I don’t see any reason why they wouldn’t work well on 40mm rims. I run them on 35mm rims and they work well on those. I can’t imagine they’d have a huge effect on geometry...but someone will correct me no doubt if I’m wrong...!
Just like most 2.8 tyres are smaller than that, most 2.6 tyres undersized.
I’m running a Hillbilly 29x2.6 at the front and a Butcher 29x2.6 at the back. I like them a lot, especially the Hillbilly. On a 30mm rim, Butcher casing is 62mm, side knobs 60mm; Hillbilly casing is 59mm, side knobs 61mm.
I went from 3.0 to 2.5 on my plus bike without noticing much difference in BB height. Mine was a rigid fork if that makes any difference. I put on Minion 2.6 rear and Shorty 2.5 front.
My friend has just put the same combo on his plus bike as well. The shorty came up big on my rim.
If its the Minion WT then this is designed for a 30 to 35mm rim.

Would the 27.5 x 2.6 Minion WT work well on a 40mm internal rim?

I think a lot of time its a case of trying it and seeing what you think.
I’ve been thinking of trying some Specialized 29 x 2.6 on 30mm internal rims, but the bike has a non-boost Pike - anyone know if they’d be compatible?
From my experience, and based on Nobby Nics EVO, the 2.6 is very very close to a 2.35, both in width and volume, the delta is no more than 2mm on the same 30mm rim internal. The 2.8 on the other is a genuinely bigger tyre in volume, width and circumference compared to the 2.6/2.35 "twins". The delta is twice as much if not more despite the official and meaningless/deceptive numbers.
In short the 2.6 is a normal tyre, not even an in between and the 2.8 a plus. The 2.8 fits my non boost Yari btw. I would add that 40mm is too wide for a 2.6 and probably not optimised for a 2.8, which works great on a 30 or 35mm rim.
Conti recommend 29-35mm rims for their 2.6 rubber.
2.6 Mary is much bigger than the 2.35 and a fair bit bigger than 2.5 Maxxis. It fits in my non boost 36s ok though. The tread blocks must be about 35 to 40 percent bigger than the 2.35 Mary.
I've got the 2.6 Specialized's and I really like them. I switched from the 2.35 just before a trip to BPW and it was like adding extra suspension.
Never measured them because I'm not bothered what the true width is. They look beefy on Hope 35W rims.
It's not even really a thing, you wouldn't think twice about a 2.4 or 2.5 and most of these are actually just that, with a different lie on.
ive got 2.6 buchers and purgs (can anyone tell me if the hillbilly is so much better than a bucher?)
and they are both 2.4 ish
