I reached out to banshee, they didn’t seem concerned with maxxis 2.5 or 2.6 on a 35mm internal rim.I’m running a 2.5 Aggressor on 30mm Bonty rim in the back.
I’m also running a 2.4 DHR2 on a Spank395+ rim (35mm inner)
Both these Maxxis tyres fit well. I did try a 2.6 Scwalbe Hans Dampf but it didn’t leave a enough clearance for mud.
I’m in SoCal, mud clearance considerations really isn’t a thing here. We (or I) don’t ride if it is wet to too muddy still, the high clay content makes things a sticky nightmare no matter what tire, plus it totally wrecks our trails.
I’ve decided on the spank 395 and aggressor 2.5, I’ll see how it inflates. But it works really well in SoCal for a rear for 85% of trails in a 100 mi radius. I even like the aggressor at snow summit when I’m sticking to west ridge and party wave. While I’ve used reckons in 27.5x2.8, I’ve just grown to like the aggressor more as a rear.
