Thanks for the reply. Still interested.
Would something like a 2.5WT Maxxis DHF be to small of a diameter and thus maybe lowering BB too much? For my riding areas and speed I find I need a more robust casing (DD or DH) and cushcore in the rear. Looking to see what kind of tire options there are in 27.5+ and there isn't much for DH or double down type stuff. I see WTB has 2.6" options in TCS tough which is a good casing. 2.6" wide enough for proper diameter and intended geometry?
If you want a tough, sticky tyre that won’t let you down try a 275 Magic Mary DH Ultrasoft 2.6. I ran mine with 27psi in the rear. I weigh 73kgs all kitted up so depending on what you weigh you may need more or less. It is a heavy tyre but I have never had a pinch or puncture and believe me I have been through a number of serious rock gardens and have always come out the other side unscathed.
I am currently running a 2.8 Eddy Current with a Super Gravity casing on the rear and this is possibly another option for you? I have only been on two rides so too early to comment apart from it appears to handle the rock gardens pretty well too with 27psi.
Hope this helps
