27.5+ on the rear, 29 on the front, naturally. :)
This. I experimented 27.5x2.8 with my Rootdown BA back in 2016, found the bb too low and too many pedal strikes on the way up for what I was riding. But I really liked the increased traction out back and a bit of cush. I didn't like the 27.5 up front though, at least not at the 'proper' ~14psi, tire squirm and vague steering was a thing for me and my limited skills.
Once I jumped up to a 29" front wheel it raised my bb just enough, and running a 2.4/2.5 with proper 21psi was enough to get steering precision back.
I don't carve berms so that bit of tire squirm that I'm sure exists out back never factored in for me.
So you are running a 275+ in a 2.8 out back and a 29er 2.4/2.5 on the front?
