I have put my 27,5 on my 2019 Levo. I run the 2.6 Butcher in front and 2,6 Purgatory in the back. These tires because I haven´t shifted theme since they were on the rims from my original bike. What I found out was where I ride even the tiny pattern of Purgatory in 2.6 work just fine when it comes to grip. Would like a more precise cornering tire though, but still...I ordered 2.6 Maxxis DHF and DHR in 27,5 now which I belive will be plenty of grip and better when it comes to cornering. The BB hight comes in around 330mm(3mm higher than Stuntjumper EVO) now in the low setting. The frontend feels a little bit low so ordered a 160mm air shaft to the front end to raise it up a bit. I think the bike would be fantastic with "normal" 27,5 wheels with 170mm up front....The handling is 10 times quicker and more fun than the 29". The low BB is just noticeable on a slow step down but works great on slow step ups when it comes to hitting the motor and battery...You also need to plan a little bit more where to paddle for not hitting your krank arms but I really prefer that than a high BB
