I present to you the future of your Monkey, 650B+ 2.8" rear/29x3.0" front :-D If you want to keep/use a sus fork, then I'd go for a 29x2.6" tyre on i35 rim upfront if that will fit, but basically i35 rims built to 650B/29" hoops and tyres to suit. Running the mullet will slacken the HTA out by almost 1.5 degrees by my calculations when I did it.
Making this setup completely changed my '08 Monkey and make it a lot more "real" trail friendly, especially the steep stuff, it was so fun, but then when it was approaching 10 years old, I decided it had served me well and to replace it with an '18 Unit for more Reach and slacker HTA running 29+ F&R.
