Thank you for the info, I just got a V85TT adventure. The recommended pressure for a V9 Bobber is 42 rear. You'll need a new spine installed very soon if you ride through NYC. Anything over 36 in the rear is way too much. This goes to tell you, the manufacturer isn't always 100% right.
for that type of tyres (off road tyres or fake off road tyres :) ), MG suggest 2.5 bar at rear anche 2.3 at front, for road tyre MG suggest 2.8 bar at post and 2.5 bar on front. I have 11 000 km and the wear is good
Have you tried looking at conti's? They are getting great reviews everywhere... www.continental-tires.com/motorcycle/tires/motorcycle-tires/off-road-enduro/contitrailattack3
