Tire Pressure

I find it depends on the total weight carried. I'm 165 lbs and with no extra luggage I set 39 psi on the front and 40 psi on the rear.

Says 42 for both in the manual. Mine came from dealer at 40 psi front and rear.
 
I run the Cobra Chromes on my rocket X. Two sets so far and really like the tires. Run mostly open highway at 41 PSI front and back.
 
Been happy w/ Cobra Chrome's at F/R --> 36/42 ...and because I'm forgetful, I just set all of our bikes to the same F/R pressure (HD Fat Boy and V-Rod Muscle) without issue.

At the recommended 42/42 I find it a little stiff and can feel every bump I hit resonate through my back and neck. At 40 rear and 37-38 front it's a much smoother ride for my weight of 185lbs. I really like the Cobra Chromes.
 
Hi I find this quite an interesting take on an age old problem....three weeks ago I replaced both tyres with new cobra chrome and the tyre technician introduced me to his interpretation on tyre pressure which puts 40 in the front and 38 in the rear. His rationale was around the front doing the majority of the braking and with a heavy bike travelling at speed with the weight of a rider also in the mix the front tyre is less likely to distort with slightly more pressure in it. I must say that this set up feels better than I remember my first set of tyres did.....just a thought
