Ultra tire pressures
I ran my rear at 40 PSI for 22k miles before it had to be replaced with no cupping and my front at 36 PSI for 27k miles, also with no cupping. Some of those miles were done with an extremely laden bike; I'm guessing I was close to 1600 GVW for probably 5k miles of that time. Due to the amount of time I spend on the road, away from my home area on the bike, I will often (ever 2500 miles or so) pull into a dealership and have them check my tire pressure for me. It saves me from having to pay for air and I trust their equipment far more than I trust those paid air systems. Just my two cents...

40 psi front and rear for me too.
I remember reading back in '09 or '10 that increasing the front to 40 psi really helped.
I got 15K out of the front before my free replacement from HD
Take care,
Dave

I run the OEM Dunlops 2 psi over the owners manual stated amount.
I replaced the tires on my 10 Ultra with over 22,000 on them and the wear bars had not been reached yet. I didn't want to head out on a long tour with them and they weren't as good in the rain.
I replaced them with the same tire.
Dunlops in my experience over the years will cup a little unless the higher psi is maintained. Especially the front tire.

I have those funny valve stem caps that turn red when you go below a certain pressure...Kinda my TPMS program.

Throughout my 40-odd years of riding I have found that running tyres a little above recommended is helpful and that riding 2-up requires a significant increase in the rear tyre especially. No way would I ride 2-up on solo pressures! I add extra air above the Harley manual, which I reckon for my bike gives poor advice for 2-up.
