Go with the recommendations in the Harley manual. Adjust for your load (weight of you, your rider and baggage -- don"t be lazy about adjusting for different loads).
The number on the sidewall is MAX pressure the tire is rated for--the "do not exceed' pressure. That spec is determined by the tire manufacturer. However, when the tire leaves the tire factory, they don't know what motorcycle it's going to end up on. Therefore, the motorcycle manufacturer's spec trumps the number on the tire sidewall. BTW, the same principle applies to tires for cages, too.
Check pressures often--you only have 2 contact patches and unlike 4-wheelers, you lean on them
Good question--lots of confusion out there about that.

If you give up drinking, you don't live longer. It just seems longer.

HD's manual is good for the stock tire. Other aftermarket ( Avon etc.) use the mfg's recommendations.

HD doesn't make it easy to check tire pressure on the Ultras. I know that's no excuse for not checking tire pressure, but it sure is a pain.

No matter how you slice it thats still Dino air, as said earlier you may want to consider syn air.. better stuff but it is noisy......

28 spoke wheI agree that its a bitch to check the air on the 28 spoke wheels....I found that you can bend the stem over a little bit and your guage will go on a lot better...I hate the 28 spoke wheels...

Same here. I switched to methane instead. It's free too 'cause I get it by farting into the air intake of my compressor.
