Have added small amounts of air to my rear tire all year, dealer can’t find a leak anyone have this issue?

I add about a pound, maybe two, every two weeks or so. Temperature has a lot to do with your air pressure reading too.

How much pressure loss over how much time? Pressure also changes with temperature, approximately 1 psi per 10 degrees Fahrenheit, so you also need to factor in temperature when making comparisons from one day to the next.

I typically add air every month, 1-2 psig. If you don't have a nail hole in the tire and are losing more than this, you have to either look at the valve or bead. It's not uncommon to get a bit of corrosion under the bead. It will be very obvious if this is the issue when the tire is removed, but occasionally a weeping leak can be detected with soapy water.

I had the front tire on my 15 limited leak down and had to add the day I rode it home and add air every couple days. Sometimes it would be down by 15 lbs if I didn't add by the 3rd day.
Dealer didn't find anything, and it still had the soap on the bead that I used, so they put on a new tire.
2 days later same problem.
Local dealer put a new tire and valve assy on.
1 month later a new rim.
It has held air now for over a year.
Maybe a simular thing on yours.

Probably more common than most would think, especially with aluminum wheels made by the lowest bidder. Porosity issues with aluminum castings have caused leaks with everything from wheels to engine parts over the years. Considering the price Harley charges for their CVO wheels, anyone having significant tire pressure loss even after replacing the tire and valve should be aware of this possibility and insist they test and replace the wheel before the warranty expires.

I would inflate the tire to 60-70lbs and spray soapy water all over the wheel and start carefully looking for the bubbles, I would start with the tread, then concentrate on the bead then the wheel, Jerry is right with a possible porosity in the wheel, I have seen that on GM and BMW wheels along with a couple of cylinder heads that caused a very hard to find oil leak.
