So after reading this I watched my tire pressure on a 270 mile ride today. I have the original made in the USA AE's. I inflate my tires to 36 and 40 psi. After warming up my front tire was at 40 and hit 41 a couple of times. The rear tire was 45 and hit 46 a couple of time. Temps ranged from 58 to 77 degrees. Seems to be a similar psi difference as the new version. I didn't notice a difference in ride as it always rides hard. Switching out to Ohlins front and rear this winter.

 

I have the same tires (though on a softail Heritage) and switched to Ohlins front and rear. What a difference - rides like a dream compared to the cheap, harsh, jittery stock suspension. I can't believe an expensive bike like Harley comes with a cheap suspension. Anyway, this is a must-have mod IMHO, you'll love it.

 

On my Dyna FXDI35 with 1st Gen. AE's I'm going by what they suggested, 40 rear and 30 front, I live in SW Fl. and the bike and my 160 lbs person handles great wet or in the rainy season down pour great of course in a down pour I do back it down some but with confidence. I'll be looking for new rubber right after the winter so looking at the AE 2's I'm considering different. Not really confident on the tread patterns.

 

If you use the recommended HD brand air and change it to the winter air blend for cold weather and summer blend in warm temps those symptoms will be minimized. 😁
