Lower tire pressure for softer ride?

What pressure do you run your tires and hows the tire life? Anybody run there tire pressure lower to get a softer, less harsh ride on a Road Glide Custom / special/ standard? I've only had my '18 standard a few weeks but the ride is pretty harsh. When I picked it up and rode it home it rode better than the Road King I traded in. I checked the tire pressure in both tires before the next ride and it was 34 front 36 rear. I added air to make it 38 front 40 rear. Same as I've set it on all my bikes. I get good tire life with minimal cupping. Since adding air the ride has become harsh both front and back. tried adjusting the rear shock with very little results. Any ideas besides changing out the shock and suspension? Is it the low profile tires? or wheel size causing this or a combination of all the above?

Not sure running lower tire pressure in low profile tire is a good idea. I believe the low pro tire take away from ride while may be adding to handling performance. I know my 08 was a smoother ride than my 19 but the 19 handles corners better especially at higher speeds. Changed out rear shocks with Ohlins ride is much better than stock

The problems isn't the tire pressure, its the suspension. Believe me, just search the forums here and on HDForums and you will find a million people saying the same thing. Start by changing the rear shocks and you will notice a HUGE difference in the ride. Then change the front and AMAZINGLY you will be riding on clouds....

Pick your brand Ohlins, Super Shocks, Progressive, Legends, etc... there are a million out there and they are all better than stock. All of them have their advantages. Hell you can even spend more coin if you want and throw on an air ride!!!! That will put you in heaven on the road for sure, believe me I know I experienced this first hand riding a Brothers bike not too long ago.

Do your research, pick your suspension upgrade, make the change, enjoy the ride........

I changed my rear shocks within 60 miles of owning my special. Whatever shock you choose, make sure it has a longer stroke than these 12 inch Harley shocks.

I went with Ohlins from @Smarty because the Ohlins guys were at Shark Week Cherokee and I learned a lot talking with them.

Plus, I like telling my sport bike friends that I have Ohlins on my Harley.

I used to use my tire as a shock. Had too. 1948 Panhead. Stock rigid frame. but now days. We have many options. As listed above. I have progressive monotubes up front. and I'm ok with the stock 12" rears. For now.

Lowering tire pressure will affect safety and tire wear. Too low and the tire can overheat and blow. It will cause cupping, and have an adverse affect on handing.
The standard shocks suck big time. I about went over the bars (on an on ramp I've ridden over 100 times on other bikes) with my 19 RG. I just rode over the same onramp with my new Legends and it was drama free.
If you buy new shocks make sure you buy them from someone you trust to set them up properly. Set up is as important as the quality of the shock. Little things like setting the sag make a massive difference.

I run whatever is recommended on the sidewall. Ohlins made all the difference.

The owners manual is the best place to find out what pressure you should run. The same tires can be used on different weight bikes (with different loads) and the manufacturers don't know the specific bike you are putting it on.

Lower pressure is a super bad idea. Low pressure = heat. Heat = blowouts.

You'd be surprised at how many travelers die in this area from blowouts or tire separations.

The owners manual says 36 front 40 rear. So I'll drop the front a couple of pounds. I agree the bike needs shocks.
I rode 12" air shocks with upgraded 10 wt shock oil in it for years on my 2011 RGU till I got ride of it.
I've got some 12" and 13" air shocks I may throw on there to get me thru this riding season.
