Recommended psi should be on tire's blackwall.
The correct tire pressure for a Harley Davidson FXD is 30 psi for the front tires. The correct tire pressure for the rear tires is 40 psi.
On a scale of one to ten, I'd say it's a two.
36psi front and rear
Harley-Davidson motorcycle company recommends a tire air pressure of 18 pounds for the street glide model. Substitute tires may require a different air pressure.

Harley Davidson recommends it (Citco I think) but No!!! Just use the correct weight for your motor, time of year and how you ride it!
Perhaps when the word "Harley" is spelled correctly - the answer may be provided.
The tire pressure is dictated by the tire manufacturer. Look in the side walls of the tire or contact the tire manufacture.
35 front 40 rear tire.
10 Psi is all that's required..the Harley engine needs oil Volume..not pressure..the lifters rquire 8-10 psi of oil pressure...Use a Synthetic oil..not the mineral .
As with all cars and motorcycles, that are factory, there is a sticker located somewhere on the bike, usually on the neck or the downtubes, that will tell you correct tire pressure. Front and rear.
