I ride a 2003 FLHPI everyday, I just rolled 100k miles and need new tires. I am looking for a good set, I generally use the standard D402 because that is the easiest to get and when I get new tires it is because I need them now. I have had Metzelers before on my Sporty and really liked them. When j tried to translate the "MT908-16" to a metric reading, it does not work. An MT90 would be a 130/90 but my specs add an "8" at the end which messes me all up. I know that the standard tire for the police model is a runflat, is that what the "8" is saying? It is supposed to be a 130/90-16 runflat? If anyone has a better tire suggestion too that would rock! Thanks everyone.
Peace.
Peace.
I think it should be "MT90B16"

No, it is supposed to be 8. I have actually found some one who knows the answer. The 8 does, in fact, stand for runflat. It is a police tire and that is what the specs on the bike call for, though any MT90-16 would work. Including a "B."
As fire tire pressure. Set your front and rear to 40#s. The ride will be more comfortable and you will get longer life out of your tires. If you are ever in doubt, go by the mad PSI on the side wall, it says it very clear. Always go OVER the max not below. You will not hurt the tires by going over but you will over Heat your tires running just 5PSI under.

Here's a page from the 2008 FLT Police Model Service Supplement:
TIRES 2.3
GENERAL
The rear tire on FL police model motorcycles is fit for solo riding
only. If converted to a two-up bike, that is, configured for passenger
use (with luggage), then the rear tire needs to be
changed to one with a higher weight rating. Since it has long
been Harley-Davidson policy not to mix different types of tires
on the same vehicle, we strongly recommend that both front
and rear tires be replaced. In order to alert the customer to this
safety issue, the following warning appears on a label fitted to
the rear fender approximately 1/4 inch (6.4 mm) behind the
domestic seat mounting hole.
This vehicle has tires with weight ratings for one person
operation. If this vehicle is modified to carry two people,
the tires must be changed. See a Harley-Davidson dealer
for proper replacement tires. Using improper tires can
cause tire failure which could result in death or serious
injury. (00096a)
NOTE
Use the tires recommended for civilian/pleasure vehicles of
the same year and model family.
Harley-Davidson front and rear tires are not the same.
Interchanging front and rear tires can cause tire failure,
which could result in death or serious injury. (00026a)
Tire size, manufacturer's description and inflation pressure are
listed below.
NOTE
ABS motorcycles must always use tires and wheels that are
the same as the original equipment. The ABS monitors the
rotational speed of the wheels through individual wheel speed
sensors. Changing to different diameter wheels or different
size tires can alter the rotational speed. This can upset the
calibration of the ABS and have an adverse effect on its ability
to detect and prevent lockups. Tire inflation pressure that is
significantly low also can have an adverse effect.

TIRE PRESSURE

TIRE LOCATION SIZE MANUFACTURER'S DESIGNATION
Front MT90B 16 72H Dunlop D402F PT 36 psi (248 kPa)
Rear MT90B 16 72H Dunlop D402 PT 36-40 psi (248-276 kPa)
All 2008 vehicles use only Dunlop Harley-Davidson tires.

I also have the 1994 FLHTP Service Manual Supplement for Police Models that lists the following information for tires:
FLHTP
Front MT90B16 Dunlop D402F 36 PSI
Rear MT90B16 Dunlop D402 36 PSI
I did notice that the 2008 manual has a "PT" designation after the Dunlop D402.
I wonder if that designates it as a "Police Tire"?
Here's a link to a Dunlop Technical Tyre Release for "PT" tires dated August 2011:

I have a 2003 without ABS so that is not an issue really. As for the MT908-16, the 8 is a runflat designation, sometimes labeled PT for "police tire." The weight rating is the same when the tire is filled properly, the runflat feature is designed only for a single rider, so when you do have a flat the tire is rated for one person only. Though harley has changed their policy to no longer sell PT to civilians. They are for use on police vehicles only.

2016 Heritage Softail Classic
I've got a 2016 Heritage Softail Classic, Screaming Eagle 103 (upgrade), American Freedom (True Duel) fishtails. running the Dunlop 402's. Now have about 13,000 miles, and the center of the rear tire is worn out, while the sides look almost new. Owners manual states 40 psi in rear. I ride solo only, and weigh in about 170. Thinking of dropping pressure down to about 36 psi to get better wear. Suggestions / comments ?

Hey brother, I recomend you do not go with lower tire pressure. One of the reasons we do not use standard car tires is because of the sidewalls. They do not have the support to keep the tires from rolling; they are designed to have support on the outside not the inside because the tires on the opposite side will provide support.
If if you have ever had a flat tire you understand the deminished control with low pressure tires.
As someone who has ridden daily for monetary necessity, I understand the pain of replacing many rear tires. Sometimes you have to just bite the bullet, as much as that womps.
