So read your sidewallls.....and remember that is M A X PSI pressure

I suppose if you weigh 400+ lbs running 36 psi might be okay, as long as you don't care about tire life.

It's funny people think they need so much psi in a tire yet can't figure out why they only get 5,6, or 7k out of it, lol.

Stock Dunlops, run 36lb both front and rear all the time.. If I run less it doesn't handle as well.

I run my rear at about 40 at all times and I like it, but i'm use to it. Now when my my front was down to about 32 the one day that sucked! Bar slap like crazy.

Maybe that's why I don't get good mileage out of rear tires,I follow what Harley says to put in.

Hard tires spin good and soft tires grip the road. To much air turn your tire hard with less grip. 40 pounds of air or more will spin my tires. And with 9 pounds of air will do Wheelie most all day. Don't run the roads with that low air pressure as your tires may run off.

I run 40 in the rear & 38 in the front weather I am 1 or 2up.

Same here. After my last service I checked my front tire pressure, someone had bumped the pressure up to 44 lbs! I took it down to 38 and the handling was way better. 40 lbs in the rear seems to work pretty good too.

You run what you want, and I'll run what I want.
It's been my experience that running to low will results in cupping.

My owner's manual with the stock Dunlops says, Solo front, 30 PSI 2 up, 30 PSI. Solo rear, 36 PSI, 2 up, 40 PSI.

I changed my front to a 21" Metzler. 38 PSI per Metzler's web site.
