If you run tire pressures recommended in a 1970's manual you will be severely under pressured and could be dangerous. Old school rule of thumb is look at the Max PSI on tire and subtract 10% as a good starting point.
I just had an issue with my Shinko tires on the '70. Manual pressure was in the low 20's, I called Shinko they said go with the max pressure listed on the sidewall, 41 PSI. They offered that some people take out a pound or two for comfort, so I am now running about 38 PSI.

Moral of my story, call your tire manufacturer.

I called a guy name Dave at Dunlop tires and he said 36 front and 36 rear. Which equals to minus 10% of maximum tire pressure coincidentally. He also said that you shouldn't go off the old school manuals only because tire technology has changed dramatically and going off the old recommendation isn't a good idea with new tires from this era
I was looking in my original owners manual for my 1979 shovelhead flh classic and the recomendere PSI at maximum is 32 PSI; however, I looked on my tire and it said 40 PSI max recommend. Which tire pressure should I follow? I had my tires at 38.5 PSI and rode nice, now I have 40.5 PSI and it feels "a little tippy" so I'm back to 38.5 PSI. The tire size is original to the bike
I just sold my 1980-83 factory service manual,and for the FL it showed 36 front 40 rear. I had it written on the front cover.
My 81 FLT is run at 38 front , 40 rear. Anything less and the bike wants to wallow around. You will know if it's too low, bike won't handle worth a crap.
bass, what tires you running on your flt? curious since I have an 80 flt? mine has the "old school" looking tires on it but I'd like to change them to a modern tire.

That's it exactly.
Every bagger I have owned.... shovels, evos, twin cams..... will wallow around if the tire pressure is too low or mismatched from front to back. I run 34/34 in my 1982 FLHC and 38/40 in my evo bagger. It's amazing how much difference it makes.
