Cold tire pressure question
Recently had a new tire put on the rear. I noticed a very slight bounce in the ride yesterday, so this morning I checked pressure front and rear. Front was at 35, rear was at 36. Seems low to me....I was running 40/40 on my Heritage.
What is the best on a Ultra Classic? Still 40/40? I think this is where my little bounce is coming from.
Thanks!

depends on year and model...let the owners manual be your guide
on my 09 I run 38/40 cold...which for us is 80ş+
We have a great variety in elevation in AZ, when I run up to Flagstaff, I will often top up the tires again.
I should switch to nitrogen...larger molecules won't migrate out as easily and less subject to expansion/contraction

It also depends on what brand tyres you have now. If you changed to another brand, the correct pressures may be different. In any event I learned long ago that adding a couple of psi seems to improve ride and handling, also reduce front tyre wear from braking.

IF you are not running stock tires """DON'T" JUST GO BUY WHAT THE "MANUAL " SAYS!
Different Tires/DIFFRENT BRANDS often run different max pressure .
Look at the sidewall and run it at the max pressure listed .
Your tires will last longer and your bike will handle better = SAFER !
My personal opinion is I run one or two pounds over listed max pressure for longer life .
RESULTS MY VARY !
Oh ya , spend a few extra buck$ for a quality air gage .
Throw the $1.99 one away.
Check your presure frequently .
PLEASE NO WINING FROM THE PRINCES AND THE PEA GUYS ABOUT FEELING EVERY CRACK IN THE ROAD WITH PROPERLY INFLATED TIRES
