New to HD... i looked all over my HD SG user manual and it dont say anything to what the front and rear tire pressure should be. the tires are stock&nbsp\\;.
2008 SG with ABS.
&nbsp\\;

 

Look on the sidewall of the tires, should be about 42 psi cold.

 

There should a sticker on the frame with the info.

 

My Fat Boy takes 36 psi front and rear, when riding solo\\; 36 front and 40 rear when riding 2 up.
I am fairly sure all the big twins with the fat front tire take the same air pressures.

It's listed in the Specifications tables (Table 11 in my 2006 Dyna manual).&nbsp\\; I keep my Street Bob around 35 front and 40 rear, although&nbsp\\;the manual calls for&nbsp\\;30 front and 38 rear (solo rider).
