What tire pressure is recommended for bike -2009 G5 - with sidecar attached?  Thanks, Al

30 rear, 25 front, 20 side.

In my experience with many different types of hacks (Urals, Yamaha 650/Velorex, old '75 Goldwing/Velorex, HD Nightster/Cozy) - this is a general rule for me:
Max (or near) pressure on the tires - all three.
And that is based on the manufacturer's max pressure on the sidewall.
   
The sidecar is a load on the bike - and as with any large load, to increase tire pressure is a good thing.
 
And that can be very different - my Cozy pressure is 33 psi - with the Metzler - but *not* so with the stock Indian tire that came with it - and now serves as the spare. (see http://mysite.verizon.net/respud62/id10.html)

Well, it has to be mentioned that bike and riders differ as well as the toe and lean of the rig and tire type.  All affect the ride of the hack.   I have found the above pressures to work on my rig in that the machine turns well and tracks properly down the road with those pressures.

I usually keep the rear pretty hard as it is that tire that scrubs the most in turns etc.   I also found the car to be too bouncy and unpleasant at 30 lbs.

Increased tire pressure to 30 front/rear, and 25 sidecar.  Rode better with less wobble prior to installation of steering damper.
