A mechanic told me that the correct rear pressure for the GL1500SE with a sidecar as measured on its center stand, should be 4.35. With all three on the ground, the pressure gauge reads 5.4. Can this be correct?
I've only had the hack for four months and it is difficult to discern the difference if I adjust the pressure. I had it at 3.3 as the manual suggests (without sidecar) and now more or less 5.
What should it be and how can I measure it with all wheels on the ground?
Can anyone please advise?
Thanks!
With the Harleys (which are factory sidecar recommended) the increase in rear tire pressure is only 2PSI which is the same as for riding two up, 34 PSI to 36PSI.
A GL1500 would be about the same.

Hello
What are the pressures relating to if it bar they are to high.
Barry
14,5 PSI = 1 bar.
On my rig I ride 28-36PSI = 1.9-2,5bar depending on which tire => the highest load with the worst tire ever needed 46PSI = 3.2 bar 0 => lowest presure in bad mud were 12PSI = 0,8 bar.
As things depend on many aspects like tire type,bike and s/c weight, load, tire style...I genaraly don't trust the manuals recomendations.
Cheap bike tires with only few layers feel horrible and need more pressure, while car tires need less presure then they are used to for car use.
My way to proove things out are test rides where I take an inflator or mini compressor with me.
I have somebody riding behind me and make a real monkey show on an empty parking lot.
The observer and mostly your own (four letter sensor) too can tell very fast when the tire presure is wrong.
Too high presure you rubb and loose traction easily.
Too low presure the tire tries to flip off the rim.
Car tires should have their thread flat on the ground and not bow up (too high presure), nor bulk in (too low presure)
Allways use your normal riding load for the test ride.
Enjoy
