Correct Air Pressure

[mcdonaldroadcapt]

What do you recommend for tire pressure in rear tires on MotorTrike Trog?

Thanks.

I run 20-21 psi in the rears, and 40 in the front. Air bags 15-20 solo and 25-35 two up loaded. 2007 FLHX M/T

OK, I am in the ball park. I ran 28 lbs for 13,000 miles but after removing wheels for maintenance, noticed tires wearing in the middle of tread. That was the reason for my asking. I also run 40 lbs in the front 21X3.5 Avon tire and get good turning ease and good wear.

Thanks for response.

Here's a little write up I did to help determine the right pressure for you:
Water down a flat paved area(driveway).
Pump the rears up to about 35psi.
Start riding the bike forward/reverse over the wet paved area letting small amounts of air out until you see a full tread width flat tire track left in the wet pavement.
Check the tire pressure in each rear tire.
Repeat this process w/the various way your trike will be loaded and record the pressures for future reference.
That's how I arrived @ 20psi left and 22 right for my normal settings.

I like that method. I always just have to guess when I am getting ready to pull trailer. Now I have a scientific method to inflate tires correctly

Same method goes for any vehicle/trailer you have!
