What is the correct tire pressure for a 2009 Fatboy?

Answer 1

Take the total gross vehicle weight, passenger weight and all the gear. Divide that weight by the weight of the load capacity of both front and rear tires. Then multiply that by the max load psi as printed on the tires sidewall also.

For example:

Vehicle weight = 750

Passengers = 350 (with all gear and ready to ride)

Total gross weight 1,100 lbs.

Sidewall rating of both tires added together 1600 @ 42 psi.

1,100 / 1600 = .688 * 42 = 29 psi

So 29 psi would be the starting point of this example. You should also adjust the shocks according to your load as well.

That equals your current load pressure for your motorcycle. Adjust accordingly to your passenger weight change.
