I have a 2019 Ryker Rally, but it came with the 900 ACE wheels and tires. I assume the tire pressure for the front tires should be the 900 ACE specs of 25 psi, and not the Rally specs of 20 psi. The tires for the Rally and 900 ACE are the same size, but have a different tread design, and therefore the different psi specs, I assume the tire psi spec have nothing to do with different suspension.
