Why so low? They recommend 2.7 PSI. That's hard to read accurately when 1/2 psi difference makes it pull. The tire itself says 30 PSI MAX! The tires had 10 psi and it rides OK and steers good. We dropped to 4 PSI and the tires are louder even on gravel and it's harder to turn the handlebars. Some run their tires nearly flat. Does it really help traction? Quad is Honda Four Trax rancher 350.
