I was looking at my service manual and it stated that 2.2 psi is recomended in the tires. I have a needle air gauge that will read 1psi. My question is that I put in the recomended 2.2 and the tires were hard! My 200s has front suspension, but the aount of air seemed a but much, not havimg rear suspension. Should I get a digital gauge or deflate them to a point that seems apropriate.

Thanks in advance!!!

 

The minimum is 1.7psi and the max is 2.6psi. But the best and most accurate way is to inflate it to a circumference of 75.6 in.
