Dear Sir.

My Tire is "S1 noble 225 55R 17".

I'm like a hard feeling. So normaly fill up the air is 38 PSI.

How do you use PSI for your car?

Anywhere between 35-40 PSI is acceptable. Depends on the weather in your area.

But you'll find a slight difference in this PSI margin. 40 sometimes feeling too stiff and rugged over bumps, pot holes etc.


I have mine on 38 PSI Nitrogen.

I run 33 PSI on Nitrogen from the friendly folks at Costco who provide free pressure check and tire fill up anytime you stop by Costco if you are a member. I always buy tires for all our cars at Costco.
