I want to report on the nitrogen tire filling service done for nada by Middletown Nissan at the car show. For me it exceeded expectations. I was told it would make my low aspect ratio tires ride better. I really think it did do that. Even my wife noticed that potholes and manhole covers seem less jarring. Anybody else that had it done have anything to report?

Psychological effect.

Physically (PHYSICS) you shouldn't notice any difference until your tire temps are very high for long periods of time (Think, Cart, Nascar, Endurance, SCCA Run Offs)

The best determination on a street car or light track use car, should be the pressure readings over long periods of time. (Months/Seasons as opposed to weeks.)

Ok I have to admit, I snuck around the whole state and filled all the potholes and ground the manhole covers smooth....Ah you got me...lol
