I'm a new S2000 owner more attentive to details, now, than with my old pickup truck. I have 3 tire pressure gauges, no 2 of which are within 2 psi of each other when measuring the same tire. They are the $3 - $5 variety found at auto stores like Pep Boys, AutoZone, etc.

What brand/model gauges are being used to maintain the precision tire pressures for this high performance fun machine? What percent accuracy (or tolerance) is expected for tire inflation on these cars? +/- 1% or 2%? Maybe some of you, or particularly, those who race can tell us what you use to set your tire pressures.

Thanks, all. The input on these forums on other questions has been much appreciated.

 

Check out Longacre's gauges. Here's a link, you might be able to find it cheaper elsewhere.

Quite a few of the Autox guys here use the ones from http://www.racerpartswholesale.com/. Just click "complete index" then "tire gauge".

Cheers,
