Greetings, Looking for some feed back on a what is out there for accurate tire gages. I have a roadcrafter digital for $19.00 and seemed to work for about a year, but now it takes numerous attempts to get a readiing and I am not sure how accurate it is. I compared it to a circular dial type gage and it was off by 2psi. Is there a way to check the calibration or do you use at least three gages and take the avreage? I am open to suggestions on type and brand because I use it often and want accuracy and reliability. Thanks.
