Accurate Tire Gauge??

I would like to keep my truck and RV tires properly inflated but I don't know how to do this. I have 4 gauges that I thought were good, ranging in price from $12 to $40. Maybe this is the cheapo range I do not know. All I know is that not one of the gauges read the same. One of them is as much as 15#'s different. Can anyone tell me where to buy a tire gauge that I can rely on?

Accurate Tire Gauge??

I think all guages have an adequate 'theoretical accuracy'. What you are seeing may be variances in 'practical accuracy', which depends on how easy the guage is to use. I'd look for one with an easy to read guage, which holds the reading until you manually release it. This will eliminate some of the more common ways for variance to creep into your readings.

I got a nice one from Camping World for $20 or so on sale, but frankly, I've had such trouble finding places to 'air up' that I think the hot setup would be a rechargeable battery powered compressor with a built in guage.
