Michelin Digital Tire Gauge: 0.1 -0.3
Slime Brass Tire Gauge with Bleeder Valve: 0.5 - 1.0
Cheapo Pen Version: 1.0-2.0
Moral of the Story: Considering how import tire pressure is in a car, it's worth spending $20 on a good one. (Especially for guys who are as neuotic as me  ) |
Gatoman,
OK, we're neurotic, but there's nothing the likes of us can do about it; if we weren't worrying about tyre pressures, there'd be something else to fret about.
Case in point being the price difference between the UK and the US - are you saying that you bought that Michelin gauge for $20? The cheapest I can find it here is £25 - that's $39, and I thought I was going to have a good day
!!!
As a matter of interest, what did you use to determine the gauge accuracy?
