GODESON Tire Tread Depth Gauge,Two-Sided Smart Color Coded Tire Tread Depth Measurement Tool, Tire Wear Gauge in 32nds(Pack of 2)

TEL que décrit et facile d’utilisation

All my life I've used the penny method ("if you can't see the top of Abe's head, you need new tires"). And it worked just fine. Only problem was, on rear tires where you can't crank the wheels to display the entire tread, it was sometimes hard to get accurate readings on the INSIDE edge. Also, it only told you if your tires were OK, not how much tread you had left.So I decided to get a gauge. I found many. Some were pricey...I don't need a gauge THAT badly. These Godeson gauges were very inexpensive, and the problems described in the 1- and 2-star ratings seemed minor. Besides, I thought it would be nice to have two -- one in my shop, one in my tool-box...I decided to give them a try.They arrived today. I got the ones showing both MM and 32nds of an inch. They are much better than I expected. As others have noted, the calibration was just a bit off. That is, with the gauge pressed down on a hard, flat surface, they both read a fraction above zero, both by about 1/64". To get them to read zero, I had to grind a bit off the ends of the blades on a diamond sharpening stone -- I had to be careful not to grind off too much.Once the zero settings were achieved (three minutes to do both), I tested their readings, using a good caliper, for various depths from an eighth of an inch up to about half an inch. All readings matched the calipers within a couple thousandths of an inch.OK, I'm a perfectionist. Please understand, I didn't have to do any modification to these gauges: RIGHT OUT OF THE PACKAGE, they would have given me readings accurate to 1/64th of an inch. Who really needs better than that?As to their ability to hold a reading, they both have some sort of damping in the barrel to keep the blade held in place. I have no way of knowing if this will be true...they could loosen up in time. If they do, I'll find a way to tighten them up, shouldn't be rocket surgery.And if needed, I can buy two more for about the price of a caramel frappuccino.
