Review on 📏 Tire Tread Depth Gauge | Accurate Measurement Tools by PROND (Green Type - 2PCS) by Brent Henderson

Instruments are very difficult to read (perhaps partly those old eyes). One of them has enough friction on the barrel so that the reading does not change when removed from the tire, the other is so weak that there is no way to remove it from the tire and get an accurate reading. I thought I read 5/32 on all tires but the tire shop showed 3/32 on the rear and 4/32 on the front.
