Review on Outus Color Tread Depth Gauge by Greg Mack

Every consumer should have this product. I took my car to the shop for regular service. The garage told me to change the tires because they are going bald. I only bought tires 18 months ago and really didn't want to spend the money. I bought this tire gauge so I can check the tires myself. After checking each tire at least twice, the gauge consistently showed that my tires were fine. I took the car to a tire shop to have it checked again and they came to the same conclusion as me. Save money. spend $5. YOU need to know when to change tires. Do not rely on the honest opinion of a workshop mechanic.
