Review on 📏 Godeson 88702 Pack of 2 Smart Color Coded Tire Tread Depth Gauges by James Gregg

. Now you can be sure that your tires are too low. I understand the penny test works and is still valid, but it gives you an accurate reading every time so you know how much tread depth you have left! Don't let a set of tires or an inspection fool you. In Pennsylvania, 2/32 of an inch is the legal limit, and anything below that is illegal. The local dealer tried to sell her new tires and failed the inspection. They're at 4/32, which is double the limit. Next time someone tries to rob you, just take that with you and you can show them you still obey the traffic rules. Also, it can tell you when you need new tires, which is just as important. For $5, that's cheap reassurance.
