Tire Tread Depth Gauge
The best way to monitor tread wear is with a tread depth gauge.
The gauge can detect a wear pattern sooner than by just
Looking at the tread. Unusual wear patterns in the tire can
Be caused by incorrect air pressure, loose or worn steering
Parts, driving patterns, load conditions, etc. When a wear
Pattern is detected using the tread depth gauge, you can
Then search for the cause before excessive tread
Wear occurs or the tire is ruined.
This gauge reads in 32NDS and millimeters.
The higher the number the more tread depth on the tire, 2/32 and below is considered illegal in most states to drive on.
