As these grooves wear down over time and miles, the tire's capacity to disperse water decreases. Conversely, worn tires grip the road primarily through the small edges of the tread blocks, which are insufficient to handle water volume, leading to a sudden loss of control.
Understanding Hydroplaning Risk Through Tire Tread Depth
This guide provides a detailed look at how to assess your tire tread, the legal and safety thresholds for replacement, and the best practices to ensure your tires perform optimally for as long as possible. This measurement is typically taken from the top of the tread wear indicators, which are small bars located at the bottom of the tire's grooves.
In rainy or snowy conditions, this can lead to a dangerous buildup of water between the tire and the road surface, a phenomenon called hydroplaning. For optimal safety, especially in wet climates, replacing tires when the tread reaches 4/32 of an inch is highly recommended.

Insert the penny into the tire's groove with Lincoln's head facing one of the tread blocks. To measure, insert the gauge into the main grooves around the tire, ensuring the gauge's probe touches the bottom of the groove.
