Tire Tread Depth Calculator
Measure your tire tread depth, understand wear patterns, and determine when to replace tires for optimal safety and performance.
Step 1: Tire Details
Understanding Tread Depth
Tread depth is measured in 32nds of an inch. New tires typically have 10/32″ to 11/32″ tread. Most states require replacement at 2/32″ for safety.
Step 2: Tread Measurements
How to Measure Tread Depth
Use a tread depth gauge or the penny test. Insert a penny into the tread with Lincoln’s head upside down. If you can see all of Lincoln’s head, your tread depth is less than 2/32″ and tires should be replaced.

Legal Minimum: 2/32″ in most states
For optimal wet weather performance, consider replacing tires at 4/32″. Winter tires should be replaced at 5/32″ for maximum snow traction.
