Tread depth is only a third of the story. Answer five questions about your tread, your DOT date, and the way your tires are wearing, and we'll score all four fronts — plus tell you exactly what to do about it. No email required to see your results.

What are we looking at?

It's molded into the sidewall. Skip it if you can't find it — Burt can figure it out later.

The penny test

Lincoln goes in head first. If the top of his head is showing, you're at or below 2/32nds — legally worn out and dangerous in rain.

The DOT date

The last four digits after "DOT" are the build week and year. Trailer and tractor tires usually age out around five years, long before the tread runs out.

The wear pattern

Center wear means over-inflation, edge wear means under-inflation, cupping means worn shocks, and feathering means the toe is out.
