A tire tread depth guage can be purchased at your local auto parts store for about $6.00. TiresShaved.com recommends Milton tire tread depth guages because of their accuracy.

To check the depth of the 3 existing tires put the guage in the center most groove of the each tire and send us the measurement of the tire with the least amount of tread left on it.

We will then shave the new tire approx. 1/64 more than the measurement you send us. This way you have a little " wiggle" room so to say in case you were a little inaccurate when checking your tread depths.
