Use a tread depth gauge, if you have one handy, to see if your tire tread is between 10/32nds of an inch and 2/32nds of an inch. If you don’t have a tread depth gauge, insert a penny with Lincoln’s head down into your tire’s grooves — if you can see the top of Lincoln’s head, then your tires are bald and you should seek car service immediately at our San Diego service center.

Explaining Safety and Your Tire Tread

Typically, a new tire on your car comes with 10/32nds of an inch of tread — although this varies between used cars. We validate the tires on every used car that comes into our San Diego used car center, but you should also be checking car tire tread depth as part of your used car checklist.

Once the tread gets to 2/32nds of an inch or less, your tire is considered “bald.” A bald tire is much more likely to spring a leak than a healthy tire, and driving on one or more bald tires is hazardous to your safety. If you are unsure if you need new tires, contact our service department.
