Tread depth and wet braking

Most drivers fail this test and never find out.

California requires 4/32" on your front tires, twice the limit on the rears. The penny test measures the wrong number. Drag the slider.

Water has to leave through those grooves. Shallower grooves move less of it.

195 ft to stop from 70 mph on a wet road
The same distance a new tire needs. This is as good as it gets.

Braking figures are from published wet braking testing of a BMW 325i stopping from 70 mph on wet pavement: 195.2 ft on new tires, 290 ft at 4/32", 378.8 ft at 2/32". Depths between those three measured points are interpolated. Your own car, tires and the road surface will differ. Legal minimums are set by California Vehicle Code 27465(b), which requires 4/32" in the major grooves of steering tires and 2/32" on the others.

Your tire light is not a pressure gauge.

It is only required to warn you at 25% below placard. Everything above that line is invisible, and a Sacramento winter puts you there without a single leak.

    Tire pressure falls about 2% for every 10°F drop in air temperature, roughly 1 psi on a typical passenger tire. The 25% warning threshold is set by the federal tire pressure monitoring standard, FMVSS No. 138, phased in through the 2008 model year for vehicles under 10,000 lbs. Fuel economy figures are from fueleconomy.gov. Temperatures are National Weather Service Sacramento normals. NHTSA recommends checking pressure monthly and before long trips.

    What happens in the bay.

    All of it on Watt Ave, with one exception we would rather name up front.

    Smog checks, 2000 and newer

    Most cars are in and out inside twenty minutes. A lit check engine light is an automatic fail, so read the questions below before you drive over. Some restrictions apply.

    Brakes

    The other half of a stopping distance. Pads and rotors done while the wheels are already off.

    TPMS

    The pressure light that never goes off. Sensors diagnosed and repaired rather than reset and handed back.

    Flat repair

    A patch and a plug are not the same repair. You get told which one your tire is getting, and free patches on tires bought here.

    What we do not do here

    Alignment is down the road

    Not in this building. It is done at the sibling shop down Watt Ave, and a new set of tires comes with one free. Better said now than at the counter.

    Sidewall decoder

    Your tires have an expiry date printed on them.

    Rubber ages whether you drive on it or not. The build date is stamped on the sidewall in four digits.

    The long code on the sidewall. Width, profile, rim size, then how much weight and speed it is rated for.

    Find "DOT" on the sidewall and read the last four digits. Week, then year. It is often only stamped on one side of the tire.

    Type a size code to break it apart.

    Questions people actually call and ask.

    Do I need an appointment?

    Walk ins are fine. Calling first still gets you out quicker, especially after five when the after work rush lands.

    How much is a smog check?

    $49.99. The California average is $74.22 including the state certificate fee.

    How long does a smog check take?

    Customers regularly report being in and out inside 15 to 30 minutes when there is no queue.

    Which vehicles can you smog?

    2000 and newer, with some restrictions. Call before driving over if yours is diesel or older than that.

    My check engine light is on. Can you still smog it?

    We can test it, but it will fail. A lit check engine light is an automatic failure in California no matter how clean the car runs. Get the fault fixed first, then come in.

    I just had the battery changed. Can I smog it now?

    Not yet. Disconnecting the battery or clearing a code wipes the car's own self tests, and it reports Not Ready, which is a rejection rather than a pass. Drive it about 200 miles first.

    Do you do alignments?

    Not in this building. They are done at the sibling shop down Watt Ave, and a new set of tires from us includes one.

    Can you patch my tire instead of replacing it?

    If the puncture is in the repairable area, yes, and we will tell you whether you are getting a patch or a plug before we do it. Patches are free on tires bought here.

    Are you open Sundays?

    Yes. Sunday 10 to 6, and Monday through Saturday 10 to 7.

    Where exactly are you?
