    Amazon: Moonet Universal Spare Tire Cover Black (14 inch) $12.95
    Make sure to order 14 inch, even though the tire is 15 in, 14 inch size cover is the perfect fit.

    In case you have ad block on and can't see the link above.

    The reason I don't is that my car didn't come with one, and I've never had a sudden flat on well-maintained tires. I know it's possible, but it seems very unlikely to me when you properly maintain your tires.

    I've had many punctures, but all of them caused slow leaks, not a sudden flat. I've had flats caused by poorly maintained tires (maintained by others) but never on a properly maintained one.

    Agreed. Mine didn’t either, I just sleep better when away from home
    We’ve made the trip to Florida 15 times now without issue. That’s why I drive a newer Toyota and carry a spare, along with emergency kit

    And that could be just a partial lift, nothing dramatic: you just want to get the bulk of the weight off.

    Toyota would love to sell you a new tire, tpms, gunk/compressor when you pull into the dealer ;)

    That makes no sense to me. Like they somehow avoid screws/bolts/nails? No, don't get it, lol.

    My most recent car flats were from a large bolt, and a plumber's pipe hanger. My eyesight just isn't good enough to spot them far enough ahead to dodge them. Or even to see them at all before impact and impalement.

    A bicyclist I helped yesterday (during a cycling event on our new SR99 Tunnel) had his tire ripped by a large drill bit, somehow broken / dropped / not swept up by construction crews. Fortunately I brought along some of my old bike tires to give away as emergency replacements. The club provides spare tubes.

    As I said, I've had punctures (from screws/bolts/nails) and they have resulted in slow leaks, not fast flats.

    I've had numerous slow ones too. But the ones I mentioned above were fast.

    That's been my experience, but one time, the offending bolt popped out for a fast flat before I got home.

    Recently I was on the road in Prime and heard clicking sound from tire. I stopped and could see tire low, and saw screw in tire. I pulled off the road, jacked car up with tools provided and removed tire. Then plugged tire with kit I had bought and pumped tire up with hand pump I carry. Put tire back on car and drove to tire store for permanent tire fix which was without charge. I don’t carry the goop and compressor supplied with car. I have since replaced the hand pump with a 2” X 2” X 9” lithium battery tire pump which fits in compartment designed for plug in cord.

    With our Prius I've had one of each.

    I still don't understand how this got passed the safety regulators. If the 12V power fails, you have no emergency brake. The old fashioned one with a cable from the parking brake pedal to the rear brakes is the epitome of simple reliability. Kind of like the design of a single-engine Cessna airplane: carbureted fuel supply, dynamo for ignition, propeller directly connected to drive shaft, cables from controls to control surfaces.

    Is the parking brake regulated in this manner?

    Power assist failure of the main service brake is regulated. It if fails, the old fashioned manual braking path via the hydraulics still works, albeit requiring far more pedal force.

    And how many have died because of carburetor icing, failing to manually control mixture properly, and broken, snagged, or off-the-sheaves control cables?

    Putting up small GA aircraft as examples of reliability is very naive. The fact that most of them run on 50's technology is one of the reasons their accident rate is so high (but not the only reason).

    Would it make that much difference? Air is a fluid, so pressure is equal throughout the tire and compressor while connected to the tire.

    Say 1,000 lbs runs on each tire. A torus (because that's what I can find in one minute) the size of a 185/65 R15 tire would have about 915 square inches of surface area, or close to 1 psi to lift the car.

    Um...the patch of tire touching the ground is the only part lifting the car, and it's more like 100 square inches when flat.

    That's not how air pressure (and hydraulics btw) work. If the pressure is x at one point, it's x at every point. The load is borne equally everywhere. That's why air-powered tools and hydraulic machines are so powerful: you can apply 10 lbs of pressure to a 1 square-inch piston and that applies 1,000 lbs of force to a 100 square-inch piston on the other end.
