Having a flat fixed by a tire or repair shop typically costs $5-$40 for a standard tire and $30-$60 to repair a run flat tire (designed to be safe to drive on even when it is flat).

Swap one of the flat tyres with your spare. Then call the NRMA or the towing company. Tell them you have a flat tyre and that your spare tyre is also flat. More than likely they will suspect what has happened but will not be able to charge you at the collision rate for your tow truck.

Like a damaged valve stem, a leaky tire bead can be to blame if you keep getting flats. Tire bead leaks are also known as bead-seat surface leaks, wheel leaks, or rim leaks. Additionally, damaged, bent, or corroded wheels can also lead to bead-seat surface leaks.

You should never attempt to drive any further than a couple hundred yards on a flat tire, even if it isn’t completely deflated. This may not be enough distance to get you to an auto garage, but you can at least creep along until you’re away from the hazards of the highway.

A tire is liable to go flat overnight if it has been previously punctured during the day by any sharp object such as nails or broken bottles and the tire pressure is gradually lost during the night. When such happens, the reduction of air pressure is faster after it is parked at night.

There are Several Possibilities as to Why Your Tires Lose Air: a hole in the tread, probably from a nail or something sharp in the road. a poor seal where the tire attaches to the wheel, which lets air escape. a loose or improperly functioning tire valve.

A general rule of thumb is to drive no more than 70 miles and no faster than 50 miles per hour before replacing your donut with a new tire.

Expect to pay: $13 to $45 dollars per tire industry-wide, depending on the size of the tire. Mounting (installing tires on to the rims) and balancing (adding weights to make sure the wheel weighs the same all around) varies widely for cars, SUVs, and light trucks, and is highly dependent on the size of the tire.

Sometimes your slow-leak tire might only lose air when you are driving. You might have a pinhole puncture so tiny it is does not even widen enough to let out air until your tire heats when it drives on the road. That temporarily expands the size of the pinhole and also increases the tire air pressure to push out with more force.

When Tires Lose Air, Even With No Visible Punctures. a hole in the sidewall, probably from an encounter with something sharp on the road. a poor seal where the tire attaches to the wheel, which lets air escape. a loose or improperly functioning tire valve.

Age, exposure to contaminants and stress can cause parts of your tire and rim (wheel) to fail. But what do you do if your tire is not visibly damaged? Consider that one of these problems is causing your flat tire: Running over any sharp object can puncture a tire.

Anything that can damage a tire or rim — punctures from a nail, metal fragments, broken glass, a piece of wood, a cracked rim or sidewall rips from hitting potholes or a curb — are considered road-hazard damage. Only your tire technician can determine which of these are repairable.
