Our first flat tyre — part 1

Snowy Mountains + Gippsland 2025–26

Soon after leaving Gerringong this morning, we noticed in the Tesla’s screen that the rear passenger side tyre had a lower pressure than the others. We have a pump, but it was packed under the boot floor, under all our luggage.

I pulled into the first service station we passed, asked the attendant where the pump was. They pointed to a box in the store room and said they’re waiting for it to be installed. A few kilometers down the road, we found a connected pump at a second service station. But the round gauge (pictured) wasn’t accurate, showing about 20psi more than correct. Just like a Goldilocks story, the third station was “just right”. We pumped up, using the digital settings, drove on, watching the Tesla screen for any reduction.

During the next 100km, the tyres warmed up and increased pressure. Initially it seemed that the previously low pressure tyre might be fine, but then we saw it very slowly drop. I’m guessing it was taking about six hours to lose 10psi. We just kept driving, keeping an eye on the pressure displayed on screen – it’s such a handy feature.

We’ve driven over 120,000km in EVs, with no previous flat tyres. We have had a cracked windscreen, which is statistically more likely.

I checked the tyre, as best I could, for any protrusions, such as an embedded screw, but found nothing.

We made it all the way to Mallacoota, without needing to pump up the tyre again. We will need to pump it up before we leave in the morning. Tonight, after unpacking the car into our accommodation, I will move our pump out from under the boot floor into the boot side pocket, so it’s easy to use and plug into the 12V socket. But that’s tomorrow’s job.

I’ll post updates on this tyre story, including contacting Tesla, and the eventual remedy. Follow us at Tesla Tripping.

  1. Are you sure that's safe, adding air without knowing the underlying issue?

    1. Kylie Gilroy Fair question. I did what I could to check for protrusions. Since the leak was so slow, I figured the cause wasn’t too bad. But I could be wrong. I was tempted to contact Tesla’s roadside assistance along the South Coast, but figured we could make it back home first.

      1. Tesla Tripping I'm glad it's worked out so far for you.

    2. Kylie Gilroy when you're out in the countryside, you do this and keep monitoring if it seems like a slow leak. I've had three in the last two months. I do have an electric pump in the car as well as a space-saver spare wheel. Used the pump but haven't yet used the spare (Model Y Juniper). I live near Gin Gin QLD.

      1. Scott Howard we've done lots of road trips from
        Mackay to Wollongong or Mackay to Cairns and my worst nightmare is a flat tyre, we have an electric pump too and touch wood we've never needed it so far.

      3. Kylie Gilroy the space-saver is a last resort measure. Yes, it takes up room but gives that extra peace of mind. The pump is great.

        We have educated three people at Tyrepower (Monto and Gin Gin) who'd never worked on an electric car and had never seen a tyre with actual foam glued inside it. I keep a set of four pucks in the car for jacking, and spare wheel kit comes with one as well. Left front tyre now has two patches while the left rear has a patch/plug.

      5. Scott Howard we take our pucks to Bob Jane each visit.

        We have the Michelin pilot sport 5's on our car now, no foam but there isn't too much difference noise wise, handle really well in the rain.

  2. Use window cleaner to find the leak

  3. Is your frunk full? I keep my pump, UMC and first aid kit in the frunk so I can get to them easily.

    1. Chris Pegler Good call. I keep the charging stuff, shoes, windscreen squeegee, laundry etc in the trunk. But I keep tools, pump etc under the boot floor because they’re rarely used. This was the first time I needed the pump.

      I might reconsider 🤔

  4. It's just a nail or screw. You can drive on it for days or weeks as long as you keep the air up to it. Easy with a TPMS system that tells you the pressure. Just try and keep it above 30. You can even put 50 PSI in it to make it go further between re-airing.
    And don't use the Tesla flat trye kit unless you absolutely have to. The tyre guys absolutely hate it as it makes a mess inside the tyre and most times will want to fit up a new tyre rather than just vulcanising a patch over the hole.

  5. At least better for you with the rear tyre than the front as this messers with wheel alignment.

  6. I’m not being smart but why don’t you just pull into a tyre shop get fixed no problem

    1. Peter Warnaar Fair question. I figured that being such a slow leak, I could defer it until we arrived home, rather than trying to get into a tyre place during busy times.

      As it turned out, it worked not have helped in this instance. See upcoming post for the diagnosed cause.

  7. Yeah a compressor is a good thing to have no matter what the vehicle.

    I bought an aftermarket spare for my M3 which I take on extended trips - eg recently drove from Bendigo to Newcastle return. Like carrying an umbrella it guarantees no rain and no flat

  8. I made a full size spare tyre carrier that goes into the towbar receiver for long trips.
    I don't bother for trips on major hiways. I have the tin of tyre goo, compressor and plugs. I have only had a bolt and a screw both were slow enough to take it to a tyre shop, no problems, easy fix.

  9. Why do you have to contact the Tesla dealer for christ sales . People for generations have had flats and I doubt anyone ran back to the dealers , must be a Tesla thing .

    Reply

    1. Howard Thrift Not a Tesla dealer. The Tesla app has a “Roadside” section to report a flat tyre. Roadside assistance is included with the vehicle. Tesla then contacts a local service van (not necessarily Tesla) to bring a replacement wheel to the car.

      Stay turned for an upcoming post explaining how this worked for us.
