Hit 400 miles in my new M3P with pirellis and TPS went off for rear passenger tire. Filled it up to 42psi and next morning was down to 30 again.
Yep, you've got a hole in the tire.
As long as it is not within 1/2" of the shoulder, it can be patched.
Filled it and brought it to a nearby tire shop and they told me there's a nail in it and it can't be fixed since it's a run flat.
They lied, or are incompetent, or incompetent. All all three in one.
Tesla has never used run flat tires, but it does use tires with foam inside, making repairs slightly trickier.
Wasn't aware that they're run flats, but they more or less said I need a new tire. Going to try and find the nail/spot to see for myself.
Tires are NOT run flats, and you can patch it as long as the punctures is not in / near the side wall (statistically unlikely).
Should I bother taking it to another shop? Car has been cursed since day 1.
Statistically, most nail punctures can be easily repaired.
Best and most durable repairs require dismounting the tire, and installing a "plug" from the inside. In the case of Tesla OEM tires, removal/scraping of the stupid foam from the repair area will be required. This will be slightly more expensive.
If you are on the road, you can DIY the repair from the outside with a
DynaPlug tool. Amazon has them on same / next-day delivery.
You can NOT use "slime"/goo to fix the holes on OEM Tires because OEM foam will prevent the sealant from reaching the area of the hole. However, once you replace OEM tires with the ones that do NOT have stupid foam, you could and should carry
one of these with you for on-the-road repairs and tire inflation.
I have DynaPlug and sealant + pump kits with me in all my cars. Has kept me on the road and overcoming all sorts of puncture emergencies in under 20 minutes for 30+ years.
HTH,
