I realized as I left work one day last week that I had a tire that was low (TPMS don't read until you start moving) so I stopped at the gas station half a mile away and bumped the pressure back to normal with my tire pump. There was no obvious source of the leak so I proceeded home where it is easier to work. I removed the wheel when I got home and discovered a nail at the inside edge of the tread. I always keep a plug kit and tools to remove foreign object in the car along with a tire pump. It would be a pain in the butt to do this on the road side depending on where in the tread the foreign object was, but acceptable in an emergency, I am just glad I was able to do it at home instead. I went ahead and put a plug in the tire, but since the hole was very near the sidewall, and the tires only have another 5,000 miles of use on them I went ahead and ordered some new tires. They get delivered tomorrow, and I will get them mounted my next day off (this Friday). I went with a 235/55/18 Michelin Primacy MXM4. Same tire they use as OEM equipment on the model 3, but with a taller sidewall and HL load rated for use on the MYP. I am expecting a bump in efficiency compared to the 245/55/18 Continental contisport 3 summer only high performance tires I am replacing. Also, the speedometer will go back to being 2 mph faster than real speed as measured by GPS since these tires are the same diameter as the 245/45/19's that are factory spec for the Model Y. Since they are a different size than the stock Model 3 tires (they are OE for a Volvo, not sure what model) I am not sure if they have the accoustic foam inserts... guess I will find out when I get home from work tomorrow
