I picked up my M3 on July 28, 2018. This is my first car without a spare tire. After doing a bit of research I have put together a kit for my M3 to deal with a flat tire if roadside assistance is not an easy option. My kit includes: Viair 88P Compressor (Purchased on Amazon) Slime Deluxe Tire Plug Kit (Purchased from Walmart) Milwaukee 6 inch Long Nose Torque Lock Pliers (Purchased from Home Depot) The Viair 88P hooks directly to the 12 volt battery. (Red first, then black.) I tested it by deflating my front left tire to 19.5 pounds and then re-inflated it to 42.5 pounds. I left the Tesla "on" by leaving the driver door ajar. The compressor worked great and inflated the tire in a minute or two. (I didn't time it.) This compressor is probably overkill, but it was not that much more than lesser models, is definitely cheaper than the official Tesla model, and I don't have to worry about drawing too much current through the cigarette lighter plug. The long nose locking pliers are to pull any nail or screw out of the tire. Not pictures is a pair of leather work gloves and a knife I keep in a tool bag in the rear trunk. Hopefully I never need to use this kit, but I drive from Phoenix to Los Angeles and San Diego three or four times per year, so better safe than sorry. .
