do teslas have a spare tire

Short answer: no, Teslas sold in Australia don't come with a spare tyre.

Instead you get a sealant-and-inflator kit and roadside assistance, which is terrific until you grenade a sidewall and the goo throws in the towel. If you're allergic to waiting for a flatbed, carry a proper plug kit, a portable compressor, and jack pucks for the battery-safe lift points. Some owners buy an aftermarket space-saver, but check wheel size and brake clearance, especially on Performance models with big brakes. For anything nastier than a nail, call roadside and let them earn their keep. Keep pressures in check and you'll avoid most of the drama.
