Hello, I got a flat yesterday, but was able to work on it at home fortunately. For practice, I decided to use my roadside screw jack instead of the hydraulic racing jack. Screw jack went wonky at about half the height I needed to get the tire off, so I put the car down, swapped in the hydraulic and did the repair (plug worked great). The scissor jack was one of the $25 amazon "2 ton" deals - but definitely won't cut it. I've searched the forums here and elsewhere for someone who wholeheartedly recommends a jack for roadside emergency work and can't find one. Anyone happy with what they've got? If so, which one? p.s. Tesla roadside tried finding me a loaner wheel, but couldn't. I was gonna have to get towed to the SC if I wanted their help. I pulled the puncture ( a small 1/8" hollow tube, oddly enough), it closed up enough to re-inflate to drive the 1/2 mile home, where I did the repair.
