Regarding the advice to carry a plug kit/pliers and skip the sealer: not everyone has the ability to do the work on the side of the road. I've just recently used the sealant on a 24k mile used tire (Nissan Leaf) and it worked exactly as advertised. Yes, follow-up was inconvenient, to take the car to a tire shop, remove the tire from the rim, flush out the water-base sealant, plug/patch from the inside, remount, balance tire. The TPMS wasn't affected by the sealant. 1500 miles later, tire hasn't lost a breath of air. The convenience factor, for anyone not mechanically inclined, is important. (I would prefer a full-sized spare, as the sealant is worthless, of course, if there's a blow-out!)
