Regarding the self-sealing tyres:

ContiSeal seals damage from nails and screws
Developed by Continental, ContiSeal technology allows a vehicle to continue on its way even after a tire has been punctured by a screw or nail. A protective layer on the inner side of the tire tread immediately seals the puncture so that no more air can escape. The seal functions well for virtually all punctures up to 5 millimeters in diameter, which means it covers roughly 85 percent of all flats typically occurring. Sometimes, in fact, it functions so well that motorists don’t even notice that a foreign object has penetrated a tire. For this reason, Continental recommends that such tires – and all others as well – be checked regularly for nails or screws. The new, sporty Volkswagen Passat CC will be shipped exclusively with ContiSeal tires.
Sounds like sealing to me.
