I really cannot see the value in having a tire inflator kit for these self sealing tires. Only time might help were if there was a small puncture in the side wall, and that has to be a very rare problem. Larger problem like Ladogboy had would not have been fixed by goo and inflator kit. So I am fairly confident driving around on these tires, going "naked" except in that situation where you may be going on a trip where cellphone signal is spotty, as OnStar also relies on cellular signal...not satellite. A small donut tire, tire tool, and jack would make all the difference here. Would save HOURS if not days. Took Ladogboy more than a day with his situation.
And these OEM tires are currently back-ordered on Tirerack. Not so easy to come by. We do know the specs, just waiting for someone to create and market a usable donut tire to throw in the garage and put in the storage area for those mission critical trips.
