Hi all, I'm new here, so I hope that this works! I didn't realize the tire controversy until the icon blinked and beeped and got the "bad news" to replace all tires! I only have 14,000 miles on the car! It was just serviced! They said my inner tires have run bald, but the thread elsewhere is OK...ouch! So here's my dilemna, besides having no power, do I stay with run flats or go to a non run flat and get a donut spare? If I stay with the run flats do I stay with the factory model, a dunlap tire, SP Sport 5000M 245/40ZR18, (Lex code: 000989) or can I jump ship to the one COSTCO has, a Michelin PS2 245/40R18 (item # 311951). And what's all this talk about thread 1, vs, thread 2, vs. thread 3? The dealership says that they have the thread 1 and COSTCO and others have inferior tires???? what's better, the Dunlop or the Michelin?
