Well, I discovered a tire bubble on the front driver side. I have a 2014 MCS with run flats. Unfortunately for me, I do not have any additional tire/wheel warranty. I took my car to the dealership today, Saturday. The dealership do not do anything more than maintenance work on Saturdays, they would have to replace the tire (or two) on Monday.

The good news, instead on me driving on a potentially dangerous tire, my dealership offered me a loaner for the weekend. I thought that was a great gesture.

The bad news, my loaner is a 2015 MCS without the HUD!!! I just realized how HUD-dependent I am now. Arghh

 

I have replaced two tires on my 15...have since changed to after market tires and rim...hit a nasty pot hole last week. Checked the tires thoroughly yesterday with no bubble...glad I swapped
