Complete Disappointment - RFT Tires are nightmare
 I purchased this Car in May, it is now October and I'm returning the car to the dealer and taking the loss on the taxes and extended warranty I paid for to trade it in for a different car. Almost $10,000 down the drain plus whatever amount that car has devalued from use. First of all, let me just confirm the complaints about the tires I see from other reviewers. They are a total nightmare! I have the receipts for 14 tires that I have replaced in the last 5 months. I bought 4 brand new tires at almost $500 bucks each after my first two flats. 1 had a bubble and subsequently popped within 24 hours of having it installed. I had it replaced with a new tire using the road hazard warranty and within a week, the two front tires blew out again. At that point I was driving scared and being extremely careful not to hit any bumps. Ive owned 2 door coupes with 19" wheels and thin tires and never had this problem. I even tried getting tires with a bigger sidewall to see if the extra cushioning would help and it only made things worse. The Car started to have an issue with the transfer case. According to the dealership the car has to use the specific tire measurements that come with the car or the transfer case gets confused when doling out power to the wheels. So basically I had no choice but to keep replacing the crappy run flat tires that costs $500. Ludicrous, I am trading in the car because the money I will lose from purchasing the extended warranty , does not add up to the cost of constantly replacing these tires. Other issues I had in my short time with the car are:The windshield fluid stopped working and pump had to be replaced. iDrive controller completely stopped working so the entire infotainment system was uncontrollable. Driver seat kept causing a warning that it could not be calibrated. Radio kept having a strange feedback noise at high volumes.All of these problems are minor issues that could easily be fixed by the very attentive and pleasant BMW staff at the service center. They were great and very pleasurable to work with. However it takes a month just to get an appointment at any BMW dealer in the New York area and some dealerships don't offer loaners unless you purchased the car from them.  When I went to the Service Center I was shocked, They had over a 500 Cars on the lot for repairs. Ive never seen anything like it. I previously had an infiniti and never had to wait for a service appointment or worry about getting a loaner. Not to mention the Inifiniti facilities are infinitely (no pun intended) better than anything I've seen from BMW. To say that I'm disappointed is an understatement. Im trading the Car in and trying out an Audi A7 or a Benz CLS.  Hoping that other German Car brands don't turn out to be all hype.
