general problems of the 2009 BMW X5

Sir, BMW installs runflats on all their cars. On this X5 I've replaced these tires 3 or 4 times at my own expense as runflats either get puncture or leak and one can't replace @3/32 oly one. These tires are defective and have not served this SUV well. In fact, my wife's bm@ 535xi I did the same and threw out oem tires with new michelin and spare. Bridgestone has a warrranty if within 3yrs they will replace @ very large prorated discount. I've spent $270 each time plus headaches of breaking down in phila or in nyc on way to pick up wife from jfk @ midnite. File size is over 5gb so how do I load it???.
