I have owned this vehicle for 1 year and three months. i did not have the choice of selecting any other tire. mini cooper( bmw) put run flats on vehicle because there is no where for a spare tire. i keep the vehicle in the garage at a condo in florida with no access to anyone. i have 4250 miles on the vehicle. i have had three flats. mini related that i had the opportunity to buy a tire and suspension warranty when new for 800.00 plus dollars. i can't remember the last time i had one flat on any other vehicle. my wife or i have used this vehicle for less than 5 months and this is the third flat. mini denies any deficiencies with the tires but i don't believe them. this averages out to a flat about every 1400 miles. my father got better mileage out of retreads. statistically it seems significant and there is a defect. please investigate and respond. *tr
