I have a family member who just recently purchased a 2015 BMW X5 with 54k miles, the previous owners was the original owner and my family member is the second owner. The X5 has always been dealer maintained, and my family member just went into the dealer for an oil change and the tech stated that the car would be due for tires by the end of the year, maybe the beginning of 2021. The dealership also stated that this X5 has already have 2-3 other sets of tires on it, so by the time the car is ~60-70k miles it will have had roughly 4 sets of tires. Apparently you 'cannot rotate the tires', and my family member does not drive the car hard by any means and the car does not need to be aligned. With all of that in mind, would you still recommend top tier tires knowing that the car eats tires for breakfast? or just go for middle of the road tires and save a couple hundred bucks? TIA!
