My 2001 325Ci convertible comes with Michelin MXM 91W tires in size
225/45R17. Car still has OEM supplied tires except for two replacements due
to tire damage. Car mileage is 39000 miles (low). I just had my 3rd tire
These are low profile tires and I have had unexpected loss of air a total of
3 times in the life of the car. Each time the tire was destroyed and have
been replaced twice. They have been replaced with the OEM type tire at a
cost of $275 a pop.
1) Why are these tires being damaged like this? Is it the low profile? Is
air pressure critical where sidewall wear can result if the tires are even
slightly underinflated? I think folks with low profile tires like these can
help answer this question. To my knowledge there have been no pothole or
2) I believe that if I replaced all 4 tires at the same time, there is
likely a tire that is much better than OEM, and at the same time more
cheaply priced, that I could buy. By having only one tire to replace at a
time, I feel I am captured into buying the OEM type tires at a substantial
price. Comments? Are there other tires in this size that are less
expensive with equivalent or better performance for the simple grocery
getter driving that I do?
Thanks for any and all replies.
