Why does my BMW have run-flat tires?
For years, BMW has used run-flat tires throughout their entire model lineup. In concept, Run-flat tires are a great alternative to the added build cost associated with spare tires. While run-flat tires allow you to continue driving when a tire loses air pressure, there are trade-offs to consider.
You may already know that Run-flat tires are typically more expensive, have a shorter tread life, have a harsh or poor ride quality. Furthermore, run-flat tires are often considered unrepairable once used without air pressure for any significant distance.
