So, we had a flat on vacation in the 335i and had to put a stock size set of regualar (non-runflats) on the rear, while still having the stock run flats on the front. I noticed that now the car feels unstable and i swear almost feels like a re-steer. When going around a highway corner today at about 70, if a turn into it a bit more the traction control light flashed! So, I know its not just me. I more notice the instability at higher speeds (70-90), and its not bad around corners at lower speeds, but still not the same. Is this because of the difference in tire-types from front to rear? I know the run flats are stiffer, and weigh much more, maybe a rotational mass difference Im feeling? Im going to put the same tires in back on front, but Im curious to know what you all think if this will help balance it out more?
