replacing all 4 or just two?
If just two, condition of one pair to the other(tread depth)?
Basically, you are going from a wider tire, to a narrower tire, that will have a slightly larger diameter......so if 4 tires are replaced, there will be no problem as abs speed sensors are concerned.....it will affect the speedometer slightly...possibly a couple mph slower than actual....
However if you just replace two, I don't know if the difference in height/circumference will be enough to trigger an ABS/TC light because of the variance in speed(tire rotations....the larger tire in circumference, will spin slower, causing an abs speed difference between front and back)......whether this is enough of a difference, I am not sure....
