Thanks. The 35d responds better with the 21s. I didn't notice the difference as much with my old 4.8 with adaptive drive but here (35d) there is a clear improvement (sport pack without adaptive drive).

Found nails in two of the 19" winter (standard) tires. Good thing I have the wheel and tire package.
