Hi again -
In reading through the many comments and "reviews" on the Tire Rack website plus this forum, I do think people have said that the tire has a bit more sidewall flex, leading to a slightly less impact harshness. I do think the additional 1.6% speedometer error is negligible. "Clompy" is my attempt at onomatopoeia since the thing I am trying to describe is as much auditory as a sensation through the steering wheel. It is just that the wheels and tires feel a bit "late" to react to the sharp edged bumps. The feeling is similar to the run-flat tires on our E90 in some respects. I was wondering how the different sidewall heights and stiffness, coupled with the larger un-sprung mass of the larger and larger setups would impact the ride and if anyone could comment on this effect.
This is all idle thoughts really...I will not be buying new tires for a while. One year anniversary of taking home the '12 Sport Ltd is next weekend and I just rolled over 12k miles, so we've got a few years yet.
