I recently put the 19 inch Nokian Hakka R2's on new Cyclone wheels and mounted them on the MS. They seem to be a little "squirrely" at high speeds. Is this just a factor of coming from the 21" performance tires? Is it driving in 60 degrees on dry pavement with ANY snow tires? Or maybe something else? The tires are the correct size and are inflated to 45 psi and torqued correctly at 129. The handling is clearly not as good as the 21's. At high speeds I would call it a "hunting" motion from side to side. Seems as though it's mostly in the front. Almost like yaw, or an oscillation in an airplane. Anyone?
