An interesting range of opinions. The tires are new Michelin 205/60 MXV4. I beieve either these were OEM, or the Conti "rim protectors" (Mine came originally with the Continentals). I have asked the dealer to look at the front end, and everything appears tight. The comment about a "nervous" response" is pretty accurate..as a matter of fact the driver himself (:O)) becomes pretty nervous above 85 or so. Requires constant steering input and correction (slight) to keep it in the lane. The dealer is supposed to drive it tomorrow...will be interesting to see his opinion.
Thanks for the opinions..I may also try a different set of tires if the dealer claims this is characteristic.
