Re: Possible causes of "twitching" in '94 S4?

[Malcolm White <M.White@sni.co.uk>]

My S4 suffers in exactly the same way as yours on undulating roads. Mine
is fitted with 245/40ZR17's and I find it almost impossible to sit in
the inside lane on most UK motorways at 50-70mph due to the constant
corrections and wanderings. This is chiefly due to the truck tracks that
occur over time in that lane. I can't understand why yours should be any
different as you have retained the same width. Whether the stiffer
sidewalls would contribute, I don't know?
