in response to: "what regular all-season treads should I put on my 4000s (non-q)?" The common wisdom seems to be BFG TA-HR4s. Supposedly very good tire, modest price, good in wet, as good as can be expected in the snow. Available 60 and 70 series. Eagle GAs are fine, but overpriced. Most Michelins are very quiet, high quality, poor in rain and snow. Grant
