You're comparing apples and oranges (and peaches) here! First, an "M rated" tire is likely an all-season "Mud & Snow" rated tire. It could have an S, T, H, or any other speed rating (though likely not a V rating). Trying to compare an all-season tire to a performance tire is not a fair comparison. You already noted that the V-rated tire would not work well in snow... Second, you can buy some tires in an H or V speed rating in the same brand, model, and series. That is where one would be able to do a legitimate comparison between the performance of the H- and V-rated tire with all other things being equal (though, admittedly, it would be expensive). I suspect there would be much less difference than you think. In fact, it is possible the H-rated tire would perform better on wet roads or in other conditions due to the different tread compound. Third, aspect ratio has as much influence on cornering ability as the tread. If you went from a 50- to a 60-series or 60- to a 65-series, V-rated tire, you would notice a distinct performance difference despite the identical speed rating. Finally, there may be a distinct performance difference between 2 V-rated tires by different manufacturers, or in 2 different series by the same manufacturer. The speed rating is not a performance/handling rating -- it is only an indication of the tire's resistance to tread separation at high speeds. ----------------- John Weiss Seattle, WA remove *nospam* from e-mail address for reply B <Bnopsamm> wrote in message news:848h67$9uh$2nopsam.pconline.com... > I own a 1996 CSE and recently purchased Michelin's MXV+ (M-rated) as > recommended by my friends at the SAAB service department in my town.
