In Reply to: Lexus E300: Is Pirelli P600 "H" M&S okay? posted by Cliff Denker on December 09, 1997 at 19:06:43:
Unless you plan on cruising above 130 MPH, an H rated tire is fine so long as the load rating is satisfactory.
Vehicle manufacturer's will tell you that you have to have a tire that matches the speed capability of the vehicle
so that some fool doesn't put Acme Cheapo tires on and then sue when he has a blowout at 150 MPH. In general, the
speed rating doesn't have anything to do with how the tire will perform in "normal" driving. All you are "giving up"
is a tire design that will dissipate heat and hold together at some absurdly high speed depending upon the rating. In fact, for
general driving, a higher speed rating may have disadvantages in that higher speed ratings tend to go with "performance" tires which tend to be
tailored toward dry handling at the expense of snow grip, noise, harshness and mileage. Check out some of the tire manufacturer's web sites or
someone like Tirerack. They have a lot of information.
I had some flavor of P600 a few years ago and it was a fine tire. However it is OLD tire technology. The P6000 SportVeloce is
much newer technology and should be much better in rain and snow. Probably more comfortable also. The P6000 SportVeloce should
also wear about 23% longer than the P600 M&S based on it's treadwear rating.
