You also now have another choice, the Michelin Lattitude available w/440 treadwear rating and in 315/35/20 and 275/40/20 sizes. I know soneone on here bought them but i haven't seen anyone report back on how they like em...seems from what I've read they may be the best bet for treadlife, ride quality etc. It will not be as good as the diamaris for ultimate dry grip. Just thought you might want to know...
