Those are excellent tires, I was aboout to get a GT Radial tires , thay are made by yokohama but I loook at thses sumitomo at a great price and the 100K miles on warrantie and the price is hard to beat. I change my bridgestone OM tires for these Sumitomo and could not be happier, I live on a the Sonora desert so most is a dry drive, so far in highway the response at 75-80 mph is great no need for higher speed with the family, good grip on corners at 75mph. I have not test them on wet but here almost nevers rains. Noise and smood level is very good better than the OM tires. so I will buy them again for sure. I use to be Yoko's fan (still) but Sumitomo quality/price is excellent. If you are a average driver or the wife-family car this are a GREAT tires for sure, if you want to speed buy tires for that.
