These replaced well worn Yokohama s.drives in the same size, mounted on Mazda CX7 OEM wheels 18x7.5. The s.drives had 35K hard heat soaked miles on them, were zigzag cupped on the insides (bad rear toe) and very thin inside compared to outside, perhaps from the MZ3's stock negative camber. Noise and dry grip are dramatically improved, as is the ride comfort, keeping in mind that any new tire replacing a worn and heat cycled tire will almost always be quieter, grippier and softer riding. The Las Vegas heat is brutal on tires, and it so seldom rains I cannot comment on and wet performance. I also can't comment on tread wear as of yet. So far and am very pleased I spent the extra $1 per tire over a new set of s.drives. This was all thanks to Tire Rack's excellent customer survey system. As I look back at all of the Yokohama tires I have purchased here at Tire Rack it seems all Yoko's get extremely noisy with age. Maybe a brand trait? I only thank the Good Lord that Tire Rack does not have a button to click on that tells you how much money you have spent total on tires in your life time!
