I purchased 4 of these Yokohama AS 430 tires from Town Fair Tire about 4 years ago. I have put on 30, 000 miles since and it looks to me like the tread has worn quite evenly. I have rotated them as recommended a very important aspect of tire care. Without doing that tires wear very unevenly. Supposedly with proper care these tires are said to be able to last in the area of 70, 000 miles. They have a great ride and my experience in the rain and snow has been positive. The traction is very good under those conditions. When I purchased these tires I found myself thinking that 104.00 per tire was pretty expensive. However as I look back over the last four years and evaluate the overall performance and then take a good hard look at the tread wear at this point I have to say they were worth the money. I had heard that Yokohama has a good reputation and I do say that I have not been disappointed. I would certainly buy tires from them again as well as recommend them to anyone who is interested in a high performance tire with a long lasting tread.
