I bought a 2007 Prius Touring Model and have put 56000 miles on the car in just over two years. My tires have about another 5000 miles on them but today I found a gash about 1.5 inches long and it appears to be down to the belts so I will be replacing the tires early. The tires have been fine. I periodically checked tread wear has other OEM tires (other vehicles) didn't last so long. I am happy with them and plan on replacing them with the same tire type.
