I've had these tires fitted to the wife's car for about 2 years now, shes done about 8000 miles on them and they've still seem to have plenty of tread left on them especially the rears. all aspects of the tires seem very good for the price. I don't see the need to spend silly amounts of money on tires when these ones are more than sufficient and with the added bonus of Riken been part of Michelin and in my opinion the same quality.
