I noticed a common verbage "so far so good " from a few of the threads sometime ago I used a similar phase on another post myself unfortunately at 17000 miles the rear tires are worn smooth front still shows a little milage remaining the original Contri got 28000 miles and were replaced with the Goodyear in discussion here these were on my wife's Ltd roadster and while she is a fast car driver "wantabee" there is no way you could say her driving habits caused the quick wear i.e. 28k on the Contri for those now using them good luck and check as you get more milage for those looking I would not buy another set
