 Ken,
 
 I changed to Goodyear 15X6:00 main tires exactly 1049 hours and 834 landings
 ago. My chickenscratching handwriting deciphers to 15 X 6:00 X6 or XC,
 depending on how you cock your head.  They fit. Looking at them, I estimate
 that I have only used 50-60 percent of their useful life. The Goodyear nose
 wheel has 722 hours on it but only because of an "incident", paid for by my
 local airports' insurance company. I seldom use hard braking. Hope this has
 been of help.
