hmm..., different stories all over the board (and other forums as well)
just used up a set of 'stone 021's on an '03 FJR. at 7,000 miles.
2,500 up and back to Hyder Ak (from Seattle), mostly straight up, 70mph stuff
2,500 mi blitz to Yellowstone, Beartooth Hwy, Sunlight Basin, Teton Pass, Lolo Pass and lots of hard riding in the twisties.
1,300 hard miles in Lower central B.C. Kootney's w/ lots of twists and turns.
700 mi. various stuff.
...lots of high speed open running mixed in here and yes, front did flat ctr. early but never seemed to be to the detriment of handling. No rr. "chicken strips" and minimal fr. "chicken strips". I'm usually following another rider who is very fast but very steady and smooth as well. No aggressive launches or extreme binder grabbings.
Heat??? At least half of those miles were in the 80* to 100* temps this summer.
ride 1 up, semi lightly loaded, fr 39 psi/ rr 42 psi (always)
The last 500-1,000 miles the front was near the wear bars, rear still maybe good for 1,000 miles. Today I pushed these tires very hard coming home over the North Cascades Hwy.. The tires stuck like glue and handled great even when well worn. Always handled better than 020's, Pilot Road 1's, Conti R.A.'s, & Pirelli Diablo Strada's.
I have always tried a different tire and will try the Pilot Road 2's or Dunlop Roadsmart's next but I was quite satisfied with the 021's performance right to the end. If I can match this handling and get longer tire life/mileage, I'll be quite content.
This is no "assault" on other folks experiences or comments... just another perspective thrown into the mix.
