Just peered at the Tires on Ol' Maybelle. 5000 miles. The last 1200 of these miles are on the Big Motor, and obviously, I've run her a lot harder. I can see a few flat spots, but nothing noticeable in feel, or sound, as of yet. I dropped from 40 to 38 in the rear, and from 38 to 36 in the front. Front looks like new, btw. I'd say another 1000 or so miles, will be the life of that rear tire. That's about 2000 more miles than I ever got out of the 16" on Ol' Maudie. Big torque shortens the life of a rear tire. Just another flea that comes with a "modified dog." I don't ever do burn-outs, and the only time I power-shift is when neccessary, from 5th to 6th. I think I stated somewhere I might consider Michelins next time, but I doubt it. Pretty much set in my ways about MC tires. I tried AVONS and Metzgers one time way back, and was very disapppointed. Compound seemed too hard, to me. Dangerous in the rain! Nothing grips like a Dunlop, rain or shine. To me, anyway. Later--HUBBARD
