i got 36,000 miles out of my front tire. it still had plenty of tread on it, but i started to get a wobble, so i decided to put a new tire, tube, baLance and trued. the dealer said they never seen a tire with that kind of miles on it that looked that good.
wow...on my 06 FLSTNI, i got 20k on my front and 15k on the rear, yes the front wobbled when i let go of the handlebar, that's when i said, time to go...36k...that's unheard of...
It's f'n sweet to get that many miles out of a tire before it causes any problems. I have a new front tire coming. I got 15k on my tires and the front is cupped badly.
