Always been a fan of using stock tires and budgeted for 20k miles on the front and 10k on the rear. Usually change prior to these ahead of a big trip. With the Dunlaps, the only time I've run a tire to the wear indcators I had 13k on the rear.
That said, this last time I went with the Michelin Commander II front and rear. Been about 5k miles, and I just measured the tread -- no measurable wear on the front and 2/32" worn on the rear. The local indy priced them slightly less than the stockers.
Handling is a bit different, with much more traction on curves and when leaned over and with less straight ahead tracking as the bike tends to wander a bit if i'm not paying close attention. Not real good on dirt or gravel but fine when the pavement was wet. No tire pressure indicated, only instruction is to use whatever is stock.
Bike is an '07 Dyna Super Glide, cast wheels, about 65k miles, and mine since new. Unless something drastic happens I will stay with the Commander IIs.
