Depends alot on two variables- type of bike and type of riding at you are talking about. I can get anywhere from 3-5000 miles out of a set of sport tire on my cbr's over the years. I got 8000 miles out of my first set of michelin pilots that came with my first sportbike a cbr600f4i. I was learning both how to drive a sport bike and how that specific bike and was going very easy in it, since then the miles between tire changes have dropped with every new set. I think this is because tires have gotten softer in order to offer more grio and that I push the bikes harder now that I have a better understanding of what you can get away with on these bikes. I also have a 79 suzuki cruiser that gets it's tires changed every five years because I am affriad to go any longer due to dry rot or the possibility of dry rot, I once had the thread fly off arear on this bike due to the tires being so old. On that bike I have already acumalated 12,000 miles and the tire still had tread left just they were getting old so I replaced them, actually a buddy replaced them so he could barrow the bike to learn how to ride a motorcyle on that bike. Good deal for both of us, the bike got new tires an he did not have to risk breaking a new bike. I like Michelin Pilot Powers and have good luck with them over the years, while I have had a bad experieance with Donlup Qualifiers and would not reccomend them to anyone even if they are a little cheaper, they blister when driven too hard and while the grip was there I found it hard to trust the tires so I switched them out, sold them to a friend, who had no problems with them. Others I know really seem to like Perillis so to each thier own I guess.
Waaay complex question, dude. Depends on a huge variety of factors, including bike size, tire type and style of riding. Touring bikes, using hard-compound tires, can get upwards of 15K on tires (usually longer on fronts). Bikes are perenially hard on rear tires. Heavy bikes with lots of torque can got through rear tires in under 3K (miles). One other contributor has mentioned dual-compound tires. In some applications, those may work well. I, personally, have had poor results with them. Here are the basics: Heavy bike - quicker wear light bike - longer wear soft compound (racing/high performance tires) - quicker wear, especially through the middle hard compound/touring tires - longer wearing find a web-site/chat area that has the same bike as you, or an mechanic that is familiar with the bike for recommendations. Although often many manufacturers sell tires for a particular bike, often a particular brand will work best.
B - it comes from altered limestone or dolomite
On my Ducati 750 Supersport about every 6 months on Michelin Pilot Powers. That's everyday use like driving to work.
