1-- No clue. Never worn one out. 2-- Just ride easy. I've had two brands new bikes with brand new tires. It's not like they're covered in grease. Just don't go anywhere near the limit for a while. Or ever, really. 3-- It would have to be registered. Not without a VIN. Start with a VIN'ed frame, just keep the vin plate. 4-- 7 years. Still have my first bike. My riding style changed so I got a bike more fitting that style. (commuting and long trips instead of sunday cruising) 5-- No clue, Sorry 6-- When all else fails, a cellphone and a AAA card with bike coverage. Beyond that, the factory toolkit and a tire plug kit should suffice for most stuff.
