What's the normal lifespan for the stock tire?
Still riding on my stock tires... only get to do intense curves do to the rain about once a month, used to do it every weekend or every other weekend on the heavy curves (and I love the curves!). But, mine still look decent... was thinking around the 15 to 20k mark is when I would have to replace them... I also tend to do the zig zag pattern down the road to make sure I wear down some of the side tire compared to the middle of the tire, to make it last that much longer... Sometime today or tomorrow I'll grab my high resolution camera and take a pic of the tread on the back tire for all of you. The front is still looking good though.
As far as Metzler, I have noticed that Shane's wears out reasonably fast compared to the Stock Dunlop, but as discussed in a previous thread, that is do to the different types of rubber used in the different tires (softer rubber vs. harder rubber). The Metzler does grip better than the stock Dunlop though, so there is that up and down disadvantage/advantage to it.
