Thanks Fred for the photos. The wear bars are even with the tread in the very middle but it builds as you go outward from the center. I'll keep an eye on it. I paid $165 for my rear Pirelli Angel GT A-Spec so not too far off from that.At the very edge of the tire tread area are little directional arrows molded in that show where you should be able to see the three wear indicators. Because I do not commute, and generally avoid riding the slab as much as possible, I tend to wear out my tires first at the red arrows. As you can see the tread in that area is more worn than anywhere else. You can also see that, although my peg feelers remain unscathed, I manage to get over onto the edges of the tires every now and then.
I have never yet worn out the center of a PR2 before erasing all tread in the area shown by red arrows, and that includes the one that is still on the '05 now after running lots of slab back and forth to Montana and Wyoming in 2014.
I still expect to get another 2000-2500 miles out of the above tire (to around 9k miles) if I do not replace it before that for the state inspection due at the end of this month. Guess what tire I will be putting back on there? For the price these things can be bought for ($140 shipped from Jake Wilson) you really cannot beat 'em with a big stick.
PS - I still think your tire looks fine.
I'm still considering a darkside transition but that will be after the NAFO event. Thanks again everyone for the help.
