I get about 2000 miles out of my Specalized All Condition Armadillos.
They grip very well and i have NEVER had a puncture in 4 pairs of them. And that’s with 15st of me on them.
I ride on some fairly crappy Scottish roads with no fear of being let down (pardon the pun).
I did kill a front one clattering a pothole, it developed a “snake” in the carcass straight afterwards but that’s not really a critisism of the tyre.
You can get bubbles under the tread when they are getting worn. This is due to water de-laminating the tread away from the anti-puncture belt. You only notice this on visual inspection, you can’t feel it when riding (maybe on Majorca you could but not around Glasgow !)
My new road bike will be having them fitted from the word go. An excellent tough tyre.
