Tire Tread

[Melalvai]

My armadillo tires came with arrows. I thought the idea was the kevlar is in overlapping scales, so one way would allow nails and such in easily, and the other would keep them out. I could be completely wrong though.

Susan - thanks for the link for it answered my question. It does not really matter which direction the tread goes.

Melalvai - I don't know about the overlapping scales. All I know is I got nearly 10,000 miles out of the last set of Select K's I had on my bike so I figured I would stick with a good thing. I think I had one or two flats during those 10,000 so I think the kevlar did its job.

Just so you don't lead anyone astray, this applies to ROAD tires.

MTB tires, oh yeah, you need to pay attention to the direction.

I cannot imagine a company going to the trouble to make the Kevlar belt in "scales." At least, not and sell the tire for a reasonable amount of money. It's far simpler to lay down a belt over the tire cords just before applying the tread compounds.

Yep, tread designs (at least on road bike tires) are mostly marketing tools, there to give you a visual difference between two tires that otherwise behave much alike.

And Select K tires are good ones, especially for the money (<$30).
