Quoted from eyeamred2u:Only get chewed up if you put the wrong size on it like most OPs do.
I don't get it though, if the post is so close that the ring is hitting it, how could any size rubber on the post not get chewed up too? I was planning to use my dremel to grind a semicircle out of the ring so that they don't touch at all. Here's a pic of mine, you can see how the side of the post is worn down and how the post has worn the edge of the ring. The hole for the post is in the same spot as other T2's, right on the outer black circle.
