i've got some new wheels on the bike, and the rims are running true. but the tires... yikes! they're quite a bit out of true!
to what degree is this normal? to what degree should i be concerned?
is it time to replace the tires? or should i keep running them until the tread is worn down? or other signs of terminal wear?
the tires are schwalbe marathon kevlars, 700x35. i've been running them for almost three years on my commuter. there's still good tread left on them, but they have seen a few big punctures early on, and one or two tiny shards of glass have worked through since then.
