I just pulled a set of tubeless 700x25 off. Front tire still had the wear indicators intact, the rear tire didn't. Rear tire however had a large puncture that wouldn't seal with a plug. Rubber was also starting to bubble around the puncture.I replaced both as I don't like riding with one new/one old. Had about 1500 miles on the pair. Hoping the next pair will get a little further than 1500 miles.
