Bummer! In terms of the process, I think I got it pretty much spot on: put a reasonably thick layer of glue on the tire basetape (which already had 1 cured coat, the rim 2 coats), pumped it up just a little, and fitted it keeping pressure to stretch it. The Veloflex Aernberg 25mm tires (prestretched on clinchers) went on quite easily and I was surprised it didn’t get much glue on the rim when stretching the last section, though the top edge of the rim did scrape off some glue which then stuck to the sidewall of the tire. The nitrile gloves I was using also stuck to the glue on the tire sidewall and ripped off – are there other gloves I should be using? I then inflated to 40psi and tried to centre the thread, which was very difficult and then when I felt I had to cut my losses as moving the tire was becoming very difficult, I rolled it along the ground with my weight on it and then inflated to 9bar max pressure and did the same again.
White spirits managed to remove much of the glue on the tire sidewalls and overall I felt it was a reasonably neat job.
All except the important bit: I think the way I glued the basetapes for their first coat came back to haunt me. I had laid the tire on a horizontal surface, inflated to about 30 psi, and then rolled it so the basetape was pointing upwards for easy access for glueing. I then rolled it back inwards, but it may have stayed a bit kinked. Net result is the thread is off centre by a few mm. In most places it’s a couple of mm out, but in one spot is a bit more. I couldn’t see how to attach photos to this post so uploaded some to this folder: http://sdrv.ms/XdPgij
. The pics are fairly poor quality but should show what the thread alignment is like for the majority of the tire with one photo showing the worst section of thread alignment. So my process seemed good but my execution was poor.
Given how long this all took to prepare and do, I can’t fathom the idea of doing it all again unless it’s critical as I just don’t have the time or will. I’ll put the wheels on the bike tonight and check that they’re smooth and not bumpy. Should it be fine to ride these tires or will the thread being off centre affect grip (safety), performance, or puncture resistance? If the answer to any of those is a resounding yes, I may come around and think about redoing it. But if it’s more a case of ‘you’ll get away with it, but ideally you’d redo it’ I’ll just leave it be.
The pics don’t do the wheels or tires justice, they look great in the flesh and now I’d really like to just get out there and ride them, with a race this Sunday being their first big outing.
