I had a set of BB's for years and they never lost air but did have a big crack where the tread met the sidewall. They were sold as a set with wheels and the current owner still uses them. Going on 7 years!
I have another set that's 18 mos old with the same big crack along the tread/sidewall. Never had any air loss issues. Just waiting to get some pics done before I slap Avons on there.
For those that lose air - how old were they when it started?
