Had a slow puncture in my front TKC since The Vince in July. I pump it up on Sunday night to 3 bar for commuting to work and by Fri night its down to 1 bar. Cant be fekked to fix it as not a lot of tread left.
I was thinking if the crack is a worry, a good quality tyre goo (apart from stopping punctures between tread blocks) will slow the rate of air loss through any developing major fault.
