This is to inform all my BX friends that I am leaving the one flat front tire group

[ultrarunner]

I put a tube in my tire last winter. Drove over a couple pocket gopher mounds a few weeks ago and came out to find a flat the next day. I cracked the valve stem loose from the tube. Not expensive to fix, but a PITA....

I really think a lot of tubes today are junk...

My old cars all have tubes and never a problem with Kelly Springfield and similar...

Some of the tubes today split right at the seam... frustrating... then they all come from China.
