went to ride my bike to the store tonight. didnt make it 5 ft before i found my rear tire flat. dismounted the rear tire and pulled the tube off without removing the whee. found and patched the hole with the slime brand kit. put it all back together, pumped it up to 55psi and less then 2 minutes later... WhAM. total blow out while just sitting there. good news is it wasnt my patch that blew out.
