The new tubes are a dark blue and do change with the weather more than the orange ones did. If you cant find a problem with the good advice above you could ring one of the tube boys who post on here they are very good and should be able to help.
Heres my rib.
Thanks for all the advice just need a remedy now> The previous owner claims he had no problem with the tubes going dowm, Im lost!
