Just bought a bunch of Vittoria Corsa CX tubs off ebay, all seemed ok when they arrived and had been folded as per when new. But on fitting them on some spare rims they were full of bumps at the folds. Pumping them up to 7 bar and leaving over night did noit improve them. So I got out the hair dryer and warmed up the bumps, guess what?? they dissapeared and all the tubs are now completely round.Hope this helps anyone else and saves having to throw them away.
To repair them at home myself. Sometimes there were some very good ones in between.
