hi all i have not tryed this yet, however my friend has.
he was trying to get smoother and had no way of doing it so i told him to have a really low psi in his tyres and do all his normal gaps and drop ect and try not to rim out. So he done that for about 2 weeks and gapped and droped over and over again now he is realy smooth and back on his normal psi .
so it may not work for all of you but it did him so just give it a try one day and see what happends.
hope it helps
