rc feen .. yes they are dyeable.. I just dyed mine a navy blue... they turned out great... put the clothing dye in boinling water.. simmer... and put one wheel in at a time.. I put in about 1/2 the small container of dye to a pot of water... make sure the rim is all covered... I left mine in for 15 mins.. then into a pail of cold water... if you leave them in the hot water longer or add more dye they will get darker.. you may have to add some water or dye after the first 2 rims.. all depends how much is absorbed in to the rims and how much water steams off.. hope this helps you out.. I have some pictues of mine.. I will get them sent out on Tues.. Garnet
