I have Bearclaw HTR’s on DPS rims that have been leaking around the rims since new (3years ago). Tires were sealed at least three times by dealer over this period and all but one keeping air for more than a day. Last time was two weeks ago and they were flat next morning… Tired of inflating all the time. Should I try to slime them before going to last resort of putting a tube? Any other suggestions?

Thanks for your help.
