Hi, can anyone advise where I can find pneumatic type wheels (including the attachment, a threaded stud, to fix to the trolley base) for a dog show trolley? I'm looking for the 6 inch size, or similar, the exact same type that are on the Redcape dog show trolleys? Thanks so much if anyone can help!

Could try asking Redcape or they should be available to caravan/trailer camping outlets who even if they do not keep them in stock should be able to get them for you as they are used on Jockey wheels.
