Hi

I have a couple old Italeri opel blitz kits in my stash, in the past there have been issues with the rubber/vinyl tyres melting the plastic wheel hubs after a time.

Unable to purchase a replacement resin sets (high cost) do you have or other members have a solution to
to this problem.

Regards

Michael

didn't know rubber or vinyl interacted with styrene? Hmmmmm. wonder if you could coat the hubs with something before assembly? do you glue the tires to the hub? if so, maybe it is the glue reacting with the rubber/vinyl and attacking the styrene hub? Do you think that PVA glue would protect the hubs from the rubber? another question: are the models stored in a hot location? I know that rubber can become sticky over time if exposed to heat. Perhaps put tape around the inside of the hubs and PVA glue on the other part of the hubs when attaching the tires?

Thank you Ted,
I am unsure what the tyres are made of, Assumed that they were constructed of some kind of rubber/vinyl. Thinking about the problem it maybe the very old styrene 30 years plus. 
Having checked other models awaiting to be constructed (still boxed) the same issue of the two materials reacting against each other, to reduce further deterioration the wheels have been separated from the styrene.
Your suggestions maybe the best way forward, to form a barrier between the different materials.
Once again thank you.

Hi Mchael, have you considered making your own mould?
A low complexity part with a negative profile is a very simple process and fairly inexpensive.
