Deformed rubber tires

Recommended Posts

Greetings everyone. Was wondering if anyone knew of a way to fix/restore rubber tires that have deformed from age/improper storage. I was given a few 1/8 scale kits and 1/12 Tamiya kits that have wheel issues. Replacements are sometimes hard to get and can be costly. I would like to try and restore these if possible. Any help would be appreciated.

Easy, just use an inner tube, or "Fix a Flat".? J.K.

Seriously, I had that problem. The weight of the built model was making the tires go flat. Especially on large scale kits.

What I did was pack the inside of the tires with florists modelling clay (the green kind that never hardens) and then attach the wheels inside them. They're still round to this day! Plus you can put a little flat spot on them for realism.

Hope this helps.

Thanks for some of the suggestions. One of my wife's colleagues is a science teacher and he suggested to soak the rubber down with a silicone and place them is a seal-able container for a minimum of 10 days. The 1/8 tire seem to spring back after a few days and looks pretty good, is a little softer than it was. The 1/12 Tamiya looks a little better and is pretty soft. At this stage if I add some foam as suggested to the inside of it, it should look pretty good. I think I will soak it for a few more days and post the results.

I wouldn't dream of letting this stuff get anywhere near my model parts. Before I even use the tires I will soak them in hot water and then wash them down in with warm soapy water.

Besides that, I always wash my model parts in warm soapy water before paint and assembly.

Silicone will cause fisheyes during any painting process...if you're not sufficiently careful. Handle siliconed parts with gloves that you throw away afterwards, and never EVER touch a model before ANY painting process after handling something with silicone on it.

Soap and water will NOT remove silicone, but a careful wipe with isopropyl alcohol will usually do it...from your hands as well as from your model.

It's good practice to get into the alcohol-wash habit anyway. You'll save yourself a world of grief.

Far as supporting larger tires that tend to go flat, the RC shops have foam inserts made just for it.

If cost is an issue, if you ask nice, you can probably get miles of this stuff free (after it's been used) from any local body shop. It's used to mask panel openings on real cars, to get a "soft edge".
