Strange things with Revell tyres

[alpina]

hey there,
I was dusting off some models in my closet. When i came to the the merc A160, the tyres where standing in pools of oily stuff. Tyres had flat spots and the rims where covered too. Don't know where it comes from, maybe some solvent that came out of the rubber? Any suggestions?
I bought the kit about 5,5 years ago.

grtz, Ronald

So, THAT'S where my extra sludge went.......

I think it must be something to do with the rubber or whatever they use. I have found that the tyres on my revel integra and civic stick to the polystyrene sheet I sit them on in my storage boxes, they seem to be the only ones that do.

I have a Revell mustang that I put together 2 years ago, before I even knew you could modify models and crap- I was like 14 or so, anyways it hasn't done anything wierd yet. It sits in my room at room temp, but sometimes hotter because the summers in vegas = HOT

I have no idea what Revell uses for tires, but frequently it's not chemically inert. Tamiya and most of the Japanese manufacturers use silicone. It's expensive and difficult to cast, but takes tread detail well and is entirely inert (probably hypoalergenic, too ). Revell obviously uses something else. Horror stories of Revell or Monogram tires eating bare styrene are not unheard of.

I had that on the old 1/16 Gullwing Mercedes, the rims turned in to a sticky mess. I've heard that the plastic should be protected with paint all around to be okay from the tires i.e. even the inside of the rims that lays against the rubber. The rest should be okay as it has no direct contact with the tires.

I've got no problems with melting Revell-tires. The ones on my Revell New Beetle just broke in pieces after two years. Weird. Luckily Revell Germany replaced them, but guess what happened after two years...
