Some Silicone tyres leave a film or residue on plastic tracks.

Does anybody have any experience if the T3212 does that ??

How good are they on non-glue wooden track ??

Is this true??:huh:

On our routed track with smooth painted finish, our experience is that significant use of silicones will clean the track by removing any form of grip laid down by rubber tyres.

If everyone uses silicones, there is no problem, but if there is a mix of silicone and rubber tyred cars, the rubber tyred cars seem to suffer loss of grip.
:unsure:

So we have banned silicone tyres on our track.

The T3212 tires do not contain any silicone. The mix is SIMILAR to silicone in what it does, but as in the Ortmann tires, contains none. It is a compound based on urethane.

This we found out the hard way at Foster's. :laugh2: I had some worn down .820's that I had "recapped" with tube silicone.
I decided to give them a whirl for the heck of it on blue. Come race time the guy on blue lane slipped and slided around. In fact everyone did. One guy just sat out instead of running. We decided it was my silicone tires. Back in the 60's when GE came out with their silicone in a tube, I joined in and help cap all the racers who ran. We capped the Riggens and others with the threaded axles. The stock AJ's at the time were very hard, so capping spongies did the trick. Silcones were all that ran back in those days. Today, that isn't practical. A 10 or even 15 thou cap of silicone can wear out before the heats are run. Thicker coatings seem to result in too hard of a tire. I personally like running the silicones, but everyone has to!
You can quote me.
