12th on Concrete: what tyres?
http://www.morcc.com.au/smf/index.ph...sa=item&id=255
This is a brand new surface, which I believe to be basically smooth concrete.
Some of us want to run 12th scale on it, but where to start in terms of tyres is difficult to know.
I'm fairly certain caps will be necessary. But who is making caps these days, where do you get them, and which foam/cap compound is a good starting point?

I don't know that even caps are going to give you useful traction on a surface that smooth. I have heard that there was a time when foam tires were coated in liquid silicon and allowed to cure to allow racing on polished wood surfaces (like a basketball court). This would require a dust free surface to be sure. Hope that helps.

Our indoor concrete track we used sugar water and it kinda sorta worked. Traction was good until the sugar coated the tires and they looked more like glazed donuts. You are really going to have a hard time getting traction even with caps on a surface like that without some sort of treatment. Problem is the treatment will stick to the tires about as much as it does to the ground.

1 assume by 12th he means 12th pan car...in which case I'd be really interested in how he would get camber in the rear suspension

oh, and that surface actually looks like painted concrete? fantastic!
what do you want traction for anyway?

sugar water or some other traction spray on the surface

Seriously, try coating an old set of tires evenly with Shoo Goo or silicone sealant(RTV). Use an expired(of course) credit card/gift card to apply and smooth.

duct tape?
wait, double sided tape?

Some sticky hair spray or vax perhaps.

Ok, so coat tyres with silicone rubber then. Is there any way to tune the grip level from there apart from the shore of the foam the silicone goes on top of? Do different silicone coatings offer more or less grip, and if so is there a guide as to how to tell? I presume we're not going to want to have the same grip levels front and rear.
