I thought I read through most of the pages on this thread, entirely possible that I missed an important post...

I don't recall anyone suggesting that foam tire anything, any class go away...

When did anyone suggest 1/12 rubber replace 1/12 foam?

When did anyone suggest 1/10 WGT-R replace 1/10 WGT foam?

Is there not a place and time for both, should there be interest? I think the OP was asking about the possibility, the idea of trying rubber tires for 1/12 scale chassis.

If the very thought of considering rubber tires on 1/12 is cerebral overload for you, move on...
