Rubber/Latex Tyres for Tyco 440X2's wheels

My next experiment will be a very soft compound made out of latex and the hard rubber I'm currently using to cast 440X2 tyres.

Latex needs a lot of time to cure at room temperature but the compound will be a lot softer than hard rubber's compound I use now.
   If real world's idea works in Ho slot car world too, softer compound will mean better handling and performances but reduced durability !!

The biggest question about this new compound is related to the latex shrinkage. I hope hard rubber compound will compensate this latex property.

Silicon Tyres for Tyco 440X2's wheels

There are a lot of very good silicon tyres manufacturers so I don't know if I'll start a little production of silicon tyres.
