There used to be a concrete oval near in my home town that was a scale layout of Talledega. So I guess it wasnt oval but it was definitely an LTO track. Anyway they ran pan cars back in the day with tires that were foam core and rubber on the outer layer. It was like they had a piece of bicycle innertube glued to the outside of a foam tire. I was wondering why current rubber tires arent made this way. You would think that it would give you a more customizable contact patch with less sidewall flex compared to a current Jaco or similar rubber TC tire.
There must be a reason they arent done like this anymore. Maybe its just that something else outperformed them.
I was hoping someone in the industry would be able to answer, or at least someone who raced onroad during the transition from pan car to TC.
