The rubber tires that weigh close to foams, and hook up the same are the Sorex JB rubber tires, either 28 shore or 32shore... They can weigh as much as 38grams less than other brands of tires, and the tc4 loves them... They are a little more expensive than the other brands though...

I switched back to rubber and adjusted my setup and managed 3rd overall. I was super stoked though This car was built for foams and my car came ALIVE with them. If I find rubber that will hook as hard as foam ill be dangerous
