Here's my thaught about how you hook your car up with rubber tires.
Win running rubber make sure the front tires are harder than the rear, also what brand and shore is important. Here are the different tires that work, Yokomo, Sorex, Proline.
Depending on the track condition dictate the shore that should be used, I perfer Yokomo 36r's and lower when racing parking lot.
If you notice that your car is hooked at one track and not at another, don't change your setup change your tire. This goe's for foam and rubber.
