Which shore rating you use depends on how much traction is available. If traction is low I would suggest using a soft shore tire like cyan front and tan rear (TRC tires) the Cyan is a 37/45 and the tan is 37.

As traction goes up move up to a harder tire. Like plaids and purples 40/45 and 40.

Also glue the outside edge of the foam on the front if the car turns in too hard and wants to traction roll.

Just my opinion.

Orange Purple(plaid) and Purple or Orange d.pink and d. pink.

Definately use compound, paragon works well. I used some corally tc3 compound on the weekend and it seems to work well to.

Definitely try plaids in the front and purples in the rear as a starting point. Sauce the rear tires fully with a traction compound like Corally's Jack the Gripper, Paragon, or TQ Blue or TQ Orange. Sauce the inside 1/3 of the front tires as well. Let it sit for about 10 minutes and then wipe the tires off before you hit the track.

If the car is still too loose, you can try going to a softer rear tire, like the aforementioned tan. If you want to stay equal on both ends for more bite, try cyan fronts and tan rears.

Foam tires are set by a shore rating, where, for example:

Orange: 45
Purple: 40
Tan: 37

When you look at a "Plaid" tire, it has the outer 1/3 edge of the tire in a harder foam (orange) and the inner 2/3 in a softer foam (purple). Same for Cyans. This stops the outer edge of the tire from biting in too hard in the corners.

If your car is traction rolling, you may also try putting a bead of CA glue along the very outer edge of your foam tires -- this practice is pretty standard at high bite tracks.

You may also pick up the latest issue of Xtreme R/C (#101) for my article on foam tire versus rubber tire setups, which covers some other basic things to try when running a foam car.

Good luck!
