AreCee, he said side wall not inside wall...
Gluing the outside
wall of the front tires will help to reduce sidewall roll-under.
What happens on high bite tracks like seasoned carpet is that when the car approaches mid corner, the car has scrubbed off enough speed that the front tires will get more bite thus causing the sidewalls to roll inward with respect to the rim and will cause the rim to act like a plow. No more understeer and woops, the inertia of the car at the inside of the turn wants to pass the outside. Your problem is probably more tire related than setup.
Like I said in an earlier reply, tuning down the dual rate on your radio can also help. If the front tires are at a high angle when turning, understeer will be induced until the car slows down and then the car will experience massive oversteer causing the car to virtually stop via the leading front tire. Over she goes...
A stiffer tire with a stiffer insert will help but obviously, if too stiff, you'll understeer all over the place.
I hope I'm helping here.
Perhaps some of the other guys can back me up on this?
By the way, you should have many sets of tires to try when experimenting on an unfamiliar track surface. Perhaps at least 3, soft, medium, and firm so that you can have something to compare to. Try to avoid using old tires all together since you will not have a direct comparison to different compounds. The sidewalls go through a lot of abuse and become too compliant thus causing them to roll under easier than normal.
