Just a quick chime in. I tested and tuned 4 total TA cars for the big race weeks leading up to the race. Just so people know who might be following these posts for tech info....just slapping the specified TA tires on the chassis isn't where you stop with tires before moving on to other tuning options.
Here's what I found out with the tires:
New out of the box they need to be sanded slightly or have quite a few runs before they "stabilize"
Keep your tires clean for every run.
Choice of traction compound makes a big difference on carpet or concrete.
How you apply the compound makes a big difference.
Camber can have drastic effects for anyone who is an average racer and above. Same with toe-in.
A little bit of CA of the sidewalls can be very helpful if you are expereincing traction rolling issues.
My point:
After slapping on TA tires go thru the above checklist and make changes to those points first before you move to chassis or suspension changes to adjust handling because the above items can drastically effect handling on carpet and concrete surfaced tracks.
