Will rubber carpet overtake Foam carpet in the future???

So after a few runs the tire is significantly softer from the rubber being broken down making a worn out tire have more traction. This is a little different though on low traction, but that's not what we're talking about. But it is true gluing the sidewalls will take away side bite. But a fresh set of tires will always traction roll less than a used set.

as far as more traction as a tire gets old goes...
im no chemist or material scientist so i cant tell how this works chemically...
but more traction as the tire breaksdown and gets softer only applies in an ideal situation where the tires material makeup and chemical structure stays the same. this is not the case as the tire goes through heat cycles the actual rubber compound goes through changes due to the heat cycles... i mainly have experience running sorex 36r's on high traction asphalt and what is seems is that as the tire gets more cycles it does get softer overall and loses sidewall stiffness but the rubber loses its "stickiness" i.e. after the first run using paragon you can pull the car off the track and the tires are very sticky... but on an old set say 15+ runs you can pull the car off the track and the tires come off almost dry and not much tack...

I love rubber and asphalt. To keep the tires useful you have to manage them correctly. Obviously I practice on my old sets and keep my new ones for the races. If you prepare them by using a tire sander before each run and clean them down after with parts cleaner, they come out pretty new.

This all opinions and perceptions. Where I race the sportsman (novice) stock and stock classes went to rubber tires on carpet. So I don't race TC any more, I hate the idea of deevolving a class or classes in the name of a false economics move. Now, before the haters start, I tryed it and broke more parts and peaces after buying more parts to set up the car for the softer set up for rubber than I ever did running foams in a season. The result one less racer and less support for the local track. Why should I spend MY money to race and support a track that doesn't care.

Maybe if you talked to your local track about running foam tire they would let you. Here, if we have 4-5 guys running something, you have a class, and are more then welcome to race. Instead of tearing the place down, try being civil about it and Im betting you'll come up with something.

Hi all
What bodies are you guys using with rubber on carpet?
All I see is Mazda 6

The only thing foams are good for are Tire Inserts, pan-cars and Factory Drivers.
On a club level there is really no room for foam, you chunk-it you junk-it has been my slogan for foams.
Plus people who say foams last a long time, what do you say to those who true theirs down to the rim to make their cars handle better. . .

Chunks glue back in, I have done it many times. Even if you can't find the piece, you can cut one in from an old tire.
Again, if you want to go fast, you can true the tires down. If you want to go fast in rubber, you will put on a new set every 5 runs (every race day). There is no difference. Speed = $$$

Killer Packs + 140 degree track temp + 95 degree ambient temp + 5.5 final drive = magic smoke released from motor.
It sure was fast for 4 minutes though....
