Default Foam vs. Rubber

I'm going to start racing indoor carpet soon. I used the search function and found a few threads on this topic but not many.

I'm going to be racing 17.5 Touring Car and 13.5 1/12th. I obviously will have to use foam on the 1/12th and have heard I will need to get a truer. So if I get truer... then that sort of makes it hard to decided on if I should run rubber or foam on the touring car.

I'm a college student so money is definatly an issue. The carpet track is only a couple minutes from campus... so I will be at the track practicing all the time. So which ever tires I use will get used a lot.
Please let me know what your guys opinions on the topic of Foam vs. rubber and which you think I should decide to use.

Thanks,
Ethan

if youre tight on money then you'll probably want to run rubber. they will last a lot longer, but if its a mixed class of foam/rubber you could try and ask others for their chunked tires they dont use anymore since you'll have a truer anyways!

Foam is for seat cushions and insoles.

I dont know if you should even bother getting a tire truer. I have had one for acouple of years now, and have only used it when I mount donuts. If you are buying tire/wheel combos that are ready to run (like CRC's), then you shouldnt need to true them.

Before everyone jumps on me for this one though, I do know that smaller diameter wheels/tires work better then full size, but for club racing it should not make a difference.

Besides, your local club may already have a truer members can use, or just ask another racer.

Run rubber on the TC. They will last longer, and it takes some of the variables out of running a class that's already WAY TOO COMPLICATED. Plus if you run rubber there's a wealth of set-up info available for virtually every chassis on the market.

I still prefer TC's on FOAMS, but I'm definitely in the minority at this point.

+1.

Foam is 10 times easier to drive than rubber, but rubber is 10 times easier to get a consistent setup on than foam.

I doubt your club even allows foam in TC. Very few do these days. So if you think you want to run foam, better make sure it's allowed first.

If you plan to run at CORRC, we don't disallow foams on sedans, but I haven't seen anybody run them at our track in years. Rubber tires (Solaris Medium, available at the track) have been the choice for a long while now.

That said, a rubber tire sedan can be a finicky thing to setup and drive since there's limited grip. If you wanted to throw foams on to practice, or just get the hang of things, I don't think anybody would mind. Like others said, though, foams won't last nearly as long. For practice, you can pretty much run the rubber tires until they fall apart.

Well in that case, the right foam tire on a properly set-up car is usually going to be faster.

Foam tc is a much better race then rubber.. Cars are closer less penalty for a rub, nudge or push... Even less on a wall touch... Money game is the same run what your local track runs. And from what I can see foam is on the rise across the board at club level.

Maybe in the mid west, where foam got started, every where else it's dead.

Those rubs, nudges, wall touches or pushes usually resulted in a chunked tire.
