I was never a Modified TC racer , but if the new tires were holding That good ( 1mm in 15 runs) thats not bad performance. Except for VTA and GT ,I think I would like to try stock Foam sedan again. For Me It could be a new start for TC

Are they allowing saucing? How long can you use them legally(to what diameter)?

I may have a silly question here.... if the tires are coming pre trued to a set size and there is going to be a minimum tire size, why not use larger diameter wheels so that once you hit that minimum size the foam is pretty much gone. Or does that not make sense. When I started with touring cars we ran rubber (hpi rs4 days) foams came after that once carpet became more popular.

The smartest post made in this thread . unfortunately unless the wheel demand (sales ) can support a redesign of the mold to make the wheels it will not be worth the risk. I would guess if this was to catch on that would be the new spec tire combo.... Maybe price could drop a bit more once they started selling more

There is a max wheel size in ROAR. Not that this is a ROAR class but if it ever is that would prevent it.

I ordered a set. I’ve got basically zero experience with foam tires, and probably not great surfaces for them. But figured give them a shot.

Watching Paul and Keven rip around looks fun, but watching everyone else destroy themselves makes me think for the better of everyone going backwards in time is just going backwards
run your rubber tires with out glue. and even if we trued them to 57mm we could still get 3+ runs out of them. We ran these this way as a test, and in the most extreme conditions. Tweaking may be necessary, again lets see you run your rubber tire car without glue, I bet it flips just as easy.

Rick, I have never seen as violent traction rolls as with rubber tires. Foam rolling is so much easier to control, IMO. The reason for the faster times, cars are more planted and easier to drive, same HP as rubber, but you know that.
When I owned my track, we lost a lot of new racers once we went rubber. They couldn't drive the cars as well as the foam.

here's another reason IMHO
Mod Foam 10.8
Stock Foam 11.9

Mod rubber 12.0
Stock Rubber 12.3

There is no point in even putting Mod rubber on our carpet tracks in the US.

Foam FTW.

Again 1/12 longest running class. FOAM.

It works. K.I.S.S.

Or if you’d rather, all the rubber tire guys come up with a rubber tire
that can compete with a foam tire at a decent price point. I’ll buy it... haven’t seen it yet.

I just went and looked at the price for these. $21, get 15 runs at least with mod... Better handling car and more predictable, or should be. I am going to pitch this to the guys at my track, see if we can switch... Or at least try it out.

I'll run these when they stay the same diameter for the life of the tire and don't chunk.

Cut them down to begin with and they will never chunk.

This is like standing up in class after the teacher asks someone else a question and going "I don't know but I think that was stupid."

So basically people are complaining about glueing the side and the traction rolls... So we are going for low-profile foam tyres... Why can't the sauce just be forbidden? Or limited to light-effect ones?

CRC carpet should be perfect for that...
