I've run the Exotek rims on my F1R and I like them. They are easier to glue up and while they might not be quite as flexible as the Tamiya rims (the ones for foam tyres), they are far less brittle than the Ride rubber rims, which crack very easily.

Just gotta dial some "laziness" out of my chassis

They are not the same compound for sure. The Rear TCS are slightly harder and seem to have more rubber in them, they dont scrub in the same and Paragon effect them differently. On our prepped asphalt track the 571's are quicker and on our parking lot track the TCS rears are faster. The TCS tires absorb compound while the PIT compounds keep the compound on top and you have to wipe it off.

Take a look at the pics of the cars and just scale them so they look right to you.
Here's a neat chart Lightfoot put on the Vintage F1 forum and you can see most of the meatballs (white circles) go pretty much the height of the body. Some are even flattened on the top and bottom.
Thanks I thought I was going nuts. Which I may still be, but at least I know that I didn't make that up.

I run the TCS and Pit tires on our carpet and asphalt tracks and notice no difference between them and have been told they are identical.
Your results are interesting with the tire compound.
I use mainly Buggy Grip and Tire Tweak and the tires work equally great for me.

Are you using black can or white can Paragon?

I think they are the same compound. And I don't find the differences when traction compound is applied to be true.

I've used both the black and white can Paragon on both TCS and Pit tires. On all my rubber tires, the black can tended to "soak" in while the white can was still very drippy.
Didn't matter if it was Pit or TCS tires. Same with my touring car tires.

Marcus is definitely our resident tire tester!! he's using black can Paragon.

and you guys might forget, we're down here in Texas, heat and humidity are high!!

I am positive they are different, Take a brand new set of both and run them for 10 min and you will see that the 571 show a very strange wear pattern where as the TCS look more like a normal scrubbed in tire. On our big track the 571's are consistently 2 tenths quicker back to back . And i am only referring to the rear tires I didnt care for the TCS fronts at all. Think about it its TAMIYA we are talking about and they dont leave anything as is you can bet they added their "touch" to the compound. Why else would the 571/572's even still be on the market?? That wouldnt be a smart business move for PIT. Maybe the weather conditions here in TX magnify it but they are not the same. IMO the TCS rears a med compound, in a 10min main on a track with temps around 140 they go away quicker than the 571's. Trust me when i say i have tested them ALOT!!

I have been ultra-busy lately and have had a delay on the F2012 style wing vinylís, same goes with the FGX, I do have wings to test on.

Let me know about any special color requests. can always paint them and apply to get an exact match.
Anyone know what red best matches the vinyl used in the Traut wing vinyls?

In regard to the nylon of the Exotek wheels, I recall "back in the day" that we boiled Associated nylon parts to make them more flexible. Think this might work with the Exotek wheels?

Indeed. The same compound was specified

Since everyone is talking about tires, has anyone tried these?

As previously stated, the TCS tires are the same tires from Pit. The only change Tamiya made was adding the TCS logo to the side wall for an easy tech inspection. I'm 100% sure of that.

Now, Tamiya ordered the tires roughly two years agoÖis it possible that Pit has changed their compound in the mean time? Maybe they developed a faster tire and left the Tamiya tires as isÖusing an older formula.

Keeping two different compounds for manufacturing may not be cost effective unless one material is much cheaper than the other. Pit shimizu tire prices stayed the same so the material cost must be pretty close. (If they indeed change the compound)
