Thanks! This is all good info. This is the productive side of internet forums and I am glad to see you all chip in with good info.

I am really impressed to see that someone actually knows about the different types of manufacturing processes for creating foam tires. This has always been a therory of mine, but I just did not do the research to prove it. While a Parma rear pink has the same durometer reading as a grey, they obvisously have different traction and wear characteristics. I too, have a tire durometer that shows these two types to be about 28-29 points. The pinks push and change, the greys are balanced but wore fast (for me).

I too have found that the Jaco pink/double pink combo is pretty much a handful for the opening laps and then settles down for the remainder.

I sauce my tires for about 12-15 minutes with TQ Mod and wipe fairly dry with a fresh paper towel. I clean the tires off with motor spray after each run to remove the build up.

For what it's worth... in the old days, I recall that we all used Jaco grey/purples. The greys always wore about 2:1 to the fronts. If you were "cool", you would own two sets of grey rears for each set of fronts and rotate the rears out every few runs. That way you could keep your split from getting away from you. But we are running a lot faster now a days and on different carpet with different traction sauces.


I like Eric's advice the best: stay with the same "family" of tire and fine tune the balance. I never have liked mixing manufacturers together.

Eric; it's possible that we have crossed paths. But I often like to cloud my memory with a few local micro brews!
