Again, I don't know why our tires would be more prone to peeling than any other. We simply don't see it. If they do, we warranty them. If they chunk, we don't.
A double pink front would make the steering too aggressive even with a pink rear on the back. The orange "smooths" out the car's response and makes it less twitchy. We grade the tires as follows: Pink-30, Double pink-35, Purple-40, Double purple-45. All these tires are in the same "family", although performance is quite different.

If they come unglued (not rip) we will replace them. Look carefully. If there is white rim showing, then it came unglued. If you see black, then the tire ripped from impact.

Default shore rating

Jack, You gave the shore ratings for the pink-purple categories, would you happen to know the others? white, grey, plaid etc. Nitro racing tires are far easier to figure out using shore instead of colors!
Thx

Jack thanks for your reply, next quick question.

I ordered double pink and pinks. Instead of double pink/orange for fronts. How different will the car react running double pink/orange in front and a double pink rear or pink rear. Since I'll have some pinks that looks like I didn't need.

Thanks...

Hi Jack, sorry I missed your post...

I've never seen white rim, so I guess they rip. I have much less trouble with Parma foams ripping.

As far as fit, I like the offset in the Parma foams. Jacos tend to rub on the shock collars when I run them. I have taken to using an xacto knife while the tire is on the lathe and taking off a millimeter from the inside of the tire to reduce this.

Performance-wise, the Jacos do seem somewhat smoother than Parmas, but seem to wear much more unevenly. Not sure why this is, but when running Jacos, I always get a couple tires than cone pretty badly. With Parmas this doesn't occur so severely.

Isn't almost the entire Xray team sponsored by Jaco?

since we switched to Parma we haven't felt the need to go back to Jaco's. the wraps kinda interest us but hearing mixed results on the tracks we race on so we'll stay with Parma.

double pinks = Magenta, double pink/orange = Cyan.

As far as the Jaco/parma 1/12th scale foams go; there is a lot of difference between the two. In general, the parma foam is softer, and tends to be a bit better in low grip conditions. For example, a parma pink rear is different to a jaco pink rear; you can feel the difference with your fingers.

However, using jaco greys/purples back to back with parma greys/purples will give pretty similar (although not identical) results.

I would assume the same goes for the 1/10th scale foams too
