Default Parma 12th scale tires

I noticed that parma offers black rears for 12th scale. Just a hypothesis, but would running black/black be similar to double pink/double pink from say jaco, or what combos have people been trying?

Parma's black fronts are used where their double pink fronts are causing traction rolling. Parma's black rears is their double pink. Black rears wear fast.
Stock: parma purple front/ black rear or jaco black wrap fronts/ yellow wrap rears
19T: parma purple fronts/ pink rears. I haven't tried wraps yet.

Blacks are in the same family as whites and grays. They are a little harder than a Gray. What I have found is the natural rubber tires (pink, dbl pink, purple) have more forward bite but less side bite. Where as less rubber tires (white, yellow, gray, black in order from soft to hard) have less forward bite but more side bite.

At the birds pretty much everyone in Stock ran dbl pink fronts/yellow rears that were using Jaco's. For Parmas I think they ran Purple fronts/gray rears. Same with CRC.

black,white wear out realy fast but the purple,pink dont.

and ya black,white wear faster cuz they side slide a bit and scrub speed i think

At my local track, I've been running the Parma tires on my Rev.4. Usually running Purple or Magenta fronts and Pink rears. I found that the Pinks have a bite very similar to Grey's, but wear a LOT better.

If you run Parma rear tires pick up 2 bags of rear axles shims..you will need them. They have a diffrent offset than Jacos and you will need to shim your axles a ton to get your rear track back to 172mm.

You can try cutting down the amount of axle shims you use, by using a glow plug shim or two. I use some used traxxas glow plug shims to shim the rear axle on my 12l4 when using Parma tires.

I have never had this happened. How long are you letting the glue dry before putting on traction compound?

I have heard of this happening, and it was due to letting the tires soak in paragon in a zip-lock bag for a week to soften them up. It seems too much traction compound maybe not necessary.
