Removing excess rubber debris

My semi slicks picked up so much rubber off the track at Winton this weekend that they feel way out of balance. Do I just keep driving till it all wears off or is there a better way?

The fastest way is to do a quick burnout.
That's how I cleaned the pickup from an old pair of ex-track tyres I had (granted, they weren't semis, but the concept is the same)
Just wet down a small patch under the tyres before doing it to help get it started.

Thanks for that.
Any other ways that don't involve possibly being unkind on someone else's drivetrain and which will also do the front tyres?

Good one Dann. Of course I could also take the trouble of swapping the wheels around, but you know how lazy I am.

A good hair dryer or heat gun and a wide paint scaper will get it off if the burnout method isn't convenient.

I have cut the biggest chunks off with a thin bladed cutting knife. Then track time to get them off, and swap the rears to the front and more track time to do them evenly.

It should just come off on its own.

I just drive the car and it comes off.

You say that like we all own hair driers...

This stuff is like bonded on as if it's part of the rubber of the tyre. Ripping it off also removes some of the underlying tyre rubber.
I will be trying the heat plus scraper method.

Hi all,
I have seen pit crews using hot air guns and a spatulas to remove pick up...
Something similar has been discussed here:

Well, I subsequently discovered the tyres were 10 years old and full softs (I should have checked before just using them). So no real surprises they were getting so soft on a hot day that they picked up so much debris, or that I got slower every lap and slower every session as the temps climbed and the debris build up increased. Lesson learned.
