Hello guys.
So our indoor season is starting up. We race on a hard packed track. Usually dusty/low bite.
I got some new Dirt Webs in Gold and J Concept medium inserts.
The guys at the track were saying that its too firm of a tire to get any traction. I went to practice and the rear was on ice.
Once tires are glued , is there any way to disassemble them to remove the insert and modify it and then replace it? Or once glued, its done?
What do you guys do to modify the insert for indoor tracks with low bite?
Also, when do open cell inserts work in rear buggy (22 2.0) tires? I always choose closed cell foam. Don't know what the diff. between the two are handling/weather wise.

Thanks
Tom
