What tyre insert do you guy run?
 

I noticed my rear tyres getting bald patches in middle of tyres, not full coverage across, so that mean im running too hard insert... I'm running medium foam insert....

What do you guys run?

many thanks.

I run Schmacher Tubby's. I think you'll find your getting that thin line due to the fact that that part of the tyre is the part always in contact with the surface as your camber changes through the corner.

I just use old medium foams that I've removed from minispikes, the carcass of minipins is stiff enough that I don't think the foam makes as much difference as on other tyres.
As long as the car handles fine I wouldn't worry how the tyre wears.

I run Answer RC foam inserts; same as Schumacher, just cheaper:
