[BWRC_6M]

what is the best disc to use we run on the WRS2 tire which is really hard and kinda feels like plastic

80 grit sand disk at low speed. don't wont to heat the tire or make any smoke.

I typically used 36 grit sanding pads.

I use a Makita 4 1/2 grinder that is variable speed $159.00 its the smaller grinder not the huge polisher and its variable speed!!!!! I use a 36 grit disc as well you have to get the conversion backing pad, it can stand the abuse and its light and you can run it slow!!
