IMCA Hobby Stock Tire Problems

It sounds like the tire has too much rubber and too many edges. Probably think i'm crazy but alot of the kart guys get new tires and put them on a tire lathe and turn them down. Here is a link to a guy cutting some rubber off. https://www.youtube.com/watch?v=GAasIWzUJaU

I think the kart guys use a bondo grater/rasp.

I ran the radial GT but I also ran 275/60/15 not sure if they have them in your size.
