I made spike tires for my Hiroda buggy. Now I can go on ice and compact snow .
Its basically for the rear tires 3 row of 24 clip board pins, glued with cupper silicone ( I used the remaining silicone used to fix my real car). I have about 1/4 in long metal spike that go out of the tire. I decide to glue inside the foam to the internal wall with the pins heads, and I didn’t drill breading holes in the rim, I want to prevent over stretching of the tire at high rpm, with the quantity of spike inside , it’s a additional weigh of 32g per wheel. The front spike tire, with 2 doubles row of 22 pins for a total of 88 pins per tires.
