Well by time im done with this it should drive up the steep hill at smiley's house without much issues. I hope anyways lol.
so far this is my first mod. this thing will start now without spinning the tires no matter what surface it is on. Havent tried sand though but gravel/road/blacktop/grass doesnt spin at all. I only put the tread on the drive wheels (yes this is rear wheel drive).
This first picture shows the tread with the sidewalls cut off. The tires actually came from Skylers bike because he was riding around on flat tires (I didnt know it) so he ruined the tires and the inner tube. It doesnt look like he ruined the rims so I am just gonna buy new tires/tubes for his bike.
This next one shows the difference with having one tire with the tread and one without.
