Unsolved Stuck with Mod, not sure where to go

The mod I'm working on is for a playable Mario Kart in BeamNG. The vehicle wouldn't load (fixed), and I'm confused on where to go from here. Can I get a little assistance?

 

packaged wrong.

also an error in the main jbeam i cant fix

 

kart_tires.jbeam is missing a trailing }

 

wait a sec isnt this the same thing as what @SushiPro made?

 

@Alex_Farmer557 I don't think so. This is a Mario Kart 8 Standard Kart mod.

Next question: Why isn't the kart making the proper sounds?
I have an SBeam with the sounds in the sounds folder
Also, how do tires work? I've always been confused on how to make the tires and how I place them in a vehicle.
