Solved Resizing in blender

So a while back i Built custom rims in blender only to find they were much too big. Can someone please help me scale them down to something usable in game and show me how to properly install them for a 6 or 8 lug hub in game.
This is what i have so far (sorry for the dual screen and weird screenshot i couldnt figure out how to get a good picture in here)

 

cant help with much more, but 'S' will let you resize it. Also S+X to scale it by the X axis, S+Y to scale it by the Y axis, and S+Z to scale it by the Z axis,

 

also make sure to do CTRL + A to apply location, rotation, and scale so that it doesnt spawn in the wrong position in game

 

the origin is already centered but yes. that'd be something to do. mainly with scale.

 

Is there any way to tell exactly how large itll be in game by inches or centimeters because i want a somewhat specific size for diameter and width

 

thats beyond my blender skill, sorry

 

I believe distances in BeamNG are in meters. [citation needed]
You can set Blender's scale to meters here:

 

rims are inches.
