I got American Eagle Wheels Series 178's size 18x9 for my VX. You need some wider tires for them, though. I went with 285/60/18s and trimmed my cladding (a lot). You could probably go with 285/55 or 285/50 and have little to no trimming though.

They're cheap, give you that bulldog stance, and look great!

I got them in polished alum. finish cause I like that look with the VX, but chrome would be a lot easier to maintain (obviously).

Good look for a tonka VX might be to powdercoat them yellow or black.
