Hi Jody:
What is the exact size of your tires that you currently have on your VX? They seem to fit really nice inside the wheel wells (especially the front) without being lifted.
I too am looking to put new tires on my VX, and am leaning towards the BFG Rugged Trail TA (P275/70R18), or General Grabber AT2 (P265/70R18 or P275/65R18), or the Pro-Comp A/T (P285/60R18). All in "P" series for reduced unsprung weight. No way am I putting on "LT" series, as they're way too heavy to stop during braking. Riff Raff
