Here's a thought...keep your stock rims, get a set of 1.5" wheel adapters, and run some 255/85/16 tires. It's hard to describe what it'll look like, but if you've ever seen some of the smaller armored vehicles with the wide-set, tall & narrow tires, it's about like that. The 1.5 adapters should put those tires just barely at the outside of your fender flares. Pretty much any tall tire with an 85% aspect ratio will look that way, once you get to 37x12.5 it looks about right...tho on a 10" wide rim with a wide tire it starts looking like an overgrown moon buggy
.
If you have the small, thin moulding, no holes. If you have the big flares, the ones that are a couple inches wide and tall, there are holes all along the fender.
