Anyone running these tires? These tires are on my short list, but I need to know what lift and backspacing I need. Most lifts mention 12.5", just wondering what I need to do to accommodate the extra 1" width.

I'm not adverse to going to flat fenders, but it seems this would be more an issue of backspacing than lift.

Anyone that is running a 13.5" tire, let me know what you've done and how it is working.
