Ordered the Wildpeaks today at Discount. Spoke with the store manager and he said they may have a slight rub but most likely they should fit with no rub. Get them installed on Thursday.I can't help you with the Falken Wildpeaks but I'm running Cooper Discoverer AT3 XLT's on my Pro 4X. Size 275-70-18. Just a little bit of trimming the plastic mud flaps. Very quiet and I'm getting excellent wear out of them.
