So I'm adding a wheel and tire pkg to my 2016 FX-4. I have a 2.5" PRO COMP leveling kit and I have been told very different things from two different tire shops. One shop said I can easily fit 35's and the other shop is saying 33's....305/65/18.


Im looking to add BFG Ko2's on Mayhem Missle wheels...


SO what fits...and do I need a tuner for bigger tire size???

 

I have 305's on mine leveled. Not sure about a 315

It's right on the website. Says "Fits up to 35 tire".

 

I'm assuming your truck has the front crash bars which is one of the big problem areas in regards to rubbing. I went with 295/60/20 on my 2015 Supercrew, and I have a 2.5" RC leveling kit. The tires rubbed the front crash bar. My tire is slightly taller than a 33" tire, but not as wide. I ended up spreading the crash bars with a hydraulic spreader just a bit and that fixed the problem. My wheels are a +1 offset. If you're going with an 18" wheel / tire, I'm assuming you will have a little more room to work with.
