Just got a 2 inch level on my 2014 f150 stx 4x4.. what's the biggest tire I can put on this bad boy. I found a good deal for 4 nitto terra grapplers (275/85/18) but I'm afraid they may be too big. Any thoughts? I'm running 275/65/18 right now abut they look like my truck skipped leg day..definitely need bigger shoes on her. Any input would be awesome.

That size tire will not fit with a 2" level unless you plan on cutting out your fenders. 275/85r18 is almost a 37" diameter tire. 35" would be the biggest, but still will require some trimming on the front plastic valence and something done with the back of the front wheel well liner. I have 1.5" lift up front and running 34"(285/75r17) and had to trim the valence and pull the back of the front wheel well liner back to clear lock to lock. I also have aftermarket wheels with 0 offset though.


You could go with a 285/70r18(Touch under 34"), 295/70r18(Little over 34"), 285/75r18(Just under 35"), or 305/70r18(Same height as 285/75, just a little wider)


As long as you are ok with a little trimming on plastic, 34's or 35's can fit. It comes down to if you want to go wider or stay a little narrower

I ran 295 70 18 Trail Grapplers on my last truck (2012) with an Autospring 2". Wheels had a +18mm offset and had zero rubbing. I also did a 3"rear block.

I'm running 325/65/18 which is 34x13x18 basically.

2.5" level in front. FX4.

Minor rub at full lock

So I made a mistake the tires are 285/75/18.. will it fit?

I also have 14 XL 4x4 and I fit 305/70r17's (34" tire) on mine. I know you have 18's but I'll bet you could fit the same. I had to do some minor trimming but nothing bad at all and no more rubbing.

Aftermarket rims?

+1 on the 34" I have 34" duractracs and they rubbed a little on the plastic mud flaps with a 2" level in the front and 3" block in the read. Without flaps a 35" would fit no problem. I can't see a 37" tire fitting without major modification.

Yea I messed up on the specs of the tire.. I meant to type 285/75/18

I think you will be okay on the height. I am unsure about the width.
