Fronts no problem. Rears are a different story. Get rid of quad shocks and should be fine.

If I’m not making sense then ignore me, totally plastered at a bar while working out of town but I know 315’s are sexy and work fine with no quads. Quads are for pussys and don’t help you.

315's will fit if you ditch the quad shocks. If your stock lower control arm bushings are worn they might rub the inside of the fenderwell on turns.

Hold your head up blak. My wheels and tires rubbed the quads. I also have MM HD lower control arms so the quads aren't needed.

I had to reverse my quads! Took about 5 minutes each & they don't rub now....I too have the MM LCA'S adjustables though....I love the staggered 275/315 looks!

have 315's on mine with quads, no issue. it will depend on the offset of the wheel. you might even be able to get away with a small spacer to make it work.

I can say, I have replaced my quads with new ones. I could tell a definite difference with the new ones on...tighter. I figure the engineers at Ford know more than I do, so I will retain them until or unless there is a better reason to remove.

Had at least 6talls at Texas Roadhouse with dinner. Then we walked to Bar Louie and I had a $150 tab. I don’t remember texting or posting that night but from seeing what you quoted I’d say the evidence proves otherwise!!!! Lol

But my answer stays as is, 315’s with no quads or go home!!!! :)

They are criticized but I run Sumitomos in those sizes & get 25K or so out of them...Even in the rain here in Oregon they have done well gripping the road. I do really slow down a lot if I get caught in rain as the wide ones can float easy...in the dry they grip very well for me until 3 years or so then they harden and get slicker....I love that cause I can burn them up & not feel bad! LOL, cheap to replace!

I will try the Nittos someday or another premium someday just to compare.

I used to run the Sumitomos but found, at least, down here...horrible in the rain.
