What is the biggest tire that cab fit on these new trucks with NO RUBBING at all? Looking a picking up a new 2017 f250 and want to put some bigger tires on it

 

anyone have information on this?

 

Its pretty much the same as previous years, the biggest on a stock truck would be 295/65R20 or 18 depending on wheel size. Lots of guys run that size with no rubbing or issues at all and it seems to fill in the fenders a better.

The taller stance on 2017's is just a body lift, not suspension. If you want to run larger tires you have to get a suspension lift.

Well, I ran a 35x12.5x18 on my 2016 King Ranch on stock rims. No rubbing or issues. But yeah, this is an old post, so he is probably all set.

 

I have 35x12.5 on stock 18" wheels with no issues at all.

 

Are you guys running 2017 or older trucks?

How do you use them, on-road only or off too?

Are your trucks leveled or bone stock?

 

Regarding your question about usage, my truck is used for commuting, hauling, towing, and off-road. My last truck (2016) was a bone stock F-250 diesel but I installed the 35" BFG KO2 tires I mentioned. A lot of my jobs involve getting up fire roads or logging access roads to a site. Extra clearance from larger tires is always appreciated. Nevertheless, last fall I was in my 2017 dually - bone stock - and handled all my job site needs. 4x4 was a must, and I scraped something under the truck once...but the dually has relatively small 31.5" tires on it.

 

Is that an 8" rim??

That's a lot of tire on an 8" rim. A lot of tire.

 

That's what I had. It is a lot of tire, and I remember BFG saying the minimum rim width was 8.5" and the Ford rims are 8". The tire shop told me I could take the risk if I wanted (I did) but they would not be liable for problems. I had no problems.

 

I had a Bronco that I had Mud Tires on, 33X12.50 - 15 back in the day. I didn't go looking for mud but if got between me and my campsite (about 99% of the time), I had to get through it.

Then there were times when Bud(weiser) and I would go take on the mud for S's and G's. I usually won.

I had a winch on it but every time I got stuck, there was nothing to tie off of. I never could pound a 'dead man' in far enough to make it work. And I'd rather have a root canal than mess with a Jeep Jack.

So I started carrying a Danforth Anchor with me. In the back. It rattled like Heck so I taped it up with Duck Tape

When I got stuck, I'd take the anchor out as far as I could and try to get it started on hooking up before I cranked up the winch.

It worked. Every time. Not always the first time, but every time. I even pulled a big Swamp Buggy out with my Bronco one time. I was a Hero that day. Nothing to tie off of (If you don't anchor your rear end down somehow, all you do is pull your own truck) so I took the anchor and tied it off my rear hitch and started pulling. That Bronco was dancing like it was wearing a bikini and on a pole.

Got it out.

Where was I?? Oh yeah. I ran those 12.50s with an 8" rim until I found a deal on some 10" rims. What a difference they made. Laid that tire tread down much flatter.

But that was then. Back when the Chinese were first starting to enter the market and they were giving stuff away at cost. I'm sure that new rims now would be a fortune. Have to sell body parts.

Good luck. I'm sure you'll be fine

 

Did you trim at all? I saw a video where someone put 35" tires and they were millimeters from rubbing against the inner fenders on a stock (no level) '17 F250.

I'm thinking of Open Country MT's in 295/65R20 on factory wheels. Its really not much of a difference from the stock tire, but I don't want to run a bigger tire on that narrow rim.

 

Stock tires on the 20" Wheel options are 34" tall 275/65 - 20

275mm divided by 25.4 (mm in an inch)= 10.8 inches -- That's your section width -- The widest part of the tire. Then you take the aspect ratio times that for the height of the sidewall -- In this case, 65% of the width. Some are 70, 65, 75, 80, 60, 55, etc ad nauseum

So you multiply that out times the aspect ratio of 65(%) = 7.03" X 2 (two sides vertically) = 14'' + the 20" rim = 34" tall

Confused yet? Yeah, I'm not the best explainer in the world so don't feel bad

 

No trimming for me...I have no interest is cutting up a new truck. Never had any issues with the 35x12.5 tires all stock setup.

 

Those are are 18" or 20" factory wheels? Which wheels do you have?
