35's on 2008 4X4 F150/MarkLT

I’ve got a 4X4 MarkLT (same as F150 except Lincoln) with factory 20x8.5 inch, 6x135 bolt pattern 44mm Offset rims, added 2" leveling kit.

Looking to put 35X12.50R20LT Toyo Open country M/T on these rims.
I've run them through the online calculators and tried to measure the fitment on the truck but hard to get accurate measurement.

I know these types of questions have been asked before (I've done a search) but couldn't find an exact answer.
1. Will I have any rubbing on suspension, frame, wheel well etc.
a. If rubbing where.
2. Would love to see pictures of your rides on 35's with 2" leveling kit.

Howdy thar ...

Yeah - they'll likely rub - on the suspension components with the stock wheel - which is why some folks run spacers - which I never recommend - new wheels with a different offset/backspacing are safer, albeit costlier.

May even require some trimming in the wheel well - won't know until you go lock-lock and full suspension travel extremes.

You risk a couple thangs here apart from rubbing:

- level kit stresses ball joints / suspension components needlessly
- 4R75 is stressed - again needleslly, unless you also invest in regearing
- truck is gonna be a dawg ( increases in static weight and rotational inertia, rolling resistance, and effective gearing alteration )
- speedo will be off
- shift points will be off
- braking distances will increase
- weight increase affects damping
- weight increase affects spring rate
- noticed the S&B - yer likely running lean already - need a custom programmer to fix that - which will also hep with torque, GR/TS correction. WAI offers no gains without tuning - and very little with ( but at least tuning renders them safe to use on a x.xL 3V with a slot-style MAF, if you simply MUST have the bling under the hood )

Honestly - all of that added overhead for a little different look? Reliaibility takes a shot to the head? Perf takes another one in the nutsak? Mileage vacates the building? Seriously?

Mods need to be planned and executed systemically and holistically - something 99.9% of you youngin's don't do....

Yer truck - yer money but there is nothing even CLOSE to a net positive result here, in my view.

In any case - good luck. Lots of OTHER youngin's here whut will happily ignore the realities and step up to hep yalls. Hey - after all, they be youngins, aight? Yalls gotta LOOK GOOD and pooker everthang else! It's what they DO!

Oh - an' there be LOTS o' pitchers o' ED Zachary the same setup as yall wanna run on here - 'cause it's as common as hillybillys at a female mud-wrasslin' an' beer-swillin' contest.

Well hellfahr - I did yall a quickie search - here's one thread: https://www.f150online.com/forums/20...cs-please.html



PS - if'n yall take me all serious-like, I cain't be held responsible fer yer migraine

295/60/20 is pretty much the biggest size you can run on a stock wheel without serious rubbing issues, and even those are best with a 1/4" spacer. They look better than 35s IMO though.

The problem with the OEM 20 inch wheels is they have a lot of backspacing. This causes some 12.50 inch wide tires (33's or 35's) to actually contact the upper control arm/ball joint. Usually it's 12.50 inch wide tires with aggressive sidewalls. The usual solution is to just run a narrower 33 or 35 inch tire (like a 285mm or 295mm width).

like others have said above, you will rub, and pretty good with that tire and wheel. i ran 33x12.5 on my fx4 wheels and i rubbed on the a arm and i had a 2 inch level.

you need wheel spacers/different wheels/narrower/shorter tires

and performance is gunna suck with 35s

My aftermarket wheels that are 20x9 +18 offset, would rub with the 35x12.5s, with the side lugs, those tires are technically 13"s wide. I had bought a set of 35 and it would not have worked on my truck, works on '09+ due to better UCA clearance. Would need a -12 offset to fit them, and even then without a full suspension would require trimming.

Highly will push you for the 295/60-R20 Trail Grapplers, a great size and fitment, 1/4" spacers won't hurt things for added clearance.

I can't believe I'm saying this, but I disagree with Darren on this one. I wouldn't put anything at all on the back-side o' me wheels. But that's just me.
