Planning to upgrade your stock F250 with 35s on stock 20” wheels and a lift kit or spacers? Wondering if it fits without fender trimming? Curious about common setups among F250 owners running 35s with a leveling kit?
The above is possible all depending on your choice of tire and that you are running the stock OEM wheels/rims. There shouldn’t be any rub on radius arms or the sway bar regardless of lift or level, and neither should it touch the body anywhere when running factory offset wheels/rims.

Fitting 35×12.50r20 On Stock F250 – FITMENT GUIDE
When upgrading your 20s it’s going to be a challenge finding a tire shop that’s prepared to mount them since National chain shops could refuse to fit them since they have to abide by and meet the specs as laid out by the tire manufacturers.
For example, most national chains will refuse to mount a 12.50 tire on a 20” OEM rim because it does not meet the spec from Nitto even though they fit and ride quite fine. So, what are your lift options for your stock F250?
Biggest Tires on a F250 – Small Lift (2”+)
Installing a lift/leveling package with adjustable coilovers immediately widens your tire options. F250 kits are simple and affordable, offering radius and pitman arms as a direct fit. Side note: If your truck is still under warranty, make sure you understand the implications you have a future claim.
With a small leveling kit, run 10” wide and 35”x10.5”, needing minor plastic trimming. It’s a decent size for the lift!
- The stock F250 height and SFA suspension enable easier fitment of bigger wheels and tires compared to the 1500.
- A 2”-3” leveling kit suffices.
What if you go bigger – let’s say 4”, what are your options?
Will 37s Fit On A Leveled F250 (Offset/Clearance/Trimming)
The Ford F250’s popularity invites larger tire upgrades, especially the 37” sizes, enhancing its appearance. Opting for 37×12.5 on 20” wheels with a 2.5” spacer kit in a leveled F250 is a common choice. Using 2” caster shims helps restore the caster angle.
With 0 offset rims, tires stick out about 1 inch beyond the fenders. These setups with zero rub often require minor plastic trimming, depending on the chosen offset and tire tread pattern.

F250 User Feedback/Recommendations
Let’s now look at a few real-world examples from F250 owners
F250 User Feedback/Recommendation #1
You’re mistaken about rub for factory offset wheels. There will be no rub anywhere for 35×12.5 on the body or suspension for ‘19 or ‘20. The slight difference in suspension height on the ‘20s will neither improve nor worsen this as the fenders, radius arms, and sway bars are all the same.https://www.ford-trucks.com/forums/1610434-will-35×12-50-r20-rub-on-stock-height-on-new-2020-a.html
37×12.5 will rub on radius arms and sway bar regardless of lift or level, but will not rub on the body anywhere on factory offsets. It’s when people change the wheels to clear the suspension that they begin to hit the body.
F250 User Feedback/Recommendation #2
For what it is worth, I tried to put my 35×12.5R20 tires and rims (Fuel Assaults 20×10 -18 offset) from my 2016 Ford F350 the day I bought it and they look awesome but rub a bit much on the front fender at the bottom left at the very bottom.
I think I could remove the plastic piece that is attached to cover the seam and possibly get away with it but I have decided to get a leveling kit to help clear that one rub point.https://www.ford-trucks.com/forums/1610434-will-35×12-50-r20-rub-on-stock-height-on-new-2020-a.html
