Fitting 35×12.50r20 on stock f250 – W/Without a Lift Kit

So you want to do a big tire upgrade to your F250 by fitting 35s on your stock wheels. You don’t have any lift kit installed and prefer not to fit front spacers, or change the OEM wheels either. All you want to know is, can 35s fit on the factory OEM 20” wheels without any scrubbing or trimming of fender liners or any other modifications. Do most F250 owners seem to be running 35s with a leveling kit?

There will be no rub on the body or the suspension of an F250 when fitting 35×12.5 on ‘19 or ’20 OEM rims without any lift 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 on the sway bar regardless of lift or level, neither should it touch on 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 spec as laid out by the tire manufacturers.

For example, most national chains won’t 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.

Biggest Tires on an F250 – Small Lift (2”+)

If you decide to go big and install a package with adjustable coil-overs, your tire options will be much wider. Most of the kits for the F250 are super simple and there are many inexpensive options available. The upgrade kits include the radius and pitman arms which are a straight bolt-on bolt-off fit.

So with a small leveling kit, you can run 10” wide and 35”x10.5”. There will be some minor plastic trimming involved but nothing too crazy.

This is a pretty decent size for such a small lift! Wow!

That’s basically because these trucks sit quite high in stock factory form, plus the SFA suspensions, which allow you to run bigger wheels and tires with a lot more ease, compared to the 1500, for example. So if you install a small leveling kit of 2”-3” you will be good.

What if you go bigger – let’s say 4”, what are your options?  Check out the article below!

Will 37s fit on a leveled F250 (Offset/Clearance/Trimming)

The Ford F250 must be one of the coolest trucks ever built by Ford. It, therefore, comes as no surprise that it’s so popular and that so many owners fit bigger tires to these vehicles to enhance their appearance even more. Being such a big truck, 37” tires are becoming increasingly popular since they fill those arches so well and really enhance the aesthetics even more. So what are your wheel options when fitting 37s to your F250?

You can fit 37×12.5 on 20” wheels to a leveled Ford F250 with a 2.5 spacer kit. It is recommended to fit 2” caster shims to restore your caster angle back to the factory setting.  With a 0 offset rim, the tires will stick out past the fenders approximately 1 inch.

These offsets with zero rub are very popular with these 37×12.5s. There might be some minor plastic trim required, depending on which offset rim you opt for and how aggressive the tire tread pattern is.

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.

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.

This is all for factory wheels. Get stupid enough wheels and you can make a 33” rub×12-50-r20-rub-on-stock-height-on-new-2020-a.html

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. We will see how it goes. As far as putting the tires on the stock rims I would not feel safe having that wide of tire on a 9 inch wide rim. I will post how the leveling kit works out with the aftermarket tires and wheels.×12-50-r20-rub-on-stock-height-on-new-2020-a.html

F250 User Feedback/Recommendation #3

stock tires on 20″ rims are 34.1″ +/-…so going to 35’s shouldn’t be an’s the width that could cause rubbing.. If towning, I think the 295’s would be better vs 35’s from what others have said


For all your fitment queries, head over to:

They have tens of thousands of examples of various tire fitments on all the popular trucks with feedback from the owners on what is required to make the wheel fit.×12-50-r20-rub-on-stock-height-on-new-2020-a.html


The nice thing about the F250 is that it’s packed with power, which means with 385BHP to 475BHP you can easily fit a 40” tire and it wouldn’t really feel it. You have to make sure the vehicle you are fitting the oversized tires on has the capacity to lug around this heavy unsprung weight. Bigger tires can negatively affect your MPG if you go too big and way outside the manufacturer’s margins.

Based on thousands of F250 owners providing honest feedback on the website, we are able to get helpful, real-world examples and fitment data of what does and doesn’t work on the F250 and many other trucks.
