Biggest Wheels & Tires Possible on Stock 2021 F150 (Without Level)

[rathbunr5]

Hi Everyone,

I came across this video on youtube made by American Trucks. It discusses different tire fitments based on offsets without a level.

It seems that the 2021 F150 will fit a 34.5x12.5 tire. Me personally, I do not like to modify my trucks all that much but I do like an aggressive tire on the factory wheels without touching the suspension. If any of you out there plan on adding a more aggressive tire on stock wheels without a level I'd love to see pictures and hear back about fitment. Here is the link...

Wow great info. I was ready to level my truck once it arrives but now not so sure. Love the aggressive stance of the raptor wheels on the ‘21.

Bad news on the Raptor wheels. I just bought a set to put on my '21 XLT FX4 and the 17" wheels will not clear the rear brake calipers. They will go on, but will not spin once bolted down. I know there are factory options for 17" wheels so I was very surprised they did not fit, especially after watching this video. I do also have the max tow package, maybe that increases rear brake size? As you see in the video, no clearance issues in the front.

Max tow does increase the rear brake size.. Bummer for you man..

That’s disappointing to hear as I spec’d the max tow... I also have a 2nd set of wheels for my Raptor & was hoping they would bolt right up with new 34ish KO2’s

Truck has a readylift level but has 295/70/18 ridge grapplers on the sport 18's....looks amazing!

Max tow does increase the rear brake size.. Bummer for you man..

It's actually the rotors that are bigger on the Lariat Max Tow Package

Does anyone know if 17s fit on the powerboost without max tow? I’m not sure if powerboost has larger rear brakes or not.

Yes, 17s will fit without MaxTow.

So with a 2021 Platinum with Powerboost engine, FX4 with the Max Tow package, is the consensus that I'll need 18" wheels, rather than 17"? I do not want to put a leveler kit on the truck.
