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

[turbospartan]

Thanks! Spacers are only in the back. Due to combo of sticking with 285 tires as well as no lift/level, my mpg has not been affected. Even if it has, it's not noticeable.

What spacers did you go with?

Can anyone confirm 295/70/18 will fit stock? Minor rubbing is ok.. just want to slap tires on and level later.

For the OP, do the KO2s in 285/65 provide any additional protection for the wheel itself? I’ve noticed that with the stock tires there is very little extra width to the tire that protects the rim from getting scraped on curbs.

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.

Thank you man. You saved a good amount of money and time. I was going to order 17" rims and just saw your comment.

I believe you are correct about max tow package. I think I read somewhere that the larger brakes with it won't let you go below 18" wheels.

I’d like to bump this.
also curios what I can put on stock wheels.
I’ve lifted my last 150 and had beautiful raptor wheels 35 KO2.
This time my wife wants to keep the 150 minimum adjustment, for now, lol.
I like my wheels and I live in Alaska would like a good tread all year tire, Load E even.
thanks

Just did 285/70/18 (34x11.5) Nitto Ridge Grapplers with the 2" readylift level. I like the width of the 285 over the 295 in my situation to ensure I have room if the suspension flexes while in full lock. I would think the same especially without the level. Its only .3" wider and taller with the 295's so if you are ok with a little rub, should be fine.

Hm.. might see if discount tire will slap a 295/70 on and do a little rub check.

Hi - do you have the max tow package? I’m hoping that 18” can fit with the larger brakes. Thanks

Just put on 285x65x20 KO2s (34.6" tire) on a stock truck. No level. No rubbing whatsoever. I do have 1.5" spacers on order for the rear as the rears are a little tucked for my liking. Otherwise, I am quite happy with how it turned out.

Any rubbing when going over bump forward or turning

My truck finally arrived, and I had Granger install an Icon Stage II kit and align it before they shipped it out. I am assuming the dealer installed them at the settings that the shocks came out of the box since they didn't have the tires to test fit. I purchased the 295/70/18 Michelin Defenders locally from America's Tire and they just barely rub on the crash bar, so I am thinking raising the front approximately 1" should resolve the issue?

I think I have plenty of room to raise the front slightly to eliminate the rub. I thought I read every (4) turns of the collar gets me 1/2" raise in ride height. Install guidelines don't exceed 2" of exposed thread, and right now I have 1" exposed thread.

2. THE SHOCKS SHIP AT ICON’S RECOMMENDED RIDE HEIGHT. ICON DOES NOT RECOMMEND ADJUSTING THE COIL BEYOND 0.8” OF THREADS BETWEEN THE BOTTOM OF THE TOP CAP AND THE TOP OF THE COIL NUT. ADJUSTING BEYOND 0.8” OF THREAD SHOWING WILL REDUCE RIDE QUALITY. DO NOT EXCEED 2” OF EXPOSED THREADS.

Anyone have insight or opinion by looking at the photos? It is drivable as is, just want to get it correct.

I'm debating 285/65r20 vs 275/65/20, so these pics help for sure. Since I'll be towing a 6000lb TT, not sure I want to put on a 2" level. I did see motofab has a 1.5", but still think it'll be too much when towing.

Definetly do not raise the front when towing. Asking for trouble.

Went with 285/60r20s back in December and will not be putting a level on it. It rides good as-is unloaded or when towing.

Thanks for this. I took your lead and put the same on my 2021 F1`50 Limited. Will probably get cursed for this, but I replaced the stock Limited 22s with Stock Platinum 20s, then put the same KO2 285x65x20s on. I like the look of of a bigger tire on this truck but wanted to keep it relatively stock looking. No lift or level. No rub.

Looks good. Any rubbing?
