Tire size question

I bought my truck recently. it is a 2018 F250. It has Black Rhino wheels on it. It currently has 275/65/18 tires on it. I am wondering what is the largest tire I can put on the stock truck without a lift. The wheels say they are 18x9 with a 12 offset.

Depends on how you feel about rub and how different your wheel offset is from Oem. I’m not the resident expert on offset and backspacing. 35’s fit easy. 37’s will rub between 37 and 40 degrees of steering angle (the last 3 degrees of turn to full lock) with oem offset. Many on here are running 37’s with minor rub and using our brains to compensate. I’m ok with it because there is absolutely no body rub or other contact. I will be replacing my radius arms and sway bar in the spring to eliminate rub.
Here is my setup with 37’s, no lift:

These black rhino's are 20x9.5 with a 12 offset. The tires are 37x12.5 and do rub the radius arm just slightly at full lock.

These are Cooper AT/3's 285/75r18 on the stock XLT wheels 18x8 44 offset. They did not rub at all.

These are NITTO 37x11.5 on the stock platinum wheel 20x8 44 offset. They do rub at full lock.

If you are looking at 37's then use an 11.5 wide tire with your black rhino wheel and it will not rub. I can't speak for 35x12.5's rubbing or not as I never ran that size....however as stated the 285/75 does not rub.

325/65R18 on my truck. 34.6 inches tall, 12.8 inches wide. No lift, no level. Also no rubbing the mud flaps in front at full turn. And as you can see, the factory wheels that the truck came with.

Truck looks great!

how do you like those tires? I had them on my Tacoma before upgrading to the F250. I hate the goodyears that came on the truck. no traction in the mud or snow

295/65/20 will look real good also. 37’sruns a chance of rubbing which I didn’t like, the 325 was too wide for my liking and I would have had to run fender flares which I didn’t care for.

Beautiful truck! Would you mind d taking a picture down the passenger or drivers side from the back. I’d like to see how much they stick out. I was going to go with 285/65/20 but am tempted by this size.

Thanks ahead of time!

I really want to run 37's but the only 37x11's for factory 18s are freaking 420$ a pop...
