I recently just leveled my truck out with the Loaded Quicklift from Rancho along with the RS9000XL shocks in the back and now I am ready to move forward with getting me some bigger tires.

I plan on just using my stock rim cause I don't mind the look of it and also I just don't really care to spend the extra cash if I don't have to at this point either.

Right now the rim I have on there I believe is the 18x7.5 or whatever has been mostly standard on the 2012 F-150 Lariat trucks that are just 4x2. I can provide pictures if needed, but I am sure from what I have read around here it's the 18x7.5 rim.

The tires on it are 265/60/18 and if you do the little tire conversion to metric it comes out to 30.5x10.4x18.

The question I have and yes I know that most of you might just post links to other threads on this forum, but what is the biggest size that I can really put on the truck without it rubbing or causing any problems?

The tire I was looking at is the Toyo Open Country M/T that is 285/70/18 and metric conversion comes out to 33.7x11.2x18 and the width really isn't much off from the tire already on the truck, but of course the height is and I have measured to see if there would be enough clearance and it looks as if there will be to me.

Only question I have is for all of those that have upgraded to this size tire and have seen no issues or have been ok so far?

Any input would be greatly appreciated!

you will be fine with that size with a level. When i level, I am going to 275/65/20

Thank you both for the info!

I have actually been playing around and changing up my idea on sizes, but not sure at this point yet.

Another question I have is that my truck has the 3.31 gears and do you think going with the tire size of close to 33" would really kill my MPG that much? I know that going bigger will ultimately kill MPG no matter what and it won't stay the same, but will going bigger on the 3.31 gears be really bad and also will it hurt anything as well?

Just kind of some stuff I thought about while looking and reading a little more into all this stuff.

Lower gears will help your MPGs a little in the city but hurt MPGs a little on the highway.

I just put Michelin LTX-AT2's in 275-65/20 (34.1" Dia.) on my unleveled XLT and have no rubbing on level ground. Slight rub on angled surfaces at full lock, which is why I'm going to install the Rancho Loaded struts or equivalent very soon.

You should be fine with a 33" tire.

Post up some pics of your Rancho's and how much lift did you get with them?

Thanks for the input as I really appreciate it and I can tell you that from installing the Rancho Loaded Quicklift on my truck I got exactly 1.75" of lift in the front and kind of shocked that what they actually advertised on the box is the truth!

Only reason I am shocked is cause there are so many products out in this world that say one thing and you get another, you know? I'll take some pictures and add them on here ASAP cause I would like to show off my truck.

It's nice having something BRAND NEW and being able to upgrade it over time. I can also really say that the ride on the old shocks/struts vs. the Rancho Loaded Quicklift and RS9000XL shocks in the back is really a big night and day difference in my opinion and I'll be able to really validate that as I drive more and more, but right now I am completely happy with spending the money and time it took to put them on at work.

By the way, if you do end up buying those to put on your truck. Then I really suggest that you put them on yourself cause it is EASY! There is no reason for you to take them to any place and spend whatever they are going to charge you. I know that they suggest you do the alignment afterwards, but my boss talked to his dad who owns a little performance shop that has put on plenty of these and they never saw any change in needing to actually align the truck again.

Overall, I will say that they are a very good buy!
