If you have 265/70r17's as your stock size, you can run the 285/70r17's with out the leveling kit, but the leveling kit would make it look real nice.

I am also running 315/70R17 on my Expedition (stock)(w/weld wheels)
I have NO VIBRATIONS
I didn't want to cut the black plastic so I spaced the front bumper out 3/4"
I ,as others have stated get a little rub on the frame at full lock
(NO BIG DEAL)
Picks are in the gallery

There won't be a big problem with going with the "P" rated tires as that's what 99% of F-150s come with stock anymore.
An 8 ply tire is kinda overkill for a F-150, 6 is best, and 4 will do the job.

Second set is called the "aspect ratio", it is a ratio of height vs section width...the closer too 100, the taller and narrower the tire, and the closer to 0, the wider and shorter the tire.
Are you sure that the stock size is 255/75r16 instead of 255/70R16?
It's been a while since I've seen a 255/"75"R16. I'm not real sure if you can get the size you are looking for in a truck tire...but I may be wrong.

You can use the following chart to get an idea of how width and height chance with different sizes, compared to your oem size. Or you can google "tire calculator" to find differences in tires as well.

I had 35x12.50-16 Thornbirds on 16X8 wheels with 3 1/2" backspacing with a 2" body lift. All I did was trim the air dam a little and remove the mud flaps. I have not touched the torsion bars. All i had was a little rub on the frame but that was from the sidelugs. Tires actually measured 14.50 from sidelug to sidelug.

Just to let you know, the Duelers had a 30 day test ride on them. Took back the
P265's, got the LT265 (50,000 mile like most of them)...big difference in the braking and handling - got rid of the understeer and slower braking of the P rated tire.
Dont settle for less than the rating on the door jamb.. ( paid about 110 each on sale)
Later, off to the Vermont woods in a couple of days.

255/70/16 is 30.1 inches tall 265/75/16 is 31.6 inches tall. This translates into 3.2MPH difference. Speedo reads 60 you are actually going 63.2MPH! You will lose a small amount of low end torque, you will notice this when taking off from a stop. The loss probably will not be that great and you may hardly notice it at all. The 265's will be wider by approx 1/2 inch or so, handling will inprove as well as cornering. Hope this helps!

I know if you work from the numbers that is works out that a 265/75R16 is about 1'' bigger, but please keep in mind every tire manufacture makes there measuements at a different spot. In my past life I worked with and engineering group at Ford. There was a large push to put a 215/50R16 on the SVT contour that came with 205/55/R16 Goodyears. Ford switched to the BFG G force 215/50R16. They got there larger number on the sidewall but the 205 goodyear was accually a wider tire. Goodyear measures the contact patch, BFG measures sidewall to sidewall.
My feelings are this, 255/70R16 is your factory size. They offer a 265/70R17 as an option (4x4 lariat or fx4) The 265/75R16 is very close to the 265/70R17.
You will notice nothing in switching to the 265/75R16. That is a very minor size change. If it was me I would be going to the 285/75R16.
That seems to be a easy, no issue, up size to switch to.

Using the goodyear rt/s as the guide for my measurments, as they are typically the stock tire that comes on them, the measurment are 1 1/2 inches taller. This WILL make a difference!! Using a revolution formula for the diameter of the tires your speedo WILL be off 3.2 MPH. This is a fact, check it, recheck it, and check it again, but, it is what it is. As far as performance you may not notice the low end power loss, if a driver doesn't pay attention they will never notice it. As for the 265/70/17 they are the same height but they are wider. If you want cornering get stiffer sidewalls ie:low profile tires and larger rims. the larger rim and less sidewall they rougher the ride but better handling. The smaller the rim and the larger the sidewall the smoother the ride but less ability to handle cornering at higher speeds. This is all due to the give of the sidewall of the tire. Yes bubahyde very good point about comparing tires of the same brand or taking actual measurments, make sure the rim mounting width is the same also.

If I don't lift my truck the biggest tires I can go with are 29in tall 265/65/16 is that correct? And if I add about a 3.5" lift I can add 33in tall 285/75/16? What are the 2.5" blocks for? Also the price that was listed on here by someone said this was close $600.00 - $1,500.00 I assume this doesn't include tires correct?
By the way anyone in San Diego, Ca. Know of a good place to go to get this done beside PG I hear they are really pricey. What I would like to do first is put larger tires on my truck without having to change out the stock rims or lift it. So I guess I can only go with the 29in tall 265/65/16's does anyone make good meaty looking tires for this size.
