1955 f100 rear tires
Hi guys and girls...I am new to this forum and i thought i would ask a question, maybe somebody here can answer. I put a 01 ford explorer 8.8 rear end in my f100. I was wondering what is the biggest tires/wheels i could fit in the back. i also installed a rear 4 link suspension. If you have done this before or could help me out that would be awesome.

Welcome to the forum. There's no easy answer to your question. Whenever you make custom changes to something you toss all the rules out the window. It'll be up to you to do some careful measuring to determine what size wheels you need and with what offset, to maximize your tire capability. There's plenty of room back there for some pretty big meats, but how big you can go will be determined more by what size wheel you run.

No problem, but again it's not about diameter, its about width and offset. Rule number one when building custom cars and trucks; don't ever depend on what someone else did to base your decisions on. No two projects are totally alike. Especially in the wheel and tire department. Do your own research and measuring and you'll only need to do it once. This is 35 years of car building experience talking. 
As i said above, with the right offset wheel, you can fit a pretty fat tire back there, without tubs or special fenders.

I just put wheels and tires on mine this weekend. 17x8 wheels, 4/12 inch backspace zero offset. The tires I used are 225/60r17's. They look nice. Not a lot of room on the font, and the 225's filled in nice.
To figure out rough measurements, you can use this formula, again rough est. See below
Section Width
Following the letter(s) that identify the type of vehicle and/or type of service for which the tire was designed, the three-digit numeric portion identifies the tire's "Section Width" (cross section) in millimeters.
Typically following the three digits identifying the tire's Section Width in millimeters is a two-digit number that identifies the tire's profile or aspect ratio.

Following the letter(s) that identify the type of vehicle and/or type of service for which the tire was designed, the three-digit numeric portion identifies the tire's "Section Width" (cross section) in millimeters.
P225/50R16 91S
The 225 indicates this tire is 225 millimeters across from the widest point of its outer sidewall to the widest point of its inner sidewall when mounted and measured on a specified width wheel. This measurement is also referred to as the tire's section width. Because many people think of measurements in inches, the 225mm can be converted to inches by dividing the section width in millimeters by 25.4 (the number of millimeters per inch).
225mm / 25.4 = 8.86"
Sidewall Aspect RatioThe 225 indicates this tire is 225 millimeters across from the widest point of its outer sidewall to the widest point of its inner sidewall when mounted and measured on a specified width wheel. This measurement is also referred to as the tire's section width. Because many people think of measurements in inches, the 225mm can be converted to inches by dividing the section width in millimeters by 25.4 (the number of millimeters per inch).
Typically following the three digits identifying the tire's Section Width in millimeters is a two-digit number that identifies the tire's profile or aspect ratio.
P225/50R16 91S
The 50 indicates that this tire size's sidewall height (from rim to tread) is 50% of its section width. The measurement is the tire's section height, and also referred to as the tire's series, profile or aspect ratio. The higher the number, the taller the sidewall; the lower the number, the lower the sidewall. We know that this tire size's section width is 225mm and that its section height is 50% of 225mm. By converting the 225mm to inches (225 / 25.4 = 8.86") and multiplying it by 50% (.50) we confirm that this tire size results in a tire section height of 4.43". If this tire were a P225/70R16 size, our calculation would confirm that the size would result in a section height of 6.20", approximately a 1.8-inch taller sidewall.

The easy way to figure out tire size without doing all the math is to go to a site like NITTO tire and look under the specs tab. It will give you width and height as mounted on a specific wheel, plus wheel width suggestions. The sizes will correlate to other brand tires as well, size is size.

Meaning, some tyre manufacturers will create versions of a tyre that is not the width stated on the tyrewall. Some of these are vehicle specific. Some Kawasaki bikes were sporting 180 section rears ( in the name of fashion ), however the tyre was actually a 165, to get the bike to turn. Honda S2000 225 section Bridgestones were actually closer to 240. Just 2 examples, where 'size is size' isn't!

I know what you meant, and I understood the accent, great friend is an Aussie.
I know you can't go by tire sidewall marking that is why I suggested going to a web site for the tire manufacture to get actual measurements not the BS they put on the sidewall.
You would have made it more clear by quoting DGMFORD who is the one who posted all the math using the sidewall marking as I did not say anything about tire marking.

I did mean to quote you, specifically the 'size is size' bit.
Anyway, moving on.....

It is a relatively simple task to measure the width of your bed, width of your fenders, and mounting flange width of the rearend. The stock fender will have a maximum width of 11 inches so you know how wide the tire/wheel can be. The width of the rearend will give you the info you need to establish a backspacing that places the wheel/tire in the center of the fender opening. Here is a drawing I did some time ago when I was spec'ing wheels for a 56 F100 that I had installed Corvette IFS/IRS on...
