Need help with wheel size

[jared1]

I have a 2012 f250 4x4 lariat and want to put some 20" black fuel hostage rims on it. But I don't know what size to get so need help. I was thinking about the 20x9 rims but I don't know the bolt pattern or offset. Can someone give me some help with this? Thank you guys. Oh and I want to put my nitto terra grappler 275/65 r20 on so should I go with 20x9 or 20x10?? Once again thanks guys.

Get out your trig function calculator and plug in the numbers:

How to Calculate the Diameter of a Circular Bolt Pattern

You can get the off set from your spare, but generally it is 0.

Cool. Thank you. Ok this may sound like a dumb question but where on the spare does it indicate the offset?

05+ super duties Have a +40 offset stock. And the bolt pattern is 8x170.

275/65r20 is only 34x11" so I would go with the 20x9 wheels. The 10" wide wheels would be great for running 315mm (12.5") wide tires and wider.

What kind of look do you want? if you want the wheels to stick out a bit get a +25 to +20 offset.

04 and older is a 0 offset. 05+ is +40 stock...

I really don't want to put fender flares on so I guess the 20x9 offset 14 would probably be the ones I want if the 20 offset will stick out. I don't plan on lifting or anything. I may add Fab Four bumpers later on but that's about it. Want to keep it pretty clean.

The smaller the offset, the more they stick out. If you want to keep them as close to stock as possible with no rubbing issues you want to get a +27 offset.

40mm-27mm=13mm=1/2" (aprrox) Since your new wheels are 1" wider you need to move the offset out 1/2" (13mm)

Oh wow I was looking at that all wrong then. Thank you. So the 20 offset will keep them close to stock but stick out a little further than the stock rims right?

correct.

These are with a 9" wheel.
If you were to go with a 0 offset, they would stick out 2" farther then stock.

If you get a +20, they will stick out just over 1" farther then stock.

And if they make a 8" wide wheel, you could run a +40 offset and that would be identical to stock. But then would be limited in the future to larger tires. I think 9" wide with +20 is pefect.


I run 295/70/R18 Nitto Terra's on my OEM wheels And love them. I will put them on Fuel 18x9 +20 in the near future.

That's great thanks for the help I appreciate it.
