Wheel question

[Evil PSD]

Looking at a set of wheels 18x9 -12 offset with 4.5" bs for my 2010 f250. How far will these wheels stick out past the fenders? Thanks

If I'm not mistaken, 05 and above need a 6~6.5 backspace (since offset changes based on width, I can't give you off set number). Any way, if you need a 2 inch spacer to put new wheels on my 2003 (made for a 4.5BS), then it's logical to deduce that those wheels will stick out 2" on your truck compared to a wheel with the proper '05 and up backspace.

They should stick out about 1 inch.
I have 18x10's with 4.5" backspacing and mine stick out about 2", here's a pic of mine:

Your stock wheels are 8" wide with a +40 offset. So 52mm + 1/2" = 2.5"

The rim face will be 2.5" farther out then the stock wheels. How far out past the fender this will be I don't know.

Just a heads up, your tire width will give it some more.

And someone up there^^^ said his stick out 2". It looks like his tire sticks out 2", the wheel is probably sticking out about 1".

here is a pic of the same rims on a 2005, i have the same size on my 2010 and they fit the same i just dont have a picture of my 2010 down the side. this is with a 12.5" tire, if you get a wider tire it will stick out more

thanks for the response guys, too far out for me, i like the look but do not want to chip my paint, what backspacing with stick the wheel even with the fender but have the tire stick out a tad?

[travisH3]

check out 0 offset. thats more what your looking for. It will have the tire just barely poking out a bit. i couldnt decide which one i wanted 0 or -12. both look really good but i just had to go with the low and wide look

With a 9" wide wheel stick with a between 10+ and 25+ offset. Any offset - is just too far off from stock. Forget backspacing focus on offset.

Seriously!?!

Take a look at this web site and see how off set CHANGES with wheel width, but backspace DOES NOT. To be more specific, a 5 inch backspace is going to be the same on any wheel, but a 9 inch wheel is going to have a different offset than an 8 or a 10 inch wheel to get that SAME 5 inches to the mounting plate. When it's all said and done, backspace is what is going to keep your tires away from your steering components whether it's measured in mm from the wheel centerline, or inches with a straight edge and a tape measure on the inside.

Yes seriously. Wheel width and offset give you your backspace. 08+ fords have no problems clearing steering components. He is only going 1" wider on his wheel, as long as he is more then -12.7 mm on his offset from stock he will be fine.

Forget backspace and do 3rd grade math to figure the change in rims!
