I am looking for aftermarket wheels for a 2006 f250 and found The ION 160's in a 20x9 with 4.5 BS and 0 offset. I love the wheels, but do not whant them to stike out like a low rider!!!!!! I hate the look of a truck with wheels sticking out 2 inch past the fender. I plan on putting a DR 2.5 leveling kit and a 4" block in the rear (replacing the 2") with 35.5 inch tires. Will these wheels stick out to far and look stupid?

Thank you for your help!!

I talked with various wheel and suspension companies and they all said something different!!!!! I heard everything from 4.5 inch BS to 5.5 inch BS are needed for an 2006 Super Duty. Which is right? Does anyone know what the factory 20;s have for BS?

Thanks again,

Nebraska

 

Backspacing can and should vary with wheel width.

If for example the stock wheel had a 4.5" backspace on a 7" wide wheel and you wanted to go to a 9" wide wheel, the backspacing will determine whether or not the extra width will stick out further or in more..

If you dont want it to stick out further than stock, take the difference between the widths and add it to the stock backspacing...but make sure you will have enough clearance!

 

Nebraska,

I am searching for the right wheel as well and have found the following information from searches in this forum and from checking out wheel stores. The 2005-2006 trucks have stock backspacing around 5.5 but this is on the stock 18x8 inch wheels. (I am not sure about the setup for the 20's) If you want to go to a wider wheel, like a 9 or 10 inch, the back spacing will be more like 4.5 to 5 to allow for the wider tire and give you the clearence you want. Typically, when searcing for wheels you wont be able to find a wider wheel with 5.5 to 6in bs unless you have it custom made. Regardless, though, when you go to a wider tire you will have some of the tire sticking out beyond the fender of the truck which ultimately can be remidied by flares. What width tire are you looking at?

 

[QUOTE=BlueOval350]Nebraska,

Incorrect!
Assuming that stock backspacing is 5.5"
If stock is 8" wide and he goes to a 10" wide wheel the Backspace would increase inorder to tuck the wheels inboard more(to keep the outer edge from sticking out too far). Less backspace means the wheels will stick out further!

If he increased the wheel width to 10" and went to 4.5" BS (from 5.5) the wheel would stick out 2" further than stock!

 

[QUOTE=fomocofan]In your example it would stick out 3 inches more than stock!

 

Yes, good catch!

If the backspace were to stay the same, the extra width (2") would stick out...in that example you would then loose and inch of BS causing three inches more to stick out!

Bottom line is, as I had said... if you dont want the tires to stick out and you go wider, you must increase the BS...if you have the room!

 

Yes, you are absolutely right that it would stick out further with the lower than stock backspacing but my point is that because he wants to go to a wider wheel and wider tire than stock you would have to go with a wheel that has less backspacing solely for the purpose of clearance. I was trying to make the point about clearence because there is a good chance of rubbing issues if you went with bigger tires on a wheel with the stock backspacing. Sorry if I wasn't clear.

 

He needs to check for clearance as we both have said. He needs to fiqure out how much wider the tires will be. This means section width of the new tire on the new wheel versus section width of the old tire/wheel. Half of the difference will need to be added to the inside of the current tire to measure for clearance. If he has more room at that point he can increase his BS to tuck the wheels in more.

 

I've never seen a Low Rider that had wheels the stuck out from under the fender!! I think that would defeat the purpose of the thing getting low. All the Low Riders I've ever seen had wheels and tires would go up into the Wheel Wells so they could "drag" the Frame.

 

Thank you guys!!! I am a newbie to aftermarket wheels. I found the factory 275/65/20 are 34.1 inches tall and have a sectional width of 11.3 inches. The tire I want 325/60/20 are 35.5 inches tall and have a sectional width of 12.8 inches.
From what I understand:

Factory 20x8 BS 5.5 inches (2.5 inches from hub and 5.5 inches toward truck)?

Ion 160s 20x9 BS 4.5 inches (4.5 inches from hub away from truck and 4.5 inches toward
truck)? Plus half the sectional width difference each way (1.5/2= 0.75 inches)?

This gets complicated!!! Am I on the right track?

Thanks

P.S. In refering to the "lowrider" look I can't think of the appropriate term.

 

Yes..Your new tire/wheel will be almost the same clearance inside (actual 1/4" further out than stock )

The outside of your new tire/wheel will be 2-3/4" further out than stock.

If you can live with that, you're ok...
If not you need to see how much clearance you have inside your stock tires and see if you can find wheels that will stick in more...I.E. 5.5" will pull it back in an inch or it would then only stick out 1-3/4"...

 

Thanks fomocofan!! I will have to do some thinking to see if 2.75 is to much for my taste. What wheels are everyone using when they lift their trucks?

The wheel manufacturers usual fiqure for inside clearance...That is why that combo is almost the same as stock inside. The usual combo will stick out. You could stay with an 8" wheel and a narrower tire??

Larger tires have to go somewhere...you either tuck them in more (find the right BS) or let them stick out...If you do careful measurements and find the exact BS you can split the difference.

If it were me, I would look for a different wheel.. Many manufacturers will offer more than one offset for a particular wheel..do some searching, and good luck!

20x8.5" with 5.25 BS

Even if the new tire is 1.5" wider:

the tire will be 1/2" further to the inside from stock
The tire will be 1-1/2" further out from stock.

However, due to the slightly narrower wheel the section width of the new tire may not be quite 1.5" wider..making the numbers slightly better!

Something to think about??
