Wheels Offset

[marioman]

Does wheel offset matter when replacing wheels?

 

[bryan28]

It will make a difference in how far a wheel either sticks out of the wheel well or how far sucked under the wheel well it is.

The more positive the offset the further under the wheel well.

The more negative the offset the further it will be towards the outside of the wheel well.

How do I determine the lug position? We have a five lug array. But don't know what or how the measurements are determined

Ram 1500 wheels are a 5x5.5" or 5x139.7mm pattern.

Stock offset is +19mm

Here’s -18 offset on a 20x10 for reference, if it helps any.

Hmm. Looking at some wheels that are 35 offset... How thick a spacer would I need to bring them back out and would it be safe?

Look at different wheels!

+35mm? You'd need roughly a 3/4" spacer just to get them back out to the stock +18mm. Like stated above, I'd look elsewhere

I'd stick with a -24 mm max on a wheel offset , but to each other own . You could run a 2" spacer but I'd get a diff wheel .

The more negative offset the higher the load on wheel bearings and such .

A ( 0 ) offset will put your tires about 7/8" outside the fender , so figure from there as a + or - in millimeters.

Most of the wheels that are being run on here and that I've been looking at run from +1, 0, -1, -12, -18, -24, -44

I'm currently looking at some Fuel "Beast" (D654) 18x9 with a -12 offset

 

[Ramitiner]

So I'm getting 3/4"-2"... Which one is correct?

 

[Ramitiner]

Our wheels are 18 offset? Though it was 12???

Stock is +19mm (+.748"), so if you ran a +35mm (+1.378") you would need 5/8" of spacer just to get back to the stock backspacing. After that point any additional thickness of spacer will start pushing the tire assembly outside the factory setup. Chances are you'd have to run a spacer just to bolt the fronts on cause chances are the tires would hit the UCA with that much + offset.

 

[Ramitiner]

So not even an inch? That shouldn't be so bad

Thank you btw. 5/8 really shouldn't hurt the bearings all that much, right,?

 

[yortnodnarb]

Why don't you just buy wheels with the spacing that you want??

 

[GIJoe2010]

Exactly. It will be safer and cheaper.

Marioman if you haven't done it already, check out customwheeloffset.com. There are a bunch of pics of trucks and they tell you what wheel, wheel and tire size, offset of the wheels, etc. It may give you some more ideas. Good luck!

Keep in mind,the higher the negative # the better the stability will get to a point BUT also remember its gonna put more strain on bearings and im sure there will be some amount of axle flex,how much I couldn't say....
Its the same deal on 18 wheelers when they go from duel wheels to super singles..
