questions about offsets and rim widths

What is the highest numerical offset that will fit on our 6ers. I know that wheel widths will also affect how much offset we can go so anyone feel like giving me a lesson so I can order me some new rims.







Pretty please.

Are you trying to stay close to stock sizes (width/offsets) or looking for something MORE aggressive or REAL aggressive?

It's not an exact science. Tell us what tire size and wheel widths you are thinking of and I can give you some ideas.

Is there a rule of when it comes to rim widths and offsets. For example can skinnier rims (8.5) use a greater offset than say a wider rim (10.5). Or is it the other way around.

I have found 3 sets of rims that I really like. They are all 20" but three different widths.

The 8.5 wide rims have an offset of 15 (I know these will fit no problem)

The 9.5 wide rims have an offset or 25.

The 9.0 wide rims have an offset of 20 with rear 10.5 wide rims at 27 offset.

Rule of thumb is to increase stock offset by half of the increase in wheel width. So if stock is 8.5" wide with 14mm offset and you increase wheel width to 9" - that is a 0.5" or 12 mm increase - so increase offset by 6mm to 20mm in this case.

This keeps the wider wheel centered over the hub the same as the OEM wheel.

But wheel fitment is not an exact science since you have a few issues to deal with. If you go with too high of an offset the inside of the rim will rub on the strut. Too low and the tire will rub on the fender.

The safest thing to do is go with a fitment someone else has used and is known to fit.

Maybe you should start a thread about offsets. Everyone could list what they run.

I just posted this on another thread.

For anyone looking to replace their stock wheel/tire setup this is a great tool to play around with.
All you need to know is what your stock setup is, wheel diameter, width, offset and tire size.
Once you plug in those parameters you can make the changes that your considering and see the effect it will make on the fitment.
It helped me zero in on the perfect fit for me,
