Ok, I have been looking into getting new wheels for my JK. I do know the stock ones are 18x9, I think. However, the site is asking for information that I do not know and I would like some help. There is a menu asking 18x9 on 5x4.5 and 5x4.75, BS: 4.50, OS: -12.
I do not understand that last part. Could anyone help me understand it an possibly tell me what ones would fit my JK.

Thanks,
Phil

 

those wheels wont work on your jk you need 5x5 bolt pattern

 

There is also.
5x5.5 and 5x150, BS: 5.00, OS: 01
5x5.5 and 5x150, BS: 5.75.0, OS: 20
What does it all mean?

 

There is information in the FAQ's stuck right to the top of this modified area ...

The bolt pattern for all JK wheels is 5x5, or sometimes you will see 5 on 5. So a 5x4.75 or 5x5.5 will not fit a JK.

5x150 is the metric equivalent of the standard bolt pattern. 5x5 = 5x127 I think.

BS is BackSpace. Basically this is how far in our out of the wheel well the rim/tire sits. Backspace on stock rims is around 6.25". When going to larger tires, you generally want to move them further out, which is a lower (not higher) backspace number. A 5.0 BS is 1.25" further out than stock.

OS is Offset. This is another way of determining how far in or out of the wheel well the rim sits. It uses the rim width in the formula, so is a bit more confusing to work with. Find a chart or online calculator to convert this to backspace.
