A 9 inch wide wheel with 6.22 inches of BS is gonna stick out about 3/4 inch farther than your OEM wheels.

 

Is there a simple way to explain what calculations you did to come to that conclusion? I dont understand backspacing and offsets either......Thanks!

 

Just use the OEM wheels as a reference. The OEM wheels are 7.5 inches wide with 5.5 inches of BS.

 

right, but different 9" wide wheels with the same offset can have different backspacing though correct?

For instance, the XD hoss 20x9's i want are +30mm but have 5.71" BS?

 

No, if the wheel width and backspacing are the same, the offset will be the same. Offset and BS are just two different ways of measuring the same thing. BS is the distance from the mounting surface of the wheel (where it bolts to the hub) to it's rear edge. Offset is the distance from the mounting surface of the wheel to it's center.

 

I still cant under stand that Off SET and BS I dont know,But here is another one I would like to ask about


20x9, 6 on 135mm Bolt Pattern
Backspace = 6.25 in.
Max Load = 2200lbs
Finish = Chrome
Hub Centric = Yes
Offset = 32mm



How far will that stick out,from factory,Im looking for the factory look,and would I need the Leveling kit with this rim and the 275/60/20 tires or will I be ok with the factory height...Thanks again Guys

 

Those will stick out 0.75 inches farther than the OEM wheels.

That website helped me understand backspacing and offsets. Nice to see pictures too. It's really not all that difficult to understand once you get it. Hope that helps.

 

Very Helpful....Thank you!

Hub Bore 87.1


NOW NEED TO NO IF I GET THESE RIMS THAT THERE HAVING A 1 DAY SALE ON TODAY WILL I NEED THE LEVELING KIT ON MY TRUCK AND HOW FAR WILL THAY STICK OUT,IM LOOKING TO KEEP THE WHEELS IN THE BEST I CAN..

MY TIRES ARE THE 275/60/20 LTZ THAY LOOK AWESOME

 

What backspacing is that?

 

This might help, my rims are 20x8.5 (virtually the same as the ones you speak of) with a -35 offset or 6.1 inch backspace (again virtually the same) The tire size is the same as your LTZs. I do have a 2" level kit but they would have fit without one. Here is a picture...

 

try this site too, play with the different setting for offset and you'll see the differences.

he means +35 offset w/6.1" BS....-35 would be sticking way out

not busting your *****, just clarifying
