was the backspacing the same too?

 

The backspacing is 4.53" on the Akuza.....I'm not sure what the 951 is, but i though with the same size wheel, and offset that the backspacing is the same.

 

Is that true?? Why wouldn't they fit if a 951 will? What do you guys think?

 

backspacing and offset are two different things.

 

nope not true.

A 9" wide wheel can not have a 4.53" backspace "and" a -12mm offset. A 4.5" back space would be a 0 offset, and a -12mm offset would be a 4" backspace.

Let me see if I can explain this. Backspacing and offset are two different ways of figuring the same info. If you have two wheels that are the same size, example 18x9, if they both have a -12 offset, then they will both have the same back spacing. Which for that wheel would be a 4" back space. That is exactly why they are rubbing. Now lets say that one wheel is 9.5" wide, not 9". If they both have a -12mm offset than the 9.5" wide wheel would have a 4.25 backspace. The formula stays the same. If the same width wheel has the same offset, then it will have the same backspacing. The Titan is recommended to have a 5" backspace. My wheels are 20x9 with a +12mm offset. That gives them a 5" backspace. See what I'm saying?

Edit: see my next post down. I had my numbers mixed up.

yes what he said "idhitit2: :signed:

here is some more info you can read :readclose about backspacing and offset w/ pictures

Based on the info in that link, that means my backspace numbers are all off by about a 1/2". But the idea is what I was after. lol I have never added the "+1 to the rim width" so that means that that your -12mm wheels are in fact 4.53 offset. But the point I was trying to make is that if the other wheels are 9" wide with a -12mm offset, then they too will be 4.53 offset.

 

That is exactly why I am puzzled that the Moto Metals work and these wont, and they both have the same deminsions.

 

The AKUZAs might be for sale.......I dunno yet.....but if anybody is enterested in a good deal!

someone has got to be out of spec.

one of the reason i went with helomaxx is they claim 5.75" of backspacing... rancho claims that 35" tires will work with their lift kit if you have 6" of backspacing. But this was not good enough for me... I pm'd a lot of members on this board and the other board asking about the rancho and helomaxx to confirm.

life would be so much easier if everthing could just bolt in. :upsidedow

 

Hey EricCartmann, were you able to use the tpms in your helo's? I also have Helo Maxx 6 but haven't tried the sensors in them. I think I read somewhere that they wern't compatable

 

no i do not have the sensors in them. The helomaxx opening was too small. sucks I can't turn off that light. i'm about to take about my dash apart just so I can find that bulb and take it out... actually that will be my next question on this forum. "need instructions on taking out the bulb for tire pressure monitor sensor"
