Rim Width Question For The Gurus

[Darkboy]

Can anyone tell me how is the width of a rim is measured/determined.

Is it measured from the total width of the rim from both outer edges of the lip (inner and outer edges), or is it measured from inside the lip?

Reason I ask is, I have just had delivery of a replacement front Super Advan 17x8J +35. This is the exact same spec (well meant to be) as the one its replacing but when I look at the profile of the spokes, it doesn't appear to be the same. The spokes don't come out as far.

When I got the ruler out it appears to be almost a 9inch rim when measured from outer edges but has 17x8 stamped on the inside. Could it be a blunder on the manufactuers behalf?

I'm sure there wasn't 2 variations in spoke design for this wheel but I'm no expert on this.

Hope this makes sense and sorry for the naivety on my behalf.

cheers

the width is most likely the same...u probably got the wrong offset wheel. The offset of a wheel determines how curved in the spokes are for the same wheel. Another factor is the disk of the wheel, whether its low caliper or high disk clearance wheels also determine how the spokes are curved. Hope that makes sense. two identical width wheels of the same model may look different depending on the offsets.

Yeah I understand everything you're saying and this is I'm confused coz everything is identical.

The offset, rim width and size are all identical to the rim I'm replacing, its just the spokes dont come out as much as the ones I already have on the front of the car. Maybe there was 2 different face designs I dunno.

I got the rim from Yahoo actions Japan off a wheel dealer and everything he advertised matches what is on the rim so I now have frown written all my face...just cannot understand whats wrong.

if it is exactly the same model, width and offset, then more than likely its the disk thats different. Chk on the insides of the spoke or on the sticker...it should have O, A or B something like tht...A is for high caliper clearance, O is low....jap wheels are a mystery sometimes...

Crikey its more complex by the minute. Heres some pics I just took with all the info.

1st pics says 96/12

2nd says 17x8J / 35 / L

3rd says SA3R 17-1

Other than these details I'm bamboozled.

is there a sticker somewhere? maybe a pic of both wheels...

Nah the only other sticker is a shiny square silver one and its all written in japanese. The old rim is still on my car so I think I'll have to get it off tomorrow nite.

thanks heaps anyway man

The width of the rim is measured where the tyre sits, if it's a 8" rim it should measure 8" (203 mm) inside . The rim you have there is a 17x8 and 35 offset.
