To be specific. the 5" wide rim is for a tii, no? 

 

 

[Swiss 2002Tii]

Correct.  Originally fitted on Ti and Tii models.

 

I had a set of 4.5Jx13 wheels extended by 1", but the interior well is too deep, so they bind on the Tii calipers.  It would take a huge extender to make them fit, so not practical.

 

I have one 5jx13, looking for a second so I can extend them 1/2" to fit my 185 tires (and hubcaps).

Yeah, far too many folks looking for them too, at least here in Amerikah. 

 

FWIW, I took a 4.5 rim and had the inner welded section ( the area that catches the tii caliper) machined down so it did not interfere.  

 

But that's me.

Interesting... How much did you have to take off, approximately?

 

To me, it looks like I would have to go through the wall of the wheel.

 

Just did the full exposé in this thread...

I'm not 100% sure of the geometry, but I think had they not added the 1" and made that innermost well deeper, then the contact point would be at the second fold, not the innermost.  Do you recall where yours made contact?

[conkitchen]

My calipers where hitting the area in yellow. I also for safe measure ground off the high spot of the caliper. The calipers where reman's from Rockauto and looked to be "newer" castings unlike the OEM Ate units.  

 

I would think using a spacer and longer studs might be best in your application.

I measured a stock 4.5” rim.  The overall width was 5 5/8”.  The backspace (rear edge of rim to the rear hub face of the center disk) was 4 1/4”. To calculate ET (offset), you divide the width by two — which provides the theoretical center of the rim — and then you subtract this number from the backspace. I come up with ET36 for a stock 4.5” rim (my measured calculations often deviate a millimeter from the factory-advertised offset).

 

If you add a full inch solely to the inside of the rim (i.e., inboard of the rear hub face of the center disk), the overall width goes to 6 5/8” and the backspace goes to 5 1/4”. Calculating the offset, I get ET49. This is not a viable offset for an’02. To make it work, you’d need a spacer approximately 21mm thick (giving you an “adjusted” ET of 28mm).

Maybe I am completely misunderstanding where they added an inch to your 4.5” rims. You can easily verify whether the inch was added to the inside of your rims by measuring the backspace. Is it approximately 5 1/4” (rear edge of rim to the rear hub face of the center disk)?

 

My plan is not to add an inch to the existing rim barrel, it’s to place the center disks from the original 4.5” runs in new barrels, setting the offset at ET28. If you are using the original barrels, you must relocate the center disks to obtain a reasonable offset, say ET28.

 

If you add 1/2” solely to the inside of 5” “tii” rim, you’ll wind up with an offset of ET32. This might be workable but it’s still a bit high: a 4mm spacer would get you to an adjusted ET of 28mm. But running those on the front and ET49 rims on the rear seems problematic to me.

 

I believe you need to first measure the offset of your modified 4.5” rims, just to see what you have.

 

Regards,

Here is where the inch was added on mine.  Looks to me like they made the offset way too deep. 

 

I will pull one out and make some measurements.  Thanks for the wheel geometry lesson.  Never looked into it before!

The fact that one of these new welded seams is visible from the face of the rim, and that it lies in front of the center disk, suggests the center disk has, indeed, been moved — this is a good fact — and that the offset is not as crazy as ET49.

If you think you know something, you probably know very little! I am reminded daily how little I really know about ‘02’s!

 

Piqued by Swiss 2002Tii’s widened-rim issues, I retreated to the basement, for prayer and reflection... well, maybe more reflection than prayer. I pulled out a 5” (tii) rim and a 4 1/2” rim. The first three photos show the shiny 5” rim on the left and the rusty 4 1/2” rim on the right. And... the plot thickens.

 

5” (tii) Rim — The smallest inside diameter of the barrel is 11 1/4”, as shown in the fourth photo. Conversely, the overall outside diameter of the center disk is 11 1/4”. The “backset” of the center disk alone is 3/4” (the distance from the rear hub face of the center disk to the rear-most edge of the four center disk arms), as shown in the fifth photo. The angle of the photo and my lack of a third hand makes the measurement appear to be closer to 7/8”; it’s not.

4 1/2” Rim — The smallest inside diameter of the barrel is 11 1/8”, as shown in the sixth photo. Conversely, the overall outside diameter of the center disk is 11 1/8”. The “backset” of the center disk alone is 1 1/8”. I couldn’t get a photo without a third hand...

 

In conclusion, both the barrel and center disk of the 4 1/2” rim present potential conflicts not present with the 5” rim. Who knew? Certainly not I.

 

So... I’d guess that offset alone is not a full explanation of why 4 1/2” rims conflict with tii calipers. And using a 5” rim as a starting point for a widened 5 1/2” rim likely eliminates those potential barrel and center disk conflicts, reducing the “challenge” to getting the offset right.

 

Regards,

 

Steve

Many thanks Conserv for looking into this in detail.  For sure, a third hand would be helpful for accurate measureents and photos.  Having the 5" for comparison is very helpful.

 

Conclusion seems to be a continued search for a second 5Jx13 is in the cards!  I'm really motivated to put my hubcaps on for a classic look!

I noticed that the recent 73 Agave 2002 auctioned on BAT had 5x13 steel rims. I assumed that they were tii rims.

Well the spare rim is in fact a steel 5J13 dated 2 72 and manufactured by Lemmerz in Germany but it does not have the usual "BMW" lettering stamped in the hub area.

Instead there is an Opel logo stamped in the hub and as we all should remember the Opel GT and other Opel models during the O2 era used 13 inch rims with the same 4x100 bolt circle. You may have better luck finding Opel 5x13 inch rims at the wrecking yards. And since you are modifying anyway you should keep tii rims original.

That particular spare 5” Opel rim, with the re-bodied Agave car, was also unusual in that it had multiple slots around the perimeter of the center disk — not just four “handholds” — unlike an ‘02 rim.  I’d say look for both ‘02 and Opel rims. I must admit: here in the States, I haven’t seen a ‘70’s Opel in 30 years. But Europe must have lots more!

 

Best regards,
