BBS RS 211, Tire fitment issue

Post by v-wiz »

Over the weekend I mounted some new Hankook S1 Noble2 tires in 225/55/16, They look really nice, the rears appears to fit great, but upon further inspection it looks like they might rub during suspension travel. The front tires rub, both at the back and front of the tires. Luckily i called the tire shop and told them my issues, and they are willing to exchange for whatever size i need. Im really crunching for time since Socal Vintage BMW is in a week, i need to sort this issue out by then. What tire size would you guys recommend for these wheels. Thanks guys.

I run 225/50/16 Kumho's on my series one .
I've had these on two sets of wheels , the current 7x16 et 20 ,

and the previous 8x16 et 16 ,

I did have some tyre contact on the rear of the front inner wheel arch on full lock on the et 16 wheels but this was on the Lokari liners I have fitted . Without these there would have been no contact .
The circumference of the 50 series tyre is almost exactly the same as the original series one 195/70/14 fitment as shown here .

I see you also have a series one .
I would suggest that you downsize to 50 series and then all would be well .

Thanks for the feedback. Thats a nice comparison chart, i wish i knew about it before buying. Man im really afraid that even the 225/50 would rub? I think the offset on these wheels are et11.

I think the 225/50 size olympia suggested should work for you. Going from 225/55 to a 225/50 should be about an 11mm difference in total sidewall height (if I figured it right), giving you an extra bit of space for fitment.

The ET16 Remotec's I ran never touched the rear arch lip ( at top ) under suspension compression or with rear passengers but ET11 might , even with 50 series tyres , if your suspension is soft or lowered. ( 5mm further out than these )

This was the tyre to arch gap with all new suspension components fitted . It was probably fully settled at the time of the photo.

You shouldn't have any problem with rubbing on the front struts as ET11 is 5mm further away from the strut that the ET16's I ran, and they never touched.
IIRC though the series one arch differs from the later cars and I certainly had problems when I had 17inch et20 wheels with 235/40 tyres fitted catching on the rear bottom of the front arch lip on full(ish) lock.

I changed out the ET11's for the current wheels simply because where I live is " agricultural " and the sides of the car were getting covered in cow and horse shit every time I took it out ...... :evil:
Those are beautiful wheels you have though , I hope you manage to fit them OK.
Good luck

Thanks again, as far as the rears, i have Bilstein HD, with OEM springs, lowered at the lowest setting, so it is lower than yours, if i must, i will consider raising the height by one slot. There are no issues at all with rubbing against the struts, all the issues are with rubbing at the sides of the tires. At this point its a gamble with 225/50. I wish they had more options in 215/45.

225/50 tires Vic for an 8 inch wheel. I have rs211s and run 245/50 (tight fit) in the rear with 225/50 up front on a series 2 car. See you at Socal Vintage.

Thanks Ralph. It appears everyone is using 225/50 up front.

Got the 225/50/16 tires, same Hankook tires, the back is good, but the front still does not fit, im thinking even a 10mm spacer would not work. Whats my next option, 205/45/16? Guess i wont make it by Saturday.




Here is a shot of the wheel on the ground. As you can see the edge of the tire is hitting the edge of the body.

Wiz, 205/45's would be way too short, the proper aspect ratio for 16" 205 width tires would be 55 series, for proper 6er fitment [-o<

But I gotta wonder, are you SURE about the offset on those wheels :-k

Something ain't right, obviously we're not sure what, but this shouldn't be all that difficult to figure out either [-X

All 4 wheels are et11, and 8". Maybe they are to wide?

Very strange. The series 1 and series 2 can't be that different. What's weird is that it seems the tire is too tall AND too wide. The tire height has been beaten like a dead horse around here so that's almost a given that you should not have any issues with height.

And just because the tires wont roll doesn't mean the car can't fly. You can still (better) make it to the show on Saturday.

I'll have to take a look at your car if you show!!

I actually wondered about those wheels when I looked at the first photos posted.
For an ET11 wheel they seem to sit into the arches , certainly much further in than the ET16's that I had fitted..
Do you know the history of the wheels ? Is it possible that some previous owner has shaved some material off the inside face of the wheels effectively changing the actual ET ?
A straight edge and a good steel rule would allow you to measure the offset .
Hubcentric spacers may be your cheapest option/solution .

Gotta agree v-wiz, I'm running 17 x 8 ET20 wheels up front with 235/45's with no rubbing, true they are not 16" but all's good, and I'm not the only "lucky" one \:D/

And that's also on a series I 6er, just pointing out that 235's on 8" wide wheels with a 20mm offset should not be an issue :-k

There is a method of measuring offset, olympia57 is on the right track, check 'em out to be sure [-o<

I dont know what to say guys. The wheels look just fine, no alterations that i can see. The wheels are ET11 all around. I just wish i had some spacers sitting around so i can test them out. Im out of options, which is such a shame because the wheels look amazing on the car.


Here they are with 225/55/16

I'm struggling to understand this and offer a plausible diagnosis .
I had absolutely no problem with ET16 wheels and ET11 should take the wheel out away ,from the inner wells ,another 5mm .
ET is ET irrespective of whom the wheel manufacturer is .
Are the barrels reversible ? ie could they have been fitted back to front .
Where is the ET stamped , is it on both barrel and centre .
As I asked in previous post , do you know the history of the wheels .
My focus would still be on the wheels and I'd measure and confirm that the actual ET corresponds with the stamped figure .
Others are running the same wheels ( with presumably the same ET ) with no problems so it has to be the wheels .
I've looked a photos of the ET16's fitted to mine and the tyre is almost parallel with the top of the arch on the rear , yours should be +5mm . I haven't posted a photo as this thread seems to contain more photos of my car than yours ..... :oops:
Good luck

Don, i have no idea, im struggling as well. Ralph looked them over yesterday and we still cant understand why they wont work, but they just simply don't. The barrels are not reversible, The ET is stamped on the outside of the hub, and no i do not know the history of the wheels, all i know is that they were sitting in his grandpas garage for 18 years, it was apparently installed on his grandpas 5 series, i assume e28.
At this point im thinking of running 225/50/16. Or just to be really safe 22/45/16.

Thanks.

"et stamped on the outside of the hub" means the barrels could be something other than original, and therefore the et number is meaninglessness. It's the only possible explanation. I have 225/50/16 Kumhos on my 633, with et21 wheels (offset 10mm MORE to the inside than your wheels are supposed to be) and have more than a finger's width of space to the inside. They're not even close to any suspension part.

I think the next step is to get a straight edge across the inside rim to rim of the wheel and then measure from that point to the hub face . I shall measure my et16's and we'll see what that figure is . Remember that an 8 inch wide wheel is actually 9 inches wide edge to edge due to the J face that actually holds the tyre , hence my reasoning on measuring my et16's.
I'll try and do it later this evening .

OK .
Confirming my ET16 wheel .
A couple of photos and a schoolboy sketch containing schoolboy maths .......
Allowing for my old eyes , a bit of parallax error and calculations to the first decimal point it is only 1.5mm out , plus there is a small step on the hub face , but I think it's a check that will throw some light on this conundrum .

I just measured from the back of the hub to the back lip it is exactly 5 inches.
