20x8.5 40 offset (TSW Nurburgring) on H&R springs. 275/40R20

[TimmyATL]

I apologize in advance for this thread. I have done some research but would like yalls opinions. My questions are will this size tire rub? Also how does the sidewall bulge affect the contact patch when mounted on a 8.5 wide wheel? TSW does not make a 20x9 in a 5x114.3 bolt pattern in my wheel. Thank you all for your time and effort.

Do they make a 9.5"?  I am running a 20x9.5 35offset.  I am not running 275's on it yet, but I am pretty sure others have run similar size/offset without issue.

 

[TimmyATL]

no the widest for my bolt patter is 8.5

You should have a 9" or wider wheel to run 275s.

That is incorrect. I've put a snippet from the table found at (https://www.tsw.com/alloy_wheels_nurburgring.php) below. It has all the sizes and color combos for each bolt pattern, etc. You can get 20x10 for the rear, which should be fine with that size tire, and is what BPD ran. Not sure of the offset he ran. You may be able to run 20x10 in front as well, but not sure on that.

You could also run 18s all around as they offer 18x7.5, 18x8, 18x8.5, 18x9, 18x9.5. You could probably do an 18x9 or 18x9.5 all around with a comparable width tire for an 18.

19*9 is also an option, and the offset would make for decent poke from the wheel well.  Means shorter sidewall for correct tire diameter versus the 18" while allowing 275's and matching on all 4 corners for proper rotation and tire wear.  Bit of an odd size though 275-45r19.  But the Conti DWS are available in that size which is a great tire.

Thank you all for your input. Depending on the test results with my Nitto NT05 will determine if I go and try the M/T ET S/S.
