Is there a Michelin PS4 tire in the same width as BMW Star spec PSS 285/30/20?

From what I gather here the PS4 runs wider than PSS in the same 285/30/20 tire size even though the official specs from tirerack says they are the same. There are tons of pictures here confirming this.

Has anyone be able to find a PS4 tire that is equal to the PSS in this size? The reason being my BBS LMs (20x10) have an aggressive offset and the star spec PSS JUST clears my fenders in the back. I'm talking about maybe by the thickness of a piece of paper tight so getting the wider PS4 would def cause rubbing issues for me. Is there a star spec ps4 tire or similar available or has anyone tried running narrower 275 to see if its more closely match to the original tire?

Your best bet may be staying with star spec PSS. Running a narrower width will also mean a smaller diameter and will affect your F:R tire ratio.

I've ran 20x10 BBS LMR ET 18 prior to my current setup on my rear with the 285/30/20 PSS star spec. A 285/30/20 PS4S will most likely rub. I used a Michelin PSS 275/30/20 which BARELY cleared (with -2.2 rear camber).. the F80 also has slightly less clearance in the rear fender as well. I have tried the setup on both F80 / F82 - the star spec ZCP tires are actually closer in tread width to a 255/30/20 and 275/30/20 NON star spec PSS.

Thanks guys. This is what I was afraid of.

With my stock Star spec PSS 285 tire i rub slightly on hard dips since i'm lowered. Looks like there is no way i could run PS4 with this wheel setup.
