18x9.5 +35 with 235 40 tires on e90?

mj777 · 07-23-2023, 09:21 PM

I have a 2007 e90 328i and just got Godspeed lowering springs and haven’t put them on yet and I was looking at getting a square set up (maybe run spacers in rear?) 18x9.5 +35 and wanted to know what tire size I should get without having to do modifications, or rolling fenders. The springs will lower front by 1in and rear by .8in (what it says not sure if it will be exact) and I was thinking 235 40, or 245 40… the stock rims are 16’s on 205 55

255/35/18 is the OEM rear size for an 8.5 wheel, but should stretch to the 9.5 just fine. I wouldn't run anything narrower.
