I have 540ix G30 and I will go 19s (lighter, good for handling, we have bad roads  ) and put 255/295 tires on it (+10mm front, +20mm back; already checked - overall size is good). I'm thinking 19/8,5 ET25 front and 19/10 ET41 back. Its basically the same setup as OEM 20s.
1. Is the offset OK? I've seen some people run ET36 back on 10s . Its like putting 12mm spacers front/back. Or with 36 and 20mm back, but then back is 8mm more out than front. I aim for best handling and no rub  .
2. Is 8,5 enough for 255s and 10 for 295s? Or go 0,5 more on each? For handling/sporty driving. This smaller concave or this wider flat? I think 8,5/10 is enough and it will be a bit lighter, but I've noticed sports/M cars have rather flat vs concave and dont know why.
Please save me! THANKS A TON!  |
FYI / Reference only...
Recently, purchased a new set of wheels (semi-forged), and tires (staggered setup) for my 540i xDrive M Sport. Here is the following info regarding my setup:
Wheels:
Front: 20x9 ET 30
Rear: 20x10 ET 42
Tires:
From: 255/35/20
Rear: 285/30/2
IMHO...this is a conservative setup!
