TIA everyone.
I understand the OE wheels and tires are the following sizes:
F 18 x 8 ET42
225/45/18
R 18 x 9 ET30
255/40/18
So this is what's confusing me.
1) I'm currently running 10mm spacers with the OE wheels and tires. The look is perfect...I DO NOT want to extend the outer surface (street side) of the tire any more to the outside no matter what width of tire I use. I want to keep using the 10mm spacers so I can mount the OE 18's for longer trips
2) I know a number of you run a 245/275 combo with no issues but I want to use a 235/40/19 and 265/35/19 setup in Michelin PSS. (So, slightly taller than OE which actually is what I want, and slightly wider).
3) I'll be ordering wheels in 19x8.5" and 19x9.5" but the company wants me to specify the desired offset.
4) Assuming that the extra 10mm tire width and 12mm wheel width would be all to the inside, what should I specify as the offset? Am I correct in taking 10/2 adding it to 12/2 = 11 and therefore adding 10 or 11mm to the OE ET's of 42 and 30 to get the look I want?
