I have scoured the forums, FB groups, etc. Everyone seems to have different answers.

I am looking at swapping out my 18x8.5 ET48 245/40/18 stockers for some new shoes.

2014 E350 - Sedan - Sport

19x8.5 F - 245/35/19
19x9.5 R - 285/30/19

What offsets should I run to be flush or just inside flush? I keep seeing ET42 front and ET35 rear - but I want to verify with people what they are running. I am stock sport suspension - no plans on lowering car.

Thanks in advance.

You should run 255/35 front on 19x8.5 with et39 (+/- 2mm) and 285/30-19 on rear 19x9.5 et42 (+/- 2mm). However, if you do run 245/275, then you can run lower offsets that specified above by about 3mm.

I am already decided on the sizes above. Need to know what offsets I need to run based on that information. I get different answers depending on who I talk to or what website I research.

et35 front, not lower than et38 rear

Anyone have pics of similar setup as a point of reference? I have messed up and ordered the wrong offset before base off "internet advice". No offense, just verifying. :-)

This is my setup, i kinda did my own thing as far as tire size but it worked out for me.

19x8.5 et32 - 235/40/19

19x9.5 et42 - 265/35/19

Ok went back and checked measurements.

245/35/19 F
285/30/19 R

Both are 1mm taller diameter than stock. Closest match to stock circumference I can find.

Any pics of that setup? I am not wanting to decrease my front tire width, but the ET is where I am having difficulty honestly.

Alright I am doing 245 up front and 275 on the back after looking at the price difference for the extra 10mm out back.

ET35 front
ET42 rear

Ended up with +42mm Front and +47mm rear - with 19x8.5F and 19x9.5R
