I need to get new tires for my stock 19 Ms but I am considering purchasing a wheelset from someone instead. Need some help confirming that this will be a good fit.
The standard specs for 20s on an F10 5 series looks to be:
Front: 20x9 ET35
Rear: 20x10 ET40
The wheels that I would be looking at purchasing has the following specs:
Front: 20x9 ET20 with 245-40R20 tires
Rear: 20x10 ET25 with 275-35R20 tires
If I am reading the image below on how offsets work, having a lower offset would mean that the wheels would sit closer to the edge of the fender producing a "flush" look. My question is...is -15 in the front and rear too aggressive of a reduction in offset? And do the tire specs seem good?
Do you guys see any major fitment issues with this?
And what does programming a TPMS entail? Is this something a BMW dealership has to do and if so, how much does that cost? I thought the vehicle would just recognize the TPMS system installed on the wheels as long as they are the right year. I believe this was for a 2009 750li and I have a 2011 550i
