So Im currently running stock 19inch 5-Star Rims on my Q5 with winter tires. I have 12.5mm spacer in the front and 20mm in the rear. I want to get the Hartmann HS5-209-GA:M 19" but not sure what off-set I should get, the +25 or +35. If I get the +25 would I need the spacers? Would they sit flush? Anyone else have these rims? Thanks.

You'll have poke in the front if you do the 25s all the way around. Back would be perfect without spacers.

Your current offset is 26.5 mm front and 19 mm rear (stock wheels are 19x8 ET39) So front offset will be very similar with ET25.

However, going from 8" to 8.5" wheel will increase tire total width by approximately 5 mm (or 2.5 mm on each side).

So in the end, outer side of front tire will be approximately 26.5 - 25.0 + 2.5 = 4 mm closer to fender. -3.5 mm for the rear.

Try this tool out. Gives you the difference on the inside and outside of two different wheels.
