Hello together, I would like to buy rims for my polo soon and would like to know how to calculate the right ET for the rims. As an exit situation I would like to use the rim size from the thread:. Wheel size: 7×17 Pressing depth: 46 If I want to mount a rim in the size 7.5×17 now, which ET would be necessary so that I don’t have to install distance discs? Statement from the above thread: Quote: Original written by Castro67 What do I nic now? if the rim widens and the ET moves outwards by 2mm, the spokes of the rim would have to stand outwards by a total of 0.25″-2mm or (seen from the middle)? Thus the spokes of the brake system are also outwards around this approx. 4mm. Where is my mistake of thought? Something I have not yet understood quite correctly.
