All E70(2007 to 2013) Rims will be a direct swap with two exceptions listed above.
- X5m rims will require modification to fit.
- TPMS sensors will need to be replaced depending on the year the 20" rims came off of.

One more comment about going to the 20" rim, I believe they will stick outside the fenders with out the flares which comes with factory 20" wheels. The 255's on the 18/19's are much narrower compared to the 275/315 that the 20" use. I know the wifes X5 looks funny when she has her 255/19" winters on. I have not seen the 20's with non 20" fender flares.

They will not stick out of the non-flared wheel wells the 20" will be pretty much flush with the fender.

The fronts didn't stick out on mine but the rears I thought did. I put the fender flares on and the mud flaps to match. I wouldn't have put the mud flaps on if I didn't tow a boat because I think they rear ones are just to wide. Most if not all the E70's I see here with 20's have the fender flares.
