Seeking opinions, space saver wheel.

[sapphireblack]

Most X6 owners will know, courtesy of BMWs use of different wheel hub sizes front and rear, any space saver wheel is a compromise. According to realoem, BMW offer an 18" steel rim with an offset of 14 and a 19" alloy, offset not specified

Currently i have the 18" option under the boot floor. Its never been needed and hopefully it will stay that way, preparedness is never a bad thing though.

As usual selling stuff is never easy so i got to thinking i should perhaps make use of the surplus alloy space saver I have for sale here. But then it gets tricky as this wheel has an offset of 40 and a 72.6 CB so would only fit the rear axle.

Adjustment is necessary.

1: Buy a pair (no one sells singles) of 25mm spacers that step the CB 74.1>72.6 so it will fit both axles and adjusts the offset simultaneously. One spacer would be completely wasted though.

Or.

2: Have the alloy space saver CB enlarged but knowing the offset, 40 vs 14 is still rather shallow, the rear is depicted here

Costs are much the same, £50 for engineering or a pair of spacers.

Simplest option, forget all of this, just keep the steel wheel and sell the alloy for whatever it may fetch on an auction site

Why BMW made things so tricky we will never know and no logical reason.
