Need advise and help on Wheels/tires...

[blaCkwinD]

Hi everyone, I have a 2006 x3 M-sport package. Need new tires soon, I am planning to replace them all which gonna cost around $250 -$300each.. My current wheel look just like the picture below


But i found a good deal on X6 wheels going around $2000.. The owner bought the car and took them off. Its BMW X6 E71 19" Start Spoke 232... As far as i can pull some info from the seller, he claims its ET:48 and ET:18 and 9J x 19 ( Not sure what exactly it means).


Can someone help me to verifies wether this set of wheels fit my x3? or Do i need any spacer to fit it?

THanks
