X3 - replacing 17" alloys with 18" ones
I have a 2004 X3 2.0td. I love my car but have always hated the alloys on it. As it's time for me to replace all 4 tyres I thought I'd have a look around at 2nd hand BMW alloys (that I like). I currently have 17" BMW alloys but like 18" BMW alloys but don't know the first thing about whether or not they would fit. The 18" ones were removed from a E92 SE. Will they fit? Also the tyres I currently have are 235/55/17 on all 4 wheels. The ones I am looking at have 225/40/18 front tyres and 255/35/18 on the rear wheels. Will this combination be ok with an X3. I've had problems with replacing only 1 tyre after a blow out in the past due to the fact that the tread depths have been different, the cars rear wheels used to slip at the back end so I know I have to run 4 tyres with the same tread depths. These 2nd hand wheels and tyres have 5mm tread on all 4.
Appreciate someone telling me if the wheels will fit and if the tyre difference will be ok. Much appreciated.
