I have a first generation X3.
I have an extra set of wheels with snow tires mounted on them.
Will these wheels fit the new X3?

[roders]

Yes they will.

[Garax]

Are you sure? I heard that old X3 wheels wont fit the F25..does the old X3 have the 5/120 setup?

My E83 doesn't have TPM transmitters it uses the ABS/traction control sensors.

The specifications for the X3(F25) are:

Bolt Circle: 5X120mm
Offset: 45mm
Hub centering ring: 72.47mm
However, the lug bolts are different.
The F25 uses M14x1.25 bolts, while the E83 uses M14x1.5 bolts. (Both use 17mm hex heads and straight taper seats)
Trying to use the lug bolts from a E83 could damage your hubs.

Also the TPM transmitters use different frequencies, so TPM transmitters on wheels from a E83 will NOT work on a F25.

Lotus what is the implication on, handling, tyre wear etc on using the following after-market wheel on the F25

FRONT SPEC: 17x8.0" ET40
REAR SPEC: 17x8.0" ET30

OR

FRONT SPEC: 18x8.5" ET40
REAR SPEC: 18x8.5" ET30

This brings up another question. What are the implications if the mounted tires are out of size spec to the idrive system?

[northX3]

with the same offset, +0.5" on wheel width wouldn't change a lot the driving behaviour. the wheel would stick +0.25" farther outside. the added weight is the only thing that MAY be perceptible, assuming you're having the same tire width on both setups.

concerning 17" vs 18", there is no difference assuming you're having the same overall tire diameter

On the iDrive system, there is no problem, if the 4 tires have the same overall diameter, and that the TPMS is well placed. on the xDrive system, no problem, with the same conditions. the speedometer and odometer will be off, though.

sorry, should have been Xdrive

What do you mean by this?

[northX3]

8.5" width wheels MAY be heavier than 8" wheels

We're splitting hair here... Generally speaking, heavier wheels will add unsprung weight to the car, and may feel bloatier/more boat-like for extreme sizes (like if you were adding 10.5" width wheels, with +15lbs at each corner of weight to move through tight curbs)

I don't think there will be much difference going from 8.5 to 8.0, especially since the offset (ET) is the same

Lotus, just to be sure here. If I use the bolts from the F25 on the E83 wheels everything should be in order, is that correct?

Gonna bring this thing back from the dead. Is the inverse true? Will F25 wheels work on an E83 using E83 lugs? ie, a set of 19" F25 X3 M-Package wheels with 275 rear/245 fronts?
