Rim spec question??

[Denly]

I know this is dumb, but bare with me.

Will a this rim

8JX18 ET47 5X120 M12X1.5 72.6

fit in a car with OEM spec of

8JX18 ET53 5X120 M14X1.5 72.6

I know nothing about rim as I have never buy a non-oem rim in the past. I am wondering if my bimmer rim(1st one) will fit into my frd's Land rover. Rover ask for 255/60/18 tires.

ET47 vs. ET53 is the offset - you probably don't want to go smaller (or bigger? I forget how this works) but 5mm one way or the other is usually alright and you can get spacers if you need to.

M12x1.5 vs. M14x1.5 concerns me more, since the smaller holes may not fit right over the lugs on the other car. Have you tried to see if the wheel fits?

I don't have a floor jack with enough clearance to lift the rover, not that I want to trust my driveway can support a 6000lb monster either.

As @dave_the_nerd stated, a wheel designed for an M12 lug will not fit Correctly over an M14 lug. The offset is also higher on the other wheels, but some 5mm aluminum wheel spacers would cost you $50 for a set of 4.

I think the lugs are gonna prevent you from using those wheels.

Well... you can replace lugs too... but now you're talking work.

Certainly fair point. I imagine that's some fabricating shop or wheel shop that could lathe a M14 lug stud that reduces to M12 after a couple of inches. I'm not sure if I'd trust said setup, especially if I was off-roading with said Rover, but I guess the only thing preventing that from working would be money and time.

I had to dig around, but there is an aftermarket company that people driving Mini's seem to trust that makes a M14 to M12 conversion lug stud. $90 to get 16 studs (not including lug nuts). http://www.waymotorworks.com/m14-to-m12-stud-conversion-kit.html

Alternatively, a wheel shop might be able to safely bore the M12 lug holes to M14. Note this must be a proper wheel shop. Just running a drill through the holes without making sure that the holes are perfectly perpendicular + scoring from a drill will cause stress risers.

If I just had to use the M12 wheels on my vehicle, about the only route I'd consider is the M14 to M12 conversion lug studs + 5mm hub centric wheel spacers to get the offset within 1mm. That's about $150 in parts to get those wheels on there, but if I had to have them, that's about the only way I'd drive around on it.

No, they won't fit.

I'd be REALLY worried about the following items until you confirmed that they were okay:

1. Load rating of the new wheel vs old wheel. Generally larger lugs are used because the axle weight is high.
2. Do the hub bores match? We can't tell this from the information provided. If not, can you get hub sleeves to match them?
3. Do you have the right fastener for the new wheels' lug sockets?

Those are just 'in general' points for wheel matching. I could never in good conscience suggest that you have a wheel's lug holes drilled or modified to fit a larger lug, or replacing 14mm lugs with 12mm lugs. There are unknowns in this situation that could result in a wheel failing.

I'm fairly certain that's the 72.6mm bore size mentioned on both wheels.

I thought so as well. Either way though, dont do it OP.
