Anyone know what it is? For when looking at aftermarket wheels?

20" to be exact.

 

I run OEM/std 18 inch flute style wheels. The P.C.D (pitch circle diameter) is 5 x 120.65mm.Translated this means that the wheel has 5 bolt holes and the diameter of the imaginary circle through the bolt holes is 120.65mm.

Note that 5x 120.65mm equals 5x 4.75". Not to be confused with BMW 5x120mm. I personally decided not to ignore that difference when choosing wheels.

5x 4.75" is used on some American cars including Corvette and I've heard of people putting 120.65 wheels on 120 cars and vice versa.

Other compatibility details to beware of: wheel center hole too small for your car's hub, offset of outer and inner rim beads from hub (causing wheel or tire to rub on inboard or outboard sides of wheel well.

 

What do you guys think of just running 5x120 as there seems to be a lot more options of that size then 5x120.65?

 

Will this be a problem if I go with 5x120.65 instead of 5x120? Google has given me mixed reviews...

 

Those anyone know if there is a conversion kit ( spacer) from 120,60 jag to BMW 120.00.

 

Thanks.

 

I wouldn't bother... the difference between 120.65 VS 120 is .65MM (or ~0.0256 inches... that is ~1/40th of an inch). That has to be within the tolerance... and I have been running 120's on my car (that were on a bmw) for years with no problems. I would be more concerned with the hub bore and ensure that is perfect AND the offset.

 

Thank you for this information, I tried to slide the BMW rim over the jag bolts but it's to tight, I could drill the wholes out but not sure if that's the answer.

 

I use Bmw wheels on my Xkr 2000. They are TSW Chicane 5x120.65 20" wheels, 10" wide rear and 8.5" front. The center bore is somewhat larger compared to Jaguar Xk8 spec so a hub centric ring is needed. You have to be more careful when mounting the wheels to the car also otherwise they might get stuck on the wheel studs

 

I had my wheel off this weekend and it's a hub-centric mount, so it's the hub that carries the load, the hub diameter and hub opening need to match accurately, and the fit at the studs is less critical. Someday I'll try my BMW wheels on my XK8, but assuming the hub diameters differ, getting the correct hub centric ring is necessary.

 

You're right. As long as you have the wheel hub centric you should be fine. But if the wheel is not perfectly centered, wheel lug nuts will stuck and some will not even thread.

 

Ok, however the jag has a73 mm hub. And the BMW has a 70 mm hub, not sure how the hub centric ring will fit.

 

I run 20" "BMW" wheels, the lugs fit fine though the radius of the hubs on the new rims were less than half a millimeter too small. I just shaved them a bit with a router and they fit great and are still hub centric.

 

You will have to get the wheels bored out a tad to fit... I had contacted the manufacturer of my wheels and was assured there was plenty of room and girth that removing a few millimeters wouldn't be a problem (they would have done it for me if I was buying the wheels from them, but I had bought a used set). I think I paid $50/wheel to have the hub bore increased.

 

Thanks for all the advice I'm thinking ordering 4 custome made spacers, 4.75x 120mm with the right hubs. Does anyone knows a great company who will make them for me?
Appreciate your feed back
