275 45 20s on style 87
 

I thought I got a great deal for style staggered 20 inch style 87 rims......plasti-dipped them in black and then realized the tires were wrong size. they guy told me they came off 2005 x5.....i just assumed everything tires would be right size.

tires are almost new ...tempting to leave them on ...would it be safe? would they look OK? the guy also told me they were genuine BMW..he said bmw markings were lost when he powder coated them ( light grey)... is there any way to figure out if these were OE?

so what do you experts have to say?

The tire size has nothing to do with the rim originality

Look on the inside of the spokes for markings
And ur tire should b 275/40/20 for the front and 315/35/20 at the rear 9.5 inch front width 10.5 inch rear rim width

And the markings are cast on the wheel and u cant lose them

+1.



Also my theory on the slightly bigger front tire would be it would mess around with the transfercase some.
Someone can correct me on that...

OE wheels with style 87 will have stamp said BMW right in front of the wheel .
Aftermarket will have a stamp said BWM .

so, they were powder coated light grey and then plasti-dipped black? is the inside part of the wheel coated too? you can see some marking on the inside - what do they say?

Ur right imo because the staggered setup is alrdy a tiny bit off, and then wrn u change the size it messes with it more

what size are the rear tires? post some pics

Ditto above...without knowing what size tires are mounted on the rear...we can't really give you a good answer as to the affect the 275/45/20 tires on the front will have. We need complete information for both front & rear since both axles have an affect on the various technologies (ABS/DSC/xDrive) that need them to be within the same general tolerence of 3% (+/-) ...and any tire size calculator will indicate that a 275/45/20 tire and 315/35/20 tire has a diameter variance that is GREATER than 3%.

And ditto about the markings on the wheels. The BMW initials as well as the BMW part nbr (last 7 digits) and other wheel specs are cast into the wheel (around the hub's front side surface) on the style 87 wheel. It would take a really thick coat of paint to cover that data to the point that it was totally smooth. If you don't see any BMW specific info around the hub...rest assured that they aren't orig BMW wheels. :cool:

275/45/20s on all 4.


I didnt see any markings anywhere...tires were already mounted through...
