3SDM Rims fitment

Hey Guys,

I found some intoxicating wheels that I think would look breathtaking on our SL's.

They are called 3DSM 0.04..a few questions.. How do we fit a 73.1 bore on 66.6 bore?

The size is :
  • Size: 20x9" et25 20x10.5" et27 Does this fit and if so what tires fit?
http://www.urotuning.com/3SDM-0-04-W...4.112.20.s.htm

A video I saw on youtube, funny the scion is closer to our SL than the M6. Also I think the scion stretched his tires(not doing that)



I have an eye for these things and happy to share with others..

Thanks,
DG2

You can get bore centric rings that will adapt wheels to different center bore sizes, just stay away from plastic ones, they degrade over time.

I'll have to double check the offset on my Carlssons, I'm pretty sure they're the same widths as what you mentioned. I'm running 255/30 on the front and 295/30 on the rear with zero rubbing and no ESP warnings, I wager you should be able to do the same.

Try comparing the stock wheel specs to those and see what changes in an online calculator, should give you a good idea of whether they'll fit.

You front tires are 661 mm in diameter (correct size for our cars) and rears are 685 mm, which is too large. Apparently, it doesn't cause any problem with ESC and ABS, but your speedometer is showing speed about 4% lower than actual. Correct size with that setup would be 305/25 (exact match) or 295/25 (just 5.5 mm smaller than nominal) in the back.

25 sidewall is so thin..i'd be scared for the city with these potholes.

what other alternatives can I wear?

Currently stock 18 is 285/35.

So If I wanted a 285/295/30/20..would that mean I need a 255/265/35 up front?

It is easy to calculate. If D is your wheel diameter in inches (say 20"), W is your tire width (like 295), and R is you aspect ratio (like /30), then you calculate the total diameter of the tire as D*25.4 + 2*W*R. Front and rear need to be identical or, at least, really close.
