3 to 4 adapters

cubefx · 10-11-2008, 10:14 PM

I remember some discussions here that it is will be impossible to make adapter plates so we can use 4 holes rims.
Owner of this smart did it.
3 lugs(PCD 112) to 4 lugs(PCD 100)

There is a big selection of nice 4-100 rims.

Does it make a difference that it's a 450? Honest question... I don't know sqwat about that area of the car.

I might be wrong, but I believe it is the same bolt pattern 3x112 but different offset, so adapters would work.

Do you have a link to check the pricing? I believe the 3-5 lug is available for $300+ s/h so a better price would be appreciated.

Where did you get that photo?

I found this online a while ago and have photos stored on one of my drives. All I know that smart is 2003 pulse convertable and the owner is in Malaysia.

I would have serious doubts about running on the road with 3x112 to 4x100 adapters.
I ran the idea up in a CAD package years ago and it is far from safe.

Is it not safe due to the spacing, IE 100? I am not familar with the way these patterns go. But it would seem like an extra bolt to hold it on would be way better. Again, I have no clue how this hole pattern stuff works, but if you could enlighten me, I would appreciate it. Thanks.

On the 3 to 5 stud adapters, 1 of the bolts goes all the way through the wheel, the adapter and the hub.
On the 3 to 4, the adapter is bolted to the hub and the wheel is bolted to the adapter.
No matter how you arrange the bolt patterns, 1 of the 4x100 bolts sits too close to 1 of the 3x112 bolt heads meaning there isn't enough material around 1 of the bolts to allow it to be safe.

If it was viable, we would have seen them for sale years ago instead of the 3 to 5.

That has me wondering why did they (smart) choose to go with three in the first place. Did they really worry about weight that much or are they not so bright like so many of us seem to think.
