This is how you make alloy wheels out of steelies, the DIY way
I do not recommend you making them and using them on your car....
The last time Youtube channel Garage 54 did something crazy with wheels it ended up replacing wheels with man hole covers. This time it showed us an affordable alternate to expensive aftermarket alloy wheels. They replicated a Vossen wheel.
The process was quite simple. They took a regular steelie, cut 5 holes in the wheel's inner and added 5 spokes in its place and welded them into the steelie. Then they got rid of the rest of the steelies inner. The remainder is painted in black and silver for looking good. NOTE: to get proper proportions math was required, if you are bad at it, you will probably get a bad wheel.

Once the wheel is completed it is then matched to its tyre and then taken to the balancing machine. Once all the adjustments are made, it is fitted on a Mercedes-Benz 190 (I think the model is the 190, looks like it) for real life testing. From appearances it looks good on the car.
Well the guys from Garage 54 did test it at low speeds. I find it amazing that these wheels look very attractive. However, do not drive on rims like this, do not take risks like this, these blokes are pros they know what they are doing. Under the worst case scenario you do make them, do it with proper equipment (incl. safety) only for bragging rights and never use them on a car. Remember, I am saying if you do make one do it with proper equipment and never use them on a car. Enjoy the video...
