Does anybody know the size of the OEM steering wheel? I could not for the life of me find that info anywhere online.

Trying to vidsualize how much smaller a 350mm or 330mm wheel would be

Get a cardboard box, string, pencil, pin.
Measure 175mm of string, tie to pencil. Put pin in middle of box. Tie pencil to pin. Draw perfect circle with pencil. Cut out shape. Should be 350mm.

Place over steering wheel. :D

For some reason your question reminded me of those kid shows and geometry! But I got spare wheel in the garage, I'll see about measuring.

I just went and checked. I measured the outside of the wheel and it was about 368mm roughly on the outside of the the wheel so 350mm does sound right if going between the insides of the wheel

Was not expecting that

I find the OEM wheels to be just a bit big. So I guess that 330mm wheel I've been eying online might not be as small as I thought it would be.

Still want to wrap my hands around one first, but still this is good to know

@Vertex beat me to it! :)
This is my Rexpeed wheel which measures 14.5" or 368.3mm
My OEM Supra wheel was about 14.31" or 363.5mm

Assuming the wheel you are looking at is usingO.D. (outer diameter), 330mm is a solid inch and a half smaller. It'll feel pretty good for a track car.

But for a daily, may reduce your view of your gauges by a bit for daily driving.

Yea I was bored and at work. Grabbed one of the techs tape measurer and walked out and check since I drove it today. Measured about 14.5 inches like you said yours did so just converted it to mm which was about 368

That's what you get a quick release for, no?

I've got it all figured out. Driving down the highway with my 330mm wheel. Need to look at my gauges. Oh no can't see! Pop the wheel off. Hold the revs steady so I don't accidentally impale myself. Check. Pop the wheel back in.
