This may be more than just a wheel thicker than your used to. Are you holding on to tight? It’s an actual real possibility. Is the car relatively new to you? Are you 100% relaxed when driving it? I have found myself more tense when driving any car new to me until I become used to it.
On your next few commutes try to be aware of your arm and body tension. If you noticed it’s high, breath and consciously relax your arms. When I started track driving years ago I had a great instructor who immediately picked up on my upper body tension and my ‘vice grip’ on the wheel. My hands/arms were a mess at the end of a track weekend. As my skill level progressed over time and more importantly my awareness of my own body tension this completely disappeared.
I’ve experienced the same ‘hanging on to tight’ issue initially with new aircraft I’ve flown and new motorcycles I’ve ridden. Conscious awareness of it for me worked as a fix. Maybe worth a try before modifying the wheel?
If your set on wheel modification these guys may be able to help. Doesn’t have to be carbon fiber. They could probably do the wheel any way you want it:
