I’ve done it before as well, but in reality, the handling effects it produces can be replicated with other adjustments on the kart that don’t affect the consistency and heat of the tires.
If you needed more heat in the tires on one end of the kart, you could run aluminum wheels on that end, but my opinion would be that if you had that situation, there is a bigger fundamental balance issue at play that needs to be solved with actual chassis adjustments.
