2006 g35x inside front tire wear

[si2ki30]

I bought a 2006 g35x awd at 107k miles and the front tires were worn to crap and had some steering wobble during hard braking. Had an alignment done with the old front tires, wobble went away during braking. Put on a new set of tires, and started experiencing some humming noise over 50mph. Figured it was noisy tires. Now at 120k, I looked at the front tires for the first time in a long time, and both tires are worn down to the belts on the inside edge. They look as badly worn and in the same place as the original tires at 107k

Which parts of the suspension could be so worn on both sides to cause the same inner wear pattern on the tires?

Just trying to understand what parts to check - nothing appears loose and car drives perfectly straight with no wobble during driving or braking.

That's definitely a camber problem, but there could also be a toe issue along with it. Feel for "cupping" or "scalloping" across the tire, if it's present then you're likely toed-out along with cambered-negative. Along with worn parts, minus camber can come from anything that makes the car squat. Weak springs, for instance. Toe is always adjustable, but most Nissan/Infiniti models don't have adjustable camber. However, on most of them with traditional McPherson or wishbone-upper suspensions (your G has the latter), camber adjustment can be added on by way of eccentric bolts on the control arms.
