Mechanic says it is a rear wheel bearing going, is that plausible?

I'm not sure, it could be tire noise I guess, about 20,000 miles on the tires although they are my snow tires which I still need to switch out. I'd say I'm 90 percent that its engine noise rather than tires.

I have a 2003 LS 430 with about 125K miles. Over the past 2 months the noise in the cabin seems to be significantly increased. Its just a general engine hum/whine and i don't think there are any issues with the car just wondering if there is something that used to be dampening sound or insulating sound from the cabin that could be wearing out/getting old or perhaps broke in some way? Thanks.
