2008 TL Uneven Tire Wear ( inside edge)

Hello! I own a proud owner of a 2008 TL with 187000 miles.
The inside tread block on the tires is worn out after 25000 miles.
Car does not pull to either side however there is a vibration from 50-85+.
Suspension is factory. The alignment shop told me to install a camber kit.
Does this make sense? Should I take it to another shop and have them check for worn suspension?
Any help would be appreciated!!

Thanks,

Matt
