Drive tires inner edge wear

Need help to figure it out, All 4 inner drive tires recently started showing just the very inside edge wear, other then that all tires look wearing uniformly with about 9/32 left on them.Those are original tires on 2014 volvo vnl with 260k miles. In the last 6 month truck had been 3 axles aligned, all shocks replaced, and a few weeks ago leveling valve replaced did not see any funny wear at that time. Thanks

 

Thanks for your inputs, Will start with checking wheel bearings it just seems odd that all 4 wheel bearing went out of specs at the same time. but i guess it is possible that they were not set right from the factory. Have to have it fixed before i invest 4k on a new drives. Will keep you guys updated
