TT Wear on one tire..only took few short trips

Jack it up and see if the wheel bearing is loose. Any recent servicing of the axles, new brakes or whatever? Look underneath and check if maybe the spring centering bolt broke. Do both sides look the same?
rub or strike a curb recently? Measure from a stationary point underneath to the center of the hub on each side. Same?
Measure center to center on each hub. Are the axles spaced the same?
