Pretty sure that front tires on all vehicles wear faster that rears...
(assuming proper alignment and tire pressure on all tires)
due to their function in turning... the front wheels initiate the turn...
when the wheel turns there is friction and a resultant force at an angle to
the direction of travel.. result is more wear on front tires....
