4 ohms wears tubes faster ?

Assuming one is running a 4 ohm load (either a single 4 ohm cab, two 8 ohm cabs, or even four 16 ohm cabs paralleled down to 4) and the amp is set accordingly to 4 ohms, does this place more stress on the tubes and wear them faster ?

If so, could one then assume a matched (amp set to 8 into an 8 ohm cab) setting of 8 ohms wears tubes faster than a matched 16 ohm settting ?

No. If the impendance is set correct it makes no differance on the tube wear.
