Likely due to the increased power needed to spin the smaller drums..
Check out Kreitlers wattage chart- not necessarily accurate- but will give you an idea of the differences between 3" and 4" drums.

for me, putting resistance on your 4.5" rollers is counterintuitive, the whole reason 4.5's are great is because the resistance is lowered and you can focus on your spin..
best option for resistance training is a Turbo Trainer..
i guess second would be 3" rollers with resistance ridden on a road bike- so you can dial in the effort with the gears..
