I've got 205/50/15's on 6 inch wheels on my PV, and the steering is barely heavier than with the 165R15's on stock wheels. Of course, it's a bit heavy both ways, but with long experience driving non-PS cars (including some pretty big old 50's trucks) I just never turn the wheel much with the car at an absolute stop. Even rolling as little as an inch or two makes turning lock to lock half the effort.
