I'm sure both are pretty stiff but anyone have any comparisons on them.

My wheels have been at my mechanics shop for quite some time now but they are finally mounted. Never a problem with just the tires but I added TPM (tire pressure sensors) onto the wheels and he was having quite a hoot getting the tire on safely without damaging the wheels and then getting it past the sensor........

I'm picking the wheels up tomorrow and I'd be curious to hear his story on how much of a b!$ch it was
