They do exert more lateral load on the wheel bearings but fortunately you have a cruiser and everything is over built, therefore you can run them a long time before you notice anything. If you ever do.
I have ran a spacer on mine since i got it the offset on my rims put them a little too close to the tie rod end. 1/4" works out perfect for me and i have never had any problems. Just make sure that you have enough thread on your lugs mine ended up being a little shorter than I would like. I ran the hell out of it and they are still good.
