I have 29" std. bushwheels on my Rans S7. They really are a little heavy for the gear - the spring gear on the S7 is just as happy to flex backward is it is vertically, so I sometimes get some shake on the gear after departing a rough strip. I have the heavy duty socket mod, so I'm not to worried about wear, but the custom HD gear that some have for the plane would be better. I think 26" airstreaks would be the best fit, like courierguy has, but hey...mine were a steal.
All that said - I sold my other tires. Its hard to imagine not having the capability of the bushwheels. As has been said by others, it opens up SOOO many places to you. The hardest part is just trying to keep off pavement to extend life, but you would be amazed at how many non-towered (and towered if they will let you) airports have suitable grass landing between runway/taxiway. I've only landed once on pavement in the last 8 months.
I also only lost maybe 5mph with them. I cruise 95mph at 4.2gal/hr
And they look cool
