Bush Wheels Radials vs non radial

Looking to purshase some Bush wheels just can't decide between the radial or non radial versions and especially now that there are radials in all three sizes. Just looking for some input as far as radial ve non or even 26 vs 29 vs 31

thanx

We have logged 200+ concrete landings on the 31" bushwheel radials and they are holding up excellent.

Let me just say that these tires have caused more airport conversation than a gear up landing (we have a lot of those, so they are kinda boring).
