New style FJ's and 37" KM2's. 
At first sight, (rolling off the UPS truck), I was kinda freaked out as they looked huge. I knew from past experience though, that they would "shrink" once under they truck; and they did. Here are a couple of comparison pics with the 315's. It's not near the "leap" I was freaked out over. They don't really feel different power wise (on pavement anyway). They do provide a smoother ride on pavement as well. I put the truck in low range and noticed that the crawl ratio does noticeably suffer. We'll see about gears one of these days. Going to head up to Disney tomorrow and test them out. I'll report back with the results.
I centered the 315 on top of the 37" in an attempt to show the true diameter difference and it's not really that different. If you're on the fence, I say go for it.
