So I went with the Mastercraft AXT2's in 32x11.5/15. I don't know if it was because the 31's were worn (still had tread) or what, but damn these things grip the wet roads. I only get worried when I see a deep puddle on the interstate doing 80. Turning left/right on wet pavement....I really have to make it spin loose unlike the 31's.
After my UPS shipment (223 wylde upper lol) gets here, I'll run out and take a few pics. I really like how it seems to fill the fender wells better also. The truck was only raised 1/2", but I can tell the difference when getting in.
