I talked this over with the Pit Bull guys - and I think the Hummer double beadlocks will let me run them at 1-2psi and really break in the sidewalls to get them pliable enough to really flex well on the trail.I don't think you'll like the Rockers as much as the SX's. Maybe with a heavier vehicle they work good, but the light rigs I've seen running them don't get any carcass flex. FWIW.
I run the 37x13.5 Rockers on my 86 flatbed Toyota. It comes in @ 4100 lbs trailready. I run the Rockers @ ~ 5psi and they bite incredibly well. My rig is fairly light, especially the back half. That team Webster Toyota p/u truck runs them with alot of success and that is a light rig as well.I don't think you'll like the Rockers as much as the SX's.

Just thought I would throw in a little update.
My 4runner has been sadly neglected since last October, and hasn't been on the trail at all in 2007
I was at a crossroads and considering building another truck or full tube rig that I wasn't worried about bashing all this sheet metal. So I have spent the last year or so collecting a LOT of part to be able to go a few different directions, depending on what I decide. In the mean time - I picked up a couple of 4x4 ATV's for the wife and I and we've been riding those to keep me thinking of the trails :cool2:
Anyway, I guess I've decided to keep the 4Runner and start working on it again.
As of Saturday, I picked up a set of 39.5" Pit Bull Rockers to go on it. I've wanted a set of these tires since they came out, so I finally broke down :laughing:
Problem is - these are MUCH larger than the 38" SX's on there now, and I am thinking my previously uncut fenders aren't gonna get to remain uncut for very long. Once the tires are on - we'll see what has to get modified to make them fit.
I also have a few other things planned, but I'll wait until there are pics to bring those up.
Yeah they do get taller, and much wider - that was my experience as well w/ the 37s.DRM wait till you blow air in those PBR's they kinda blow up. My 37's were bigger than my 38.5 SX's. On my light rig they worked awesome. Way better than my current Irok's.
Post some pics of them PBR's when mounted and take some measurements overall width and height and rim width. The 16.5 wide scared me a bit before but I think I'm going back to PBR's.
Call Cory @ toyotafiberglass.com. He'll give you some good thoughts about the strength of HIS 'glass vs trees (has a nice hammer demo). His stuff is all hand laid, not blown, so it's very strong.Considering what my plans might just involve - a little trimmage on the front fenders will be the least of my worries :laughing:
But I have always liked 'glass fenders - it's just that the tight woods trails we wheel in generally result in lots of cracked fiberglass.
