Just wanted to let you guys now that I've installed new tires on my rig, I'm now running on 37s, they are MTRs mounted on 15x10 Black rockcrawler wheels. I've always wanted to test the limits of our IFS. I will let you all know how it performs offroad, So far I've driven it on the road and have notice a bit difference on the RPM in comparison to the 35s, I now cruise @70MPH around 2800 RPM which is not too bad but perhaphs I might feel the difference more going up hill...we'll see!
anyway, here is a picture of my truck on 35s:

And here are some on 37s:
BTW, I have not cranked my torsion bars yet!
