Thanks for the post. If you don't mind I would like to add it to the xterra4x4.com mods list. I'll do all the formatting etc.
4-wheel parts did a terrible balance job on my SSR's. After getting nowhere with that shop I took my tires to Les Shuab and they were able to get them all balanced to "reasonable" for a MT.
From talking with the guys they mentioned being able to do a patch balance where they balance the tire before mounting it using some sort of material on the inside of the tire. After that they use normal weights to take care of any remaining inbalance.
I'm curious to hear what Interco does with your tire. One of the local 4-wheeling mail lists was having difficulty getting Interco to replace a bad tire.
