Since putting in the MS rear end with limited slip diff, I experienced bad tire wear with Open Country M\T's and with Wild Country XTX sport2. I have only done street driving, sad to say that, but after about 7k miles, both were\are at half tread or less. Fronts look brand new. the mt's were 255\85\16 and the xtx are 285\75\16. Les Schwab has no idea what's wrong because the wear is even on both sides. No cupping or anything. Oh, I do have a 6 degree shim under the springs too as I put in an add a leaf. Anyone else run into this?
