Spot on at what spec? There is a wide margin for toe in. My 11 had the same problem and actually both sides were wearing actually the outer edge was "stepping". Chrysler checked the alignment and they did not bother telling me they did not touch it! So more tire wear later I took it to a Frame and Axle guy I have been dealing with for over 30 years. He said Factory is up to 1/4" toe in so they can keep the truck tracking straight down the highway. He set mine to 1/32" toe in. Not too long after I switched to MS2's because the POS General's went bad and the fronts of the MS2's wore well after. All I did was rotate side to side on the fronts every 10-15K from then on. Here is the front MS2 with 40K on it.
