Need some advice...I have a death wobble that happens when I hit a pot hole/bump/pebble in the road at between 40-50 mph. I know this is usually due to the tires not wearing correctly. They tires are only about a year old (~15000 miles) and I have made sure to rotate them every 3000-5000 miles, but they still seem to not wear correctly. Any ideas on what is causing the odd wear? Any ideas on where I can take it to have it looked at by someone who would know what to look for (Denver area)? I hate using a dealership for these kinds of things. Thanks for the help.
