I'm wondering if you all (with the short tire life) have checked your toe in lately? It should be "0" degrees. I find my car is VERY sensitive to toe in AND tire pressure. Also I run 28# in the fronts. My Avons are going on 4000 miles and look like new. My car is a 2012 and I check toe in, caster and camber (Empire Kit) once per year and I find slight changes in all, A simple test is can you push the car easily on the level with one hand?
