How to get rid of inside tire wear comes up fairly frequently. I know there are many owners that go outside alignment specs to eliminate the wear. I always cringe as I think it is a safety issue, especially with a daily driver. Even though you are not concerned with handling I wouldn't go past the minimum specs.
