I know it doesn't necessarily answer the question, as OP noted that he is ok with keeping the all-seasons for the duration of their life, but...regarding long distance trips in general. If a trip is several hundred miles one way, I would absolutely not drive my own car, but rather rent. Especially if most of the trip is the driving with little time spent at the destination. Cost to rent is small. It saves wear and tear on your own vehicle. There is a risk of accidents, animal strikes, mechanical breakdown, tire punctures, etc that would be disastrous (financially and timewise) hundreds of miles away from home. With a rental, you get another vehicle and keep going. My approach is to rent a car I like (or can tolerate) and let the rental agency carry all that risk.
