My Uncle drove a government issued Jeep in Europe
Since you don't run the MTs in the winter, the cost is the same. I buy from my local tire shop and they do the change overs, twice a year, for free. Even if you lack space to store winter tires lots of retailers will store your out of season tires.if you can't afford to buy or store multiple sets of tires
The "I can't afford them" is not a thing. The cost per mile is the same.
