3 old tires? Finally made it to a Walmart on the donut spare and they only had one tire in stock, so the car has 1 brand new tire and 3 tires that are four years old with 35k miles on them. Tire guy there said that’s ’fine,’ but internet is telling me otherwise.

Also…what’s the consensus on replacing a windshield with a 6 inch crack on the passenger side that almost starts at the edge?
