Just before the winter found a nail in one of our all seasons. Un repairable. At the time the solution was to swap to winters a tad early. Now I'm wondering if I need to buy 2 new tires or if I can get away with just 1. They only have 2 summers on them, not sure the mileage because it's just a family vehicle, not a commuter or anything.

This can be tricky depending on the car, tire and amount of tread left. Is the vehicle AWD as if that's the case you may have to replace the pair or all four depending on manufacturer recommendations. If your existing tires are around 25-30% worn you may be okay on a 2WD car but you should check to see what the manufacturer of the car may recommend. If it's say FWD you would at the very least want to ensure you pair the new tire with the tire left with the most tread left.
