Set of two Schwalbe Marathon Plus tour 700c x 40 tires. These are incredibly durable tires for commuting and touring. The puncture proof strip on these tires resists any puncture short of a nail-gun. https://www.schwalbe.com/en/tour-reader/marathon-plus-tour.html.
Cost about $60 or more each. Here are two for $25. Used but in really good shape with lots of tread left and rubber still soft.
