Hi everyone, I’m a total n00b to car ownership & maintenance. I ran over something yesterday that punctured one of my rear tires, and the AAA guy who just came to put my spare on doesn’t think it can be repaired. I’m going to ask my mechanic what he thinks, but in the meantime: if I do need to replace the tire, how the heck do I figure out which new one to buy? The car is a hand-me-down from my mom; she put on four new Kelly Charger GT tires in 2014 that are still in pretty good shape (other than this puncture). She says that since it’s a 4WD vehicle, I should replace two of the tires, not just this one. Is that right, or do I need to replace all four?
I do mostly city/suburban driving, minimal highway time. I’m in Philadelphia, so I do need to be able to drive in snow, but rain is much more of a concern. Do I need tires that say they’ll last 100,000 miles on the surface of Mars, or are the less expensive ones okay?
