Stop in for a cup of coffee

I have never rotated my tires on my newer cars, i probably should.... my jeep is 6 years old and every tire is dryrotted already.. wtf is that...
Previous daily driver was bought in 10/06. 2010 needed tires so got snow tires. After they are on, the seller says "you know, not to use these above 40 degrees". Well, spring 2011, bought aluminum slots and stock replacement tires. Switched out every season. Regular tires cracked in 2021. SOO, snows are on the vehicle and doing fine. They do wear a little quicker, but man!, are they fun going round corners quick! They just started the harsh ride. All the cushy tread must be gone. To remedy this, bought new tires, and muffler and, oh wait, just got a whole new truck.
