I hope you bought new tires for her!
Agreed, 10 years is really the reasonable max time to use tires for, even if they look great outside, who knows what the inside looks like. I have a set of General Grabber AT2s on my oldest Jeep that are turning 10 years old, they probably have like 20K miles at most on them, they look like new, no cracks but still. So probably will go with another set of those. This is the second set of the same tire that I got 10 years out of, I had them on my 2007 Grand Cheorkee as well.
