I lived in Dallas at the time. Sometimes in the summer the temp could get up to 3 digits. Once you got out of the city, there were long stretches of semi-deserted highway, just begging for you to hit the gas pedal. I didn’t think it was worth the trouble to get the new tires, but my hubby seemed to think it was important. I procrastinated so much that he took my truck in himself.
It was about that time that I was doing a lot of driving down to Newport, RI (about 70 miles) for work. I’d leave early and average about 75 on I-495 without any problems but the last time we saw three digits hereabouts was when Edsel was a boy.
Other than whether or not is was worth the trouble, tires with 60k are at the end of their economic life. Ford did not pro-rate the swap, it was outright new tires for free.
BTW, good on your husband, I do the same thing with recalls on my wife’s car. I guess I value her life more than she does.
