When my tires are at that point in their lives I think about whether I will be taking any road trips. For local around town driving, I would run the tires longer. If I intended to do a substantial amount of highway driving I would replace them. A few years ago my tires were at that stage and my wife was driving from NY to SC, so we got new tires before she left. A car beside her on the interstate wiped out in rain due to hydroplaning, my wife maintained control. I am more concerned about high speed hydroplaning than a low speed blowout on a run to town.
Tire Dry Rot or Not
One of our vehicles has Michelin Defender tires with close to 50K miles on them. The tires are 6 years and 3 months old. Tread is 5 - 6 32nds. Since the car will be around longer than the useful life of the current tires I figured I would just replace them now. I'm also curious if any of the photos show dry rot. Dry rot photos online typically show tires with far worse but figured I would share here for some feedback.
