Nine years ago I had Toyo Extensa tires installed on my 2010 Corolla. They have 30,000 miles on them. My mechanic says they are fine, there is no dry rot and I don't need to replace them. I have always believed that you can't know for sure with tires that old. My mechanic could make some money replacing them so I am confused.
You got 30,000 miles and they lasted nine years. But yeah, I'd put a new set on.I have always believed that you can't know for sure with tires that old.
They should be replaced. There may be interior deterioration that you can't detect from the outside. (I've had an old tire that "looked good" blow out on me at low speed.) It's not worth the risk.
All tires have a shelf life. I don't drive my 2017 Mustang much (it has 29k miles on the clock and I bought it when it was brand new), and I got some dry rot on the outside of its OEM tires. The tires lasted 6 years, which is basically par for the course, especially when the car is exposed to the elements. I got those same new tires because I like them and they were on sale at Tire Discounters. Replace the tires. It's not worth the risk of having blow-outs. You'll wind up having one heck of a bad day when it happens.
I just replaced 6 year old tires on my Civic. Plenty of thread left and not much of dry rot. However, I've been noticing lately that on wet roads they don't provide enough grip (spinning when taking off, etc.). Even though they don't show any cracks, the rubber is drying out and losing grip. I figured I'd rather be safe than sorry so I went ahead and put new tires before the winter.
