Beware of old ST tires!!

[amxpress]

SO I'm driving down I-26 heading to Charleston for work when I come upon a Jayco fiver sitting along the road. I pulled over and found the owner removing the right front tire on the Jayco that had blown, the tread ripped off and took out the fender, damaged the undercarriage a bit, and scratched the side of the fiver. They were 15" Denman ST tires made in Mexico. I checked the build date. 4807. The tires were 5 1/2 years old. He said he recently had his mechanic install Nitrogen in all 5 tires. That didn't do much good. He was installing the spare and I stopped him. The tread was split on it.
I told him the tires were over 5 years old, he said the tread was still good. I looked at the right rear tire and it was dry cracked and under inflated. He called a tire shop to come out and install a new tire. In the mean time, I went to the next exit and brought him back a business card for a local truck tire shop.
Moral of the story. ST tires age. Don't trust them just because they have good tread. Installing Nitrogen in old tires is a waste of money. Find a trust worthy mechanic that would have found the tread splitting in his spare. Properly inflate your tires!!!
Not a good way to start a vacation. I hope he and his family have a good time in Charleston, and he gets 4 new tires!

Amen brother! I have Mission Tires mfg in 2007. The tread is good and like many folks, I thought I would try to get one more trip in before replacing the tires. The tread is good, but I was noticing some aging around the edge of the tire.

The alarm on my TPMS went on and indicated the right rear tire was rapidly deflating. I got pulled over okay without any damage. The tread was starting to seperate. I got the tire replaced with another Chinese ST tire.

Will be going home this Friday. Hopefully I'll get there without any tire failure??? When I'm home, all the remaining tires will be replaced with new ST tires. NO MORE trying to get in that last trip.

Thanks for the reminder to all AMXpress - I read so many times here that "the tires still look new" etc., etc., etc. With RV tires, you must not go by that but instead replace according to the code on the side. We've done that and have so far been safe. On our last RV, the tires were a couple of years from the code replacement but they showed crazing on the sidewalls so we replaced them. Our current tires are ST. We're full aware of the problems some have had but also aware of others that have driven safely before replacing by the recommended tire code.

All tires degrade with time. The NHTSA recommends more frequent inspection of all tires after 5 years due to degradation chiefly from ozone.

I agree. Before Denman went out of business they were a respected ST tire. Age on an ST tire is a major factor in failure.

If age is the major factor, why do so many fail in the first year? Chris

I agree. Before Denman went out of business they were a respected ST tire. Age on an ST tire is a major factor in failure.
