Absolutely Sodo, several areas of risk mitigation going on there.

0to60, spot on -- and fear of failure with anything so vital as tires is one great motivator to err on the safe side -- whether justified or not.

Why does the tread look melted?

I'd suspect under-inflated or otherwise it got really hot, even once, to blow a sidewall like that.

If not verifiably caused from heat or other operator error, for me personally there's no way I'd trust another one.

Sorry, but for my safety that's just not acceptable.

Glad you dodged a bullet, though Jim!

Where are you getting this 80% nitrogen? I can only find 78% in my area.

Nitrogen in tires is just another sales pitch that solve problems that do not exist. Tires wear out because of use or time. I have never seen one wear inside out. Its from the outside in.

From the report: Effects of Nitrogen Inflationn on Tire Aging and Performance

http://www.branick.com/Nitrogen%20-%20What%20you%2...0Study.pdf


"The overall conclusion of the study is: When N2 is used as the inflation media, the change in rubber properties is significantly slowed down or even halted. From a practical standpoint it is important to note that the presence of 1 atmosphere of air in the 96% nitrogen inflated tires did not significantly affect the results, as compared to the 99.9% nitrogen inflated tire. This is important for the average consumer because the need to purge existing tires completely of air before filling with nitrogen may not be necessary. Another conclusion is that the oxidation of the steel belt rubber is truly driven from the contained air pressure inside a normal passenger or light truck tire. The skim region may be oxidized slightly from outside the tire when filled nitrogen, but the
rate of degradation is significantly lower than when the tire is filled with air. The wedge rubber, on the other hand, is in a sufficiently thick part of the tire, and is not nearly as susceptible to oxidation from the outside. The converse of this conclusion, therefore, is that oxidative aging can be accelerated by the use of oxygen enriched filling gases in the tire cavity without changing the mechanism of degradation in the tires internal components."

Great info WT, Thank You.

The six years comes from the auto industry, since they don't have a stake in the rubber business

The tire industry consensus seems to be inspect annually after 5, out of service no longer than 10 years from date of manufacture. Of course, damage or tread wear can take out a tire well before this.

There is no reason to throw out 6 year old tires purely on clock

Yep.

I think the real question is "Six years of what, where, how used, etc.?"

It seems logical to presume some worst-case scenarios were used when determining when a tire becomes unsafe... not to mention brand and quality.
