Why a relative replaced some perfectly good Michelin Tires?
So if a shop sells a set of new tires that were manufactured five years ago, does the purchaser drive around the block once and purchase another set freshly manufactured tires, or does the purchaser drive around on the "new" five year old tires for five more years and then look for a new set? This is getting confusing.
I've posted this in other threads, but all the same, there is a sound reason for this. A tire
that passes 6yrs. old & then is sold will have an "average mileage" life expectancy that will
exceed the safe operating window of the polymers that it is constructed of, hence at that point
they don't want them to be sold. It's like everything else, operating/storage conditions and
driver habits can decrease the life a perfectly good fresh tire, most of us wear them out long
before they degrade. However, there are a lot of different brands that have shown a high amt.
of breakdown per mileage & time recently, formulae differ tire mfr.& model/line within as well.
As far as vehicle codes go, every state is different, and I can tell You for a fact it's not always
up to speed, relevant, or even informed sometimes. Sometimes the rules are changed just
based on the amount of complaining from constituents rather than studies, science, or facts.
Rusty rotors, cracked windshields, window tint, rusted brake lines, blown-out protective boots
of all types, etc., etc., have all been revised repeatedly mostly based on complaints, nothing
else.....................................
