For the Love of God and family! STOP!
If you have read the manufacturer's recommendations follow them!
If they recommend 5??? year's but warranty the casing 10, the 5??? Is the numbers to go by. THEY KNOW THE STATISTICS FOR THEIR TIRES. It's not an add to extract more of your life blood.
Ever wonder why the tires you buy are only a couple of weeks old? Those companies don't stock pile inventory, they only produce according to need. This means they fight all the time to keep up with demand. If people follow recommendations, they need to try harder. Any tire used past that date increases risk!
This is the thing!
If the price of admission is not in your budget, then don't borrow the money to see the show!
This is why I say that!
I Am a widower X2, the first loss 26 years ago, the second in 2022. I still wake up some mornings with less sleep than my head was on the pillow. I spent hours thinking of what I could have done for a different outcome. Truth is they passed on their terms, and nothing I could have done would have made a difference. If My choice was to have saved a buck,and I knew that was the case, I would never sleep knowing My actions were to blame.
Saving money for something so important as tires, is akin to a senior spending his/her pension at the casino to try and pay rent.
It really is that simple!
May your spirit guides direct your path!
