BTW that’s the original spare tire with the blue coating still on the “Tiger Paw” lettering.
Do not use that spare tire! it doesn't matter how nice it looks it is still a 25 year old tire and it will come apart. I would simply replace it before you need it.
I had my Burbs original spare in perfect shape on the Burb when my wife was driving one of our daughters to a baseball game from our cottage...
halfway there the tire looses its tread and it rips off all the rear AC and coolant lines, spewing coolant and refrigerant all over the hot exhaust..... it also just destroyed all the sheet metal back there.
without a spare in the truck, without an extra vehicle and being far away from home, I called everyone I could think that might have one of these tires and nope.... they all drive new vehicles.
A buddy lent me his car and I was finally able to get to my wife and meet the tire guy...
she was on the side of the road for about 2 hours AND not one damn person stopped to help her!
it cost me $200 to have a tire shop replace the tire on the side of the road.
YEAH.... get rid of that old spare before it creates a headache for you.
