I bought "new" Bridgestone tires for my wife's car. The tires were low profile and not a popular size. 3 of 4 had catastrophic pressure loss within 5000 miles, at three different occasions. The tire shop said they were run underinflated.
I check tires pressure regularly, but don' t record the numbers. After the last failure, I remembered, my local mechanic just did an oil change and tire rotation 200 miles prior to the failure. I called and asked what pressure did they use, and it was correct. I felt comfortable that the good tires should be able to maintain pressure for at least 200 miles. The tire shop would not budge on reimbursement or credit for new tires.
While I was removing the last "new" tire, I looked at the date code. The tires I was sold were 6 years old. I didn't feel it was Bridgestones fault for one of their dealers to sell old tire, but I felt Steve Shannon Tire and Auto should have provided replacement tires.
I didn't want to get into a pissing match with Steve Shannon Tire and Auto, but vowed to relay my bad experience with Steve Shannon Tire and Auto every chance I get. If anyone is ever in PA, I would avoid Steve Shannon Tire and Auto.
OP, sorry for the rant, but I don't recommend using old tires. I have another experience about a free unused motorcycle knobby tire given to me, that was 15 years old, but I'll save that for another time
