Back in the day I had 5 tractor trailer trucks. All our tires were bar coded for warranty issues. They could track each tire back to date of manufacture all the way up to the day it was sold. We also recorded the numbers and tracked how long each tire lasted. Believe it or not we could get 300,000 miles on drive tires. You tend to forget when and where you bought them after several years of running. So my guess is that these ugly white barcodes are your serial numbers for any future claims.

I agree. They should be on the inside. You should have to even ask that if you are a qualified installer.
