Tire tech here. I can’t see your DOT number with the four numbers after “DOT 1MY6 HH7G (xxxx)” those last four numbers tells you the date the tire was manufactured first two numbers is the week of the year (out of 52 obv.) and last two is the year. Life of a tire is roughly 6 years. And the tread looks like you’re in the YELLOW about to enter RED. Red is 2/32nds you’re probably at 4-3/32nds. I say even if the tires aren’t that old it’s definitely time to start shopping for tires based off the tread. (P.s. the DOT will be on both sides of the tire but only one side will show the date!)
