If someone is a pretty casual rider that's not putting in too many miles annually, sure - change out a tire after a handful of years when it's looking sad and dried out. If you ride a decent amount, though, making a habit out of throwing away a tire that has potentially thousands of miles left is going to increase your consumables budget considerably.

Of course he's not going to die, but suffering an incovenience of walking a couple of miles or being late
for a planned activity after riding comuld happen due to worn tires. My time is valuable.
