Hot August pavement puts tires through a serious workout, so small maintenance mistakes deserve more attention than they might get on a mild spring morning. Underinflation, worn tread, old rubber, and neglected damage can all create problems when tires spend hour after hour rolling across hot roads.
That does not mean every questionable tire will suddenly fail on the next trip to the grocery store. NHTSA emphasizes tire maintenance because proper inflation, tread checks, rotation, balancing, alignment, and attention to damage all contribute to tire safety. Add intense summer heat, a long highway drive, a heavily loaded vehicle, and pavement that feels like a skillet, and tire neglect becomes a particularly lousy gamble.
