It is vital to maintain proper tire inflation pressures for 2005 Cadillac STS tires. Low tire pressure will result in tire underinflation while high tire pressure will result in tire overinflation, which can decrease fuel efficiency, lead to uneven tire tread wear and reduce tire life, compromise tire safety and cause tire blowout. Check 2005 Cadillac STS tire pressure regularly, and monitor 2005 Cadillac STS tire inflation pressures to avoid driving with overinflated or underinflated tires.
