Is it wise to inflate tires to 110 percent of the recommended pressure?
Alan Paulding Plymouth, MA Inflating your tires to a higher pressure than the automaker’s recommendation can reduce heat buildup and decrease rolling resistance, resulting in slightly better fuel economy. But it can reduce the tire’s grip on the road and decrease ride comfort. Overinflating can also make the tread wear unevenly, shortening the life of the tire. For maximum performance and safety, keep your tires at the auto manufacturer’s recommended pressure, which is usually found on a placard in a doorjamb, not on the tire’s sidewall.
