Driving around on underinflated tires is just a bad idea all the way around. Underinflated tires increase a car’s rolling resistance, meaning a drop in fuel efficiency since it takes more energy to move the vehicle down the road.
A single tire that’s down by ten pounds of air means a 3.3 percent drop in fuel economy…multiply that by all four tires, and you can figure on giving up ten percent of your gas mileage. The added friction and rolling resistance also means more heat is generated, and heat is the enemy of the internal structure of a tire. That heat will damage a tire to the point of failure. Studies show that underinflated tires are a full 25 percent more likely to fail, and at least half of one-car accidents involve a tire problem as a factor. And still, it’s estimated ...[more]
Tire rotation is an easy maintenance item that has long term benefits for any vehicle. When properly maintained, tire rotations can improve fuel economy, extend tire life and provide drivers better handling through improved stability. Frequently servicing vehicles with tire rotations is imperative to sustaining tire tread by ensuring all tires are used evenly without excessive wear to one section or another.
Normal tread wear is unavoidable due to uneven vehicle weight dispersal, vehicle performance, etc. Without tire rotations, tires continue to wear on the same areas over and over, causing irreversible damage to tire tread which drastically decreases tire life. Engine weight accounts for a major portion of vehicle weight, causing front tires to wear significantly faster than back tires. Front tires also take all respon ...[more]
