By the Numbers: Tire Replacement at Davis Automotive Repair in Centennial

Ever notice that your tire is covered with writing? It's like some hieroglyphic art form. Of course, Centennial drivers know that it's not just graffiti, but to most of us, it might as well be. Would you like to know what all those codes on your tire mean? It won't lead you to buried treasure, but it could help you make a better tire purchase at your local Centennial tire store.Prominently featured on your tire is a set of numbers and letters that looks something like this: 225 50 R 16 92 H. The first number is the width of the tire in millimeters, or the width between the sidewalls of the tire when it is fully inflated and not carrying a load. When Centennial drivers replace tires, they need to match this width number, or the tires won't fit properly in the wheel wells.The 50 is the aspect ratio of the tire, which is measured by taking the height of the sidewalls and dividing it by the tread width.

Which is slipperier, a pile of pencils or a pile of marbles?Synthetic motor oil lubricates better because there's less friction. This results in myriad benefits: better wear protection, cooler operating temperatures, more power and better fuel economy. And synthetic oil doesn't sludge up like conventional oil so it prevents those small oil passages from clogging up. (We see that too often at Davis Automotive Repair in Centennial.)Some manufacturers are extend ... read more

Technicians at a service center such as Davis Automotive Repair in Centennial can scan the engine's computer for ... read more
