By "technology advancements", I meant better tighter molding and better plastics making cars stronger lighter. Also the use of titanium and fiber is making things lighter. Yes the size of the tire would be an option, but the width does affect how long they last so I don't quite agree with you there. Wider tires equal more contact with the ground putting the driver in better control of his equipment. Remember THE ONLY THING TOUCHING THE GROUND IS YOUR TIRES. If you have more traction and better control, driving will be easier, and we all know the newbies need all the control they can get. LOL.
