WONDERING WHY YOUR VALVE CAPS ARE GREEN?

BECAUSE YOUR TIRES HAVE BEEN FILLED WITH NITROGEN!

The benefits of nitrogen are listed below and this extra benefit is included at NO additional cost when you purchase or changeover your tires at Harper’s Tire. Don’t forget, Harper’s also has the latest and greatest tire mounting equipment, ROAD FORCE and  “ON THE CAR” balancers and we ALWAYS HAND TORQUE your wheel nuts to the manufacturers specifications.

 Nitrogen-filled tires use less fuel.  Everyone knows that properly inflated tires get better mileage. Tires filled with nitrogen maintain a constant pressure far longer than tires filled with compressed air. Since compressed air in a tire migrates outward through the tire casing and tire body, tires filled with air can lose 12 psi in six months, increasing rolling resistance and tire temperature, causing deterioration and weakening as air passes through the tire. Oxygen migrates through the tire four to six times faster than nitrogen. On the other hand, tires filled with nitrogen will maintain their optimum pressure much longer, thus reducing tire failures. Above all, tires that are properly inflated roll like they are supposed to roll and can save 2% to 4% in fuel costs. That’s a lot, at today’s fuel prices.

Nitrogen reduces tire failures.  Tire failures are most commonly caused by under-inflation which accelerates degradation of the tire casing. By inflating those tires with nitrogen instead of compressed air, you can increase tire life by as much as 25%.

Nitrogen runs cooler.
