Tire Pressure for the iPhone easily allows you to add all your vehicles tire pressure information in one cool app. You can add unlimited cars, trucks, motorcycles, bicycles and even boat trailers tire information into Tire Pressure.No more looking for the owners manual again and again for the tire pressure information. Just enter it once and when you want to add air to your tires, simply whip out your iPhone and look at your stored tire pressure readings! Tire Pressure for the iPhone supports PSI and KPA inflation measurements so you can use it on any car, truck,motorcycle, bicycle and boat trailers!
Tire pressure allows you to add every vehicle you own. You can add as many vehicles you want. You can also choose one of our custom icons to represent each vehicle as well to make it quicker to find your vehicle when retrieving your tire information. Tire Pressure features animated buttons as well as sound effects when saving your vehicle’s tire pressure information.
Tire Pressure for the iPhone will keep you and your passengers safer as well as save you gas by help keeping your tires properly inflated.
Where do you get your tire pressure information to input to Tire Pressure?
For all vehicles produced since 1968, the original tires sizes and inflation pressures (including the spare) are listed on a vehicle placard. This placard can be located on:
The driver-side door or door jamb (Ford vehicles on the rear passenger door jamb)
Glove box or counsel door
Fuel filler door
The engine compartment
Additionally, some manufacturers also list the original tire pressure in the vehicle's owner's manual. If a car's inflation pressure has varied from that which was recommended by the manufacturer, it's likely that the tire's wear and performance characteristics have also changed.
Some more detailed information on how your tire pressure effects your vehicles:
Under-inflation If your vehicle's tires are under inflated by only 6 psi it could lead to tire failure. Additionally, the tire's tread life could be reduced by as much as 25%. Lower inflation pressure will allow the tire to deflect (bend) more as it rolls. This will build up internal heat, increase rolling resistance and cause a reduction in fuel economy of up to 5%. You would find a significant loss of steering precision and cornering stability. While 6 psi doesn't seem excessively low, remember, it usually represents about 20% of the tire's recommended pressure. Over-inflation If your tires are over inflated by 6 psi, they could be damaged more easily when running over pot holes or debris in the road. Higher inflated tires cannot isolate road irregularities well causing them to ride harsher. However, higher inflation pressures usually provide an improvement in steering response and cornering stability up to a point. This is why participants who use street tires in autocrosses, track events and road races, run higher than normal inflation pressures.
