Tire Pressures, Requirements and Recommendations
VIDA, SMB 17-006, owners' manuals
Tire pressure is a critical element of vehicle performance. Correct tire pressure is important for:
achieving good fuel economy
achieving optimum comfort and good driving characteristics
helping to prevent flat-spotted tires due to low tire pressures
As stated in the Model Year 2007 owners' manuals:
Under-inflation is the most common cause of tire failure and may result in severe tire cracking, tread separation, or 'blow-out,' with unexpected loss
of vehicle control and increased risk of injury.
Under-inflated tires reduce the load carrying capacity of your vehicle.
Over-inflation is also undesirable. Over-inflated tires can be stiff and unyielding, and will cause the vehicle to ride more harshly and loudly.
Under-inflation or over-inflation may cause uneven treadwear patterns.
There are many opportunities for the Volvo retailer to check and maintain proper tire pressure, from new vehicle storage, to delivery, through the service
life of the vehicle. This TNN is designed to summarize and highlight Volvo's requirements and recommendations regarding tire pressures.
Tire pressures should always be checked cold. Tires are considered to be cold when they have the same temperature as the surrounding (ambient) air.
This temperature is normally reached after the vehicle has been parked for at least 3 hours.
After driving a distance of approximately 1 mile (1.6 km), tires are considered to be hot.
When the weather temperature changes, tire inflation pressures also change. A 10-degree F (5-degree C) temperature drop causes a corresponding drop
of 1 psi (7 kPa) in inflation pressure.
All new Volvo vehicles are delivered from the port to the retail facility with tires at 'transport pressure', which is 43 psi (300 kPa). As indicated in
Service Manager Bulletin 17-006, Retail Car Delivery Process, Stock Maintenance checks require that tire pressure be checked every 60 days, and be
maintained at 43 psi (300 kPa). This is also true for vehicles on static display, such as the showroom or outside display areas. This transport pressure
must be maintained until just before retail delivery.
Failure to maintain transport pressure in tires may result in tire damage not covered by the tire manufacturer's warranty.
