Vehicles with Tire Pressure Monitoring System (2005–)

If you are concerned because the TPM lamp is on, please remember that vehicles with the tire pressure monitoring system (TPMS) may experience a situation where the warning light is on, yet the tire pressures are correct. Be sure to check the pressure on all of the tires.

Please be aware of the following:

  • The tire pressure monitoring system (TPMS) will warn the driver of a low tire pressure based on the manufacturer recommended cold placard pressure (the placard is located on the driver's side B-pillar).
  • The tire pressure will vary with temperature by about 6.9 kPa (1 psi) for every 6.5° C (12° F). When the outside temperature decreases, the tire pressure will also decrease. Dodge recommends adjusting the tire pressure for this decrease in pressure. Please refer to the vehicle owners manual for information on how to properly inflate this vehicle’s tires.
  • The tire pressure will increase as the vehicle is driven. This is normal and there is no need to adjust for this increased pressure.
  • The TPMS will warn the driver if the tire pressure falls below the low pressure warning threshold for any reason, including low temperature.
  • The tire pressure monitoring system will continue to warn the driver of low tire pressure as long as the condition exists, and will not turn off until the tire pressure is at or above recommended cold placard pressure. Once the low tire pressure warning has been illuminated, the tire pressure must be increased to the recommended cold placard pressure in order for the TPMS warning lamp to turn off. Once the updated tire pressures have been received, the system will automatically update and the TPMS warning lamp will extinguish. The vehicle may need to be driven for up to ten minutes above 25 kph (15 mph) to receive this information.
  • In order to properly maintain vehicle tire pressure, please refer to the owners manual for additional information regarding tire inflation. Note: Tire pressure should always be set based on cold inflation tire pressure (defined as the tire pressure after a vehicle has not been driven for three or more hours—and in outside ambient temperature).
  • Seasonal temperature changes will affect tire pressure—the tire pressure monitoring system will monitor the actual tire pressure in the tire.

All Wheel Drive Power Transfer Unit Failure

The all wheel drive (AWD) system used on minivans uses a power transfer unit (PTU) that connects the front drive components to the rear drive components. The PTU may fail if identical tires are not used on all four wheels. A difference in tire circumference as small as 0.5 percent is enough to cause a PTU failure.

PTU failures related to mismatched tires are not covered under warranty. Important points to consider are:

  • Tires should be rotated every 7,500 miles or less to maintain even tread wear
  • Correct tire air pressure must be maintained
  • When tire replacement is necessary, all four tires must be replaced with a matched (same manufacturer, model, and size) set

Aftermarket Wheels and Tires on all Vehicles

Installing aftermarket wheels and tires on cars and trucks in the attempt to individualize one’s vehicle with a custom look is very popular. However, installation of these custom wheels and tires presents a number of problems that challenge the performance, handling, and safety of the vehicles. First off, due to Federal Emission Laws (though virtually unenforceable at this time), it is illegal in many states to replace wheels and tires with a different size than came equipped with the vehicle. Though it's quite common for people to put oversized custom wheels on their vehicles, changing the diameter of the wheel/tire has a direct effect on the vehicle's emissions.

Example
The Chrysler 300s come equipped from factory with 17 or 18” wheels. It is common for vehicle owners to install 20 or 22” custom wheels and tires to enhance the look and appeal of these vehicles. The problems resulting from these enhancements include:

  • Extremely harsh ride due to excessively low profile of tires
  • Sluggish acceleration
  • Poor handling
  • Decreased fuel mileage
  • Accelerated wear on all components
  • Braking issues due to increased mass (weight of wheels)

The suspension, driveline, and brakes are not designed for the mass and weight of these wheel/tire assemblies. Any change in unsprung weight from design specifications directly affects these conditions. The overall wheel/tire diameters change the way the vehicle tracks and affects wheel alignment. Note: SRT-8 vehicles come with 20” wheels, an upgraded XHD Suspension, and larger 18” brakes with brembo calipers. This scenario applies to all vehicles.

Chrysler Tire Questions and Answers

Sounds like wheel bearings but mechanic says not problem with brakes or bearings even after 40,000 miles of noise. Noticed the noise after new tires on front at 80,000 miles. That was 40,000 miles...

I replace the front tires, still the same. At first I thought one tire might have a bubble on it. Not the case. When I make a turn at the corner it makes a ticking noise. When I am just going down ...

LB Cruzn, 2007 Chrysler PT Cruiser, 2.4L 4 Cylinder, Hamilton, OH

Car has 21,000 miles on it. this week replaced front axels as car was vibration badly in the 45-55 MPH range. This replacement took care of that problem BUT now the car vibrates badly in the 15-25...

The car doesn't shake in the steering wheel. Only when my foot is on the gas at 60+ Mph once I let off it stops.
