Goodyear Wrangler tires offer a range of tread pressures ranging from 140 PSI up to 240 PSI.
The pressure range is based on the tire’s compression and rebound characteristics.
Goodyear offers a tire pressure indicator that shows the pressure as a bar graph on the sidewall of the tire.
To determine tire pressure, simply measure the pressure on a rubber tire and add up the values for all the rubber compounds, tires, and pressures in the tire sidewall.
The tire pressure measurement can be made from the tire tread or from the sidewal tread.
To calculate tire pressures on a treadless tire, use a tread gauge to measure the resistance of the tread to load and a tire weight gauge to weigh the tire for comparison.
To test tire pressure for an old tire, measure the tire pressure on the tread on the same tire for 20 minutes.
Then remove the tire from the tread, fill the tire gauge with water and repeat the measurement.
If the tire is still under pressure, the tire must be replaced.
For a new tire, the pressure should be measured again.
The Goodyear tire pressure can be found in the tread gauge or the tire weight.
To use the tire, remove the wheel from the car and replace it with a new one.
After replacing the wheel, drive the car for 10 to 15 minutes until the tire has a pressure reading of 40 PSI or less.
Check tires for wear and make sure that the tire doesn’t have any corrosion or cracks.
For tires older than 10 years, use the new tire with a tread pressure of 60 PSI for a total pressure of 160 PSI on the tires.
Goodyears tread gauges are available in both black and white and are available from Goodyear Tire in the United States.
