Estimated calculations and should only be taken as suggestions.

1999 GMC C3500 Sierra SL tire load inflation table provides tire pressure psi values corresponding to tire's weight load in pounds (lbs).

If your vehicle is carrying extra load, increase your tire pressure accordingly. Never overinflate tires above maximum tire pressure indicated on tire sidewall.

If you replace your original equipment tires with plus size tires, or tires with different tire size, make sure to use tire load inflation chart to find corresponding tire pressure for your new tires.

1999 GMC C3500 Sierra SL has original equipment tire size of 245/75R16 for front tires and original equipment tire size of 245/75R16 for rear tires.

Recommended tire pressure for 1999 GMC C3500 Sierra SL front tires is 65 psi, and recommended tire pressure for 1999 GMC C3500 Sierra SL rear tires is 80 psi.

1999 GMC C3500 Sierra SL tire pressure range depends on its tire load carrying capacity, so make sure to check tire load inflation chart for 1999 GMC C3500 Sierra SL tire load indexes, weights and recommended psi.

Tire pressure for 1999 GMC C3500 Sierra SL is affected by changes in atmospheric temperature. Use tire inflation temperature chart below to identify tire pressure fluctuation with changes in temperature in order to adjust tire pressure in 1999 GMC C3500 Sierra SL tires and maintain tire inflation at recommended levels.

Change in Temperature represents the difference between current atmospheric temperature and the one used to set your vehicle's recommended tire pressure. Adjusted Pressure is the actual tire pressure at current temperature change. Pressure Difference shows by how much psi your tires are overinflated or underinflated.

Estimated calculations and should only be taken as suggestions.

1999 GMC C3500 Sierra SL tire load inflation table provides tire pressure psi values corresponding to tire's weight load in pounds (lbs).

If your vehicle is carrying extra load, increase your tire pressure accordingly. Never overinflate tires above maximum tire pressure indicated on tire sidewall.

If you replace your original equipment tires with plus size tires, or tires with different tire size, make sure to use tire load inflation chart to find corresponding tire pressure for your new tires.

Tire Pressure Tips
  • Recommended tire pressure for 1999 GMC C3500 Sierra SL tires can be found in vehicle owner’s manual, on sticker placard on driver's door jam, inside glove box compartment or fuel door.
  • It is important to use tire pressure recommended by GMC manufacturer, not tire pressure listed on tire sidewall.
  • 1999 GMC C3500 Sierra SL tires can naturally lose on average 1 to 2 psi of air pressure monthly, so check tire pressure regularly and add air as needed to maintain proper tire pressure at recommended inflation levels.
  • Check tire pressure in your 1999 GMC C3500 Sierra SL tires when they are "cold" and have not been driven for at least three hours. Never adjust tire pressure when tires are "hot".
  • Tire pressure in 1999 GMC C3500 Sierra SL tires can change by about 2.5% for each 10°F change in atmospheric temperature. Adjust tire pressure accordingly.
  • Underinflated tires can significantly reduce the life of 1999 GMC C3500 Sierra SL tires and reduce fuel efficiency by up to 5%.
  • Overinflating 1999 GMC C3500 Sierra SL tires does not increase their load-carrying capacity. Always use tire inflation value recommended for your 1999 GMC C3500 Sierra SL by manufacturer.
  • When replacing original equipment tires for 1999 GMC C3500 Sierra SL with plus size tires, or tires with different size, check tire load inflation chart to find proper tire pressure for your new tires.

It is important to maintain proper tire pressure for 1999 GMC C3500 Sierra SL tires. Low tire pressure will result in tire underinflation, and high tire pressure will result in tire overinflation, which can compromise tire safety, cause tire blowout, decrease fuel efficiency, cause uneven tire wear and reduce tire tread life. Check 1999 GMC C3500 Sierra SL tire pressure regularly, and monitor 1999 GMC C3500 Sierra SL tire inflation levels to avoid overinflated or underinflated tires.

Keep in mind that tire inflation value listed on tire sidewall is a maximum tire pressure the tire can be inflated to, and not a recommended tire pressure for 1999 GMC C3500 Sierra SL. Use recommended tire pressure listed on the tire pressure chart found on a sticker on driver's door jam or in 1999 GMC C3500 Sierra SL manual. Also, pay attention as your 1999 GMC C3500 Sierra SL may have different recommended tire pressure values for front and rear tires. Keep 1999 GMC C3500 Sierra SL tires inflated within reasonable psi range of the recommended levels.

If you replace 1999 GMC C3500 Sierra SL original equipment tires with optional tire sizes or you switch to plus size tires, make sure to follow guidelines for the application of load and inflation tables to find proper tire pressure for your new tires on your 1999 GMC C3500 Sierra SL. Tires with the same load index, regardless of tire size, may carry the same load, but not always, and they may require substantially different inflation pressures. Tire load index may not be used independently to determine replacement tire acceptability for load capacity. An equal or greater load index does not always correspond to equal or greater load capacity at all inflation pressure settings.

Always refer to the 1999 GMC C3500 Sierra SL owner’s manual for any specific safety advice regarding the application of replacement tires.

1999 GMC C3500 Sierra SL replacement tires must have equal or greater speed rating compared to the original equipment tires if your 1999 GMC C3500 Sierra SL speed capability is to be maintained. It is recommended that tire installers refer to the 1999 GMC C3500 Sierra SL owner’s manual to identify any tire speed rating restriction or recommendation that could affect the operation of the vehicle. If 1999 GMC C3500 Sierra SL replacement tires have a lower speed rating than 1999 GMC C3500 Sierra SL original equipment tires, the vehicle’s speed must be restricted to that of the replacement tires.

Original equipment tires that come on your 1999 GMC C3500 Sierra SL will have the proper tire load index, so stick to that number or higher when you replace them with new tires. Tire load index tells you how much weight your tire can carry. Putting too much weight on your tires will overload them, and can cause tire damage, premature tire wear or even tire blowout. You can check 1999 GMC C3500 Sierra SL manual to find the recommended tire size and load rating.

1999 GMC C3500 Sierra SL tire pressure changes with temperature, so check your 1999 GMC C3500 Sierra SL tire pressure when outside temperatures change. During colder months when temperatures drop, 1999 GMC C3500 Sierra SL tire pressure will decrease also by approximately 1 psi for each 10 degrees Fahrenheit. Maintain proper 1999 GMC C3500 Sierra SL winter tire pressure by adding air to your tires as needed to the recommended tire inflation levels.

1999 GMC C3500 Sierra SL tire pressure should be checked when tires are cold, after the vehicle has not been driven for at least three hours. It is best to check your tire inflation pressure in the morning, after the vehicle has been parked overnight.

If your 1999 GMC C3500 Sierra SL is equipped with tire pressure monitoring system (TPMS), pay attention to tire pressure warning light being on. Ensure your tire pressure sensors are working properly to stay alert and enjoy a safe ride. If your tire pressure warning light is on, check front and rear tires to make sure they are properly inflated.

What is my recommended tire pressure for my 1999 GMC C3500 Sierra SL?
Recommended tire pressure for 1999 GMC C3500 Sierra SL is determined by the 1999 GMC C3500 Sierra SL manufacturer based on your vehicle's characteristics and tire sizes. Select your 1999 GMC C3500 Sierra SL tire size to find recommended tire pressure for 1999 GMC C3500 Sierra SL tires.

How do I find my recommended tire pressure setting for my 1999 GMC C3500 Sierra SL? What should my 1999 GMC C3500 Sierra SL tire pressure be?
