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.

Psi / Load Index |

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.

1999 GMC C3500 Sierra SL recommended front tire pressure for 245/75R16 front tires is 65 psi. 1999 GMC C3500 Sierra SL recommended rear tire pressure for 245/75R16 rear tires is 80 psi.

Check 1999 GMC C3500 Sierra SL tire load inflation chart for 1999 GMC C3500 Sierra SL weight and tire load index.

1999 GMC C3500 Sierra SL tire pressure 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 it 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.

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 the vehicle 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.
- Check 1999 GMC C3500 Sierra SL tire pressure when tires are "cold" and have not been driven for at least three hours. Never adjust tire pressure when tires are "hot".
- 1999 GMC C3500 Sierra SL tire pressure changes 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 vehicle 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 your 1999 GMC C3500 Sierra SL tires. Low 1999 GMC C3500 Sierra SL tire pressure can cause tire underinflation, and high 1999 GMC C3500 Sierra SL tire pressure can cause tire overinflation. Check 1999 GMC C3500 Sierra SL tire pressure regularly to avoid overinflated and underinflated tires.

Tire inflation value listed on the sidewall of your tire is its maximum tire pressure, and not a recommended 1999 GMC C3500 Sierra SL tire pressure. Use correct tire inflation listed on 1999 GMC C3500 Sierra SL tire pressure chart found on a sticker on driver's door jam or in vehicle's manual.

Maintain proper 1999 GMC C3500 Sierra SL winter tire pressure by adding air to your tires as needed to the recommended tire inflation level.

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

**What is recommended 1999 GMC C3500 Sierra SL tire pressure?**

Select 1999 GMC C3500 Sierra SL tire size to find recommended tire pressure for 1999 GMC C3500 Sierra SL tires.

**Where do I find recommended 1999 GMC C3500 Sierra SL tire pressure setting?**

You can find recommended 1999 GMC C3500 Sierra SL tire pressure in vehicle owner’s manual, on sticker placard on driver's door jam, inside glove box compartment or fuel door.

**How to check 1999 GMC C3500 Sierra SL tire pressure?**
