Maintaining correct tire pressure on a semi truck is essential for optimal performance, fuel economy, and safety for the driver. Ensuring that your tires are properly inflated before you hit the road is easy and only requires a few simple steps.
The first step is to locate the air valves on each wheel of the semi truck. Air valves are generally located on the inside of each wheel, near its center. It’s important to be sure that you’re placing the air nozzle on the right valve and not a drain valve, which looks similar but won’t inflate your tires correctly.
Once you’ve identified the correct valves, attach an air hose to the nozzle attached to your compressor and connect it to one of the valves.
Be sure to check your owner’s manual for specific instructions about how much pressure should be in each tire as this can vary greatly from vehicle type to vehicle type. Generally speaking though, it’s recommended that you set maximum pressure at 80 psi (pounds per square inch).
Once all of your tires have reached their optimal inflation levels, check them again with a portable tire gauge for accuracy and adjust accordingly if necessary. You should also verify that your spare tire is properly inflated before setting out on long trips.
Conclusion:
In conclusion, airing up a semi truck is relatively straightforward – simply find the air valves located inside each wheel, attach an air hose from your compressor to one of them, and fill with air until they reach their optimal inflation level as specified in your owner’s manual. Always double check with a tire gauge for accuracy before taking off.
