Even seasoned drivers can find themselves overwhelmed with the amount of tire choices out there, so below is some helpful information that can help you know what to look for when considering semi-trailer tires:
1. Load Weight and Usage Affects Lifespan
Even the best tires wear out with regular use, meaning trucks that are on the road with heavy loads frequently are going to need routine inspections performed often and tires are going to need to be replaced to keep up the pace. The MPG you get out of your tires is going to be based partially on the resistance rating, and a lower resistance rating will likely lead to a longer service life. Tires with a higher rating will likely lead to lessened efficiency, so make sure to match the tires you purchase to the amount of work your truck will be putting in each year.
2. Know Your Tread Depth
The depth of a tire’s thread can also impact its efficiency. Although the Department of Transportation requires thread depth on semi trailer tires to be at least 2/32” for trailer tires, many professionals recommended a thread depth closer to 6/32” to 7/32” for the best MPG performance and replacement cost savings.
3. Should you Reposition Tires?
In some cases, you might be able to reposition drive tires to trailer tire positions to get extra life out of them. This approach is that same taken when rotating tires on commuter vehicles. As with commuter vehicles, the same general rules apply in terms of ensuring there’s enough thread depth available to continue service life. While trailer tires may not see as much direct wear as drive tires, a tire that has been repositioned may have less life left than you realize if you aren’t monitoring for thread depths of at least 11/32”.
4. Talk to an Expert
Finally, it always pays to consult with an expert if in doubt. Remember that the safety of the driver and others on the road comes first, and worn or improperly selected tires can lead to everything from easy punctures to serious accidents. Even if you know what you’re looking for in a semi trailer tire, get a second opinion and inspection from a trucking pro for additional peace of mind.
