CARB Compliance Issues- A Deeper Look at Low Rolling Resistance Tires

If you drive a box type trailer in California (including dry van and refrigerated van trailers) you likely are aware of the low rolling resistance tire regulations that are currently being phased in. What you might not know however is how these tires work and how using them impacts you. Keep reading for all the details, including tips for maximizing your tire investment.

What Are Low Rolling Resistance Tires?

Low rolling resistance (LRR) tires are a special type of tire designed to improve fuel efficiency by reducing the rolling resistance. They are required for certain trailers and tractors as part of California’s Heavy Duty Vehicle Greenhouse Gas Emission Reduction Regulation. As tires move on the road, this resistance turns energy exerted by a vehicle into heat, not forward movement, and can result in a great deal of energy waste. For heavy trucks it is estimated that up to 15-30% of fuel consumption is used to overcoming rolling resistance. LRR tires cut down on this resistance saving money in fuel costs and cutting down on greenhouse gasses.

While required for some tractors and trailers in California, LRR tires can be used anywhere in the country to cut down on fuel expenses.

How Much of an Impact Do LRR Tires Make?

LRR tires can make a big impact on your fuel efficiency. Some studies indicate that making the change to LRR tires could save (each year):

  • 500 Gallons in Fuel
  • 08 metric tons of CO2
  • $1,900 in Fuel Costs
  • 3% Reduction in Fuel Costs

LRR tires may wear out more quickly than standard tires. The full impact you’ll experience will vary depending on the type of tire you choose, whether you have single wide or double tires, and even how your tires are inflated. LRR tires may be more expensive (between $0 and $50 per tire), but most estimates suggest that the increase in fuel efficiency will offset the increase in tire price.

Other Methods for Improving Your Fuel Efficiency

Do you want to get the most bang for your fuel investment? LRR tires can cut down on your fuel bill, but there are other steps you can take to maximize your tire investment and to increase your fuel efficiency when using LRR tires. Here are a few tips:

  • Inflate Properly- Making sure your tires are properly inflated can make a big difference in your fuel efficiency. For example if your recommended inflation is 35 psi, but your actual inflation is only 28 psi, your rolling resistance will be increased by 12.5%.
  • Use LRR Tires for All Tires- Although incremental fuel efficiency increases can be obtained by using LRR tires on just the tractor or trailer, you’ll see the best results when you use LRR tires for all tire positions.
  • Choose SmartWay Approved Tires- SmartWay approved tires are verified by the EPA to meet specific fuel efficiency requirements. See a list of approved LRR tires here.

Navigating CA CARB Regulations- 6 Essential Resources

If you drive a tractor-trailer in California, you’ve likely heard about the new regulations from the California Air Resources Board (CARB). The new environmental regulations have been slowly taking effect over the last several years and are now starting to impact small fleets and solo drivers. If you aren’t yet impacted by CARB regulations, you soon will be.

These regulations are complex and varied. The Gross Vehicle Weight Rating (GVWR) of your vehicle, the size of your fleet, the type of trailer you haul, and even where you drive (like ports and intermodel rail yards) impact which regulations apply to you and when they start applying.

To help you wade through the confusion, we’ve prepared a list of helpful resources to help you better understand the CA CARB rules. Keep checking back on our blog as well. We’ve got posts in the works to help you understand the changes so you can… Travel with Care.

·         Which Regulations Apply to You?– Are you confused about which regulations apply to you? This helpful questionnaire from the CA Air Resources Board will prepare an easy list of regulations based on your answers to 3 simple questions. If you have 5 minutes, you can quickly check out which regulations apply to you.

·         Take a Class– If you learn better in person, take a class. There are several classroom training courses available. Many of the courses (all of the ARB Compliance Training Courses) are free to take. Some are offered as webinars; if you have a computer and internet, you can attend wherever your next load takes you and you can even find archived webinar recordings for some of the courses. Checkout the complete list of available courses (click on the course title to see dates, times, and other registration information).

·         Watch a Video– While you’re waiting for that next load (provided you’re in a safe location of course), take a few minutes out to watch a short video on the CARB regulations. You’ll find a variety of informative videos on the ARB TruckStop official YouTube page.

·         Read a Summary– One of the best summaries of the regulations can be found here. It doesn’t cover everything, but it’s a great place to start.

·         Learn the Penalties– Do these new rules really matter? Check out the list of penalties if you don’t comply.

·         Get Help– Sometimes you just can’t find all the answers you need online. If you need personalized assistance, complete the Diesel Assistance Form and you can receive a reply by phone or email. You can also call in yourself at 1-866-6Diesel. Calls are answered between 8 and 5 Pacific Time Monday-Friday and a 24 hour voicemail system is available.

The CA CARB rules are confusing, but if you drive in California, you do need to learn them. Take a few minutes today and start looking at these resources so you can be in compliance.
