What's wrong?
The tires on a 2018 Heartland Sundance XLT Tt trailer carry the trailer's weight, absorb road impacts, and keep the trailer stable behind the tow vehicle. The load range printed on each tire tells you how much weight that tire is built to carry. For this trailer, the federal certification label called for Load Range D tires.
On affected trailers, Heartland installed ST205/75R14C tires instead of ST205/75R14D tires. That means the tires on the ground had a lower load rating than the rating shown on the trailer's federal label. A tire with too little load capacity works harder under the same trailer weight, especially when the trailer is loaded for travel.
The warning sign is visible during an inspection, not felt through the steering wheel. Check the tire sidewall and compare its load range with the federal label on the trailer. If the sidewall shows Load Range C where the label calls for Load Range D, the trailer has the wrong tire rating.
Who's affected?
The scope is limited to trailers built from December 1, 2017, through December 8, 2017.

Not every 2018 Heartland Sundance XLT Tt trailer is on the list. Check your VIN to confirm whether your specific trailer is included.
What's the safety risk?
Tires with the wrong load range can be overloaded for the trailer's weight. An overloaded tire can fail and increase crash risk. The load range printed on the tire does not match the federal label, so check the VIN and have the dealer replace the tires with the correct load rating. Repair is free at any franchised Heartland dealer.
What should I do?
- Check your VIN to confirm your 2018 Heartland Sundance XLT Tt is included in this recall.
- Contact a franchised Heartland dealer to schedule the free tire replacement that corrects the Load Range C tire fitment and installs Load Range D tires.
- Bring the recall notice if Heartland mailed one. If not, reference recall number 18V510 when you call.
- Avoid towing the trailer loaded near its tire limits until the correct Load Range D tires are installed.
What happens at the repair
At the dealer, a Heartland technician replaces the incorrectly installed Load Range C tires with tires that have the correct Load Range D rating for the 2018 Sundance XLT Tt trailer. The tire replacement and related labor are free under the recall. The work is focused on correcting the trailer's tire load rating, so the dealer installs the proper replacement tires and confirms the trailer leaves with the correct rating.

What should I do if my 2018 Heartland Sundance XLT Tt is on this recall?
Check your VIN to confirm your specific trailer is included in recall 18V510. If it is, contact a Heartland dealer to schedule the tire replacement. Reference Heartland recall number 99.01.39 when you call. The repair is free.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to repair the defect at no cost, and Heartland will replace the tires with the correct load rating free of charge at a dealer.
