Heartland Cyclone tire blowout problems

Filed Jul 28, 2025 · Tires · AR

We were driving north on [XXX] from Albuquerque to Aztec, NM driving between 65 and 70 mph. There was no debris in the road and the tire on the passenger rear axle blew out. The tread separation tore up the side skirt and trim. I checked the tire pressure on the other 5 tires and all were inflated to the recommended PSI.

3 of 4 Sendel T07 rims had cracks in the rim spokes. Yes it is available for inspection. 1 tire overheated and delaminated at highway speed and after further inspection of remaining rims replaced them before tire damage occurred. Had I not inspected the remaining rims it could have caused a major accident resulting in injury or death. I had TPMS sensors installed but due to not having it blow out there was no warnings. I just happened to see it happen in my mirror and immediately pulled off. I have sent pictures to the manufacturer and they are being reviewed. This is a MAJOR safety concern.

Checked my tires, air pressure and left for a trip and on the trip the tire blew for no reason. Nothing was hit or any reason for tire to break.

Tl* the contact owns a 2017 heartland cyclone 3611. While the vehicle was being used during a family road trip, the tire blew out. The contact went to get the tire changed and found out that all four rims were fractured. The spring inside the rims were fractured and the springs on the suspension were sagging. As a result, the vehicle could not haul as much weight as it was supposed to haul. The vehicle was taken to an independent mechanic and the rims were replaced. New springs were also ordered to be installed by the contact's husband. The manufacturer was made aware of the failure and did not assist. The dealer was not contacted. The failure mileage and VIN were unknown. *bf

Three separate blowouts over two trips of my dynamic tire, towmax str 235/85 16 e 10ply tires. First incident was a solo tire separation leaving only sidewalls on the rear driver side wheel. Second and third tires were on the same trip one day apart. Tire number two was a slow leak detected by my TPMS and changed without incident examination by the tire expert showed separation. The third tire was a blowout with loss of tread and damage to my side skirt, fender, marker lights and hoses. Because of previous experiences from the first trip I carry two spares. The next day at the rv camp I had all four of the tires replaced with g rated, during that process the last of the original tires showed a separation of the tread but luckily had not blown. Dot adbz gpb 4214. Dynamic tire has yet to make good on the repairs or sent labels to ship the tires for their inspection, it has been almost a year, despite me calling multiple times. Don't use these tires for your 5th wheel.

Defective power king towmax str trailer tires. I purchased a 2012 heartland cyclone new in june of 2012(fifth wheel toy hauler). The rv manufacturer installed towmax str tires at the factory. Within 2 years and less than 5,000 miles three of my tires burst sitting in the driveway. These tires were collected and warrantied by power king. Within the next 1,000 miles of towing the other 3 original tires were suffering the same fate as the first three with the exception that the vehicle was in tow this time and it ripped off the side of my camper. Very little compensation was given to fix the camper and replace the defective tires. $500 was the total for everything. The first three were replaced with the same tires and the next three were replaced with a tire of my choice. Now the tires that were originally replaced with an exact replacement is the reason for this complaint. The tires are 2.5 years old with roughly 6,000 miles of towing on them and I have become the victim of yet another round of tire failures. So in five years I have had a total of 9 towmax str's fail from tread separation while either sitting still or in tow. The previous tires that I have had fail were recovered by the manufacturer and were never seen again even with my concerns of a major issues with the tires. I have researched this specific tire and it seems to be a common occurrence for them to fail and the manufacturer to provide little assistance in repairing or replacing damaged equipment . This failure has happened sitting still and in tow multiple times. I believe that a serious recall is needed before other individuals suffer the same damage or possibly worse when campers or trailers are in tow. Pictures can be provided at a later time.

On 8/11/2015 while taking my cyclone 4200 in for service I had a tire blow out. I have only had the rv for 10 months and it has spent most of that time in the shop for warranty work. When I first purchased the rv I tried to get the dealer to change them out as I notice some indentations on the side walls. The dealer stated that it was normal and from the molds however I didn't get a warm fuzzy about this answer. Now with about 2500 miles on the tire at the time of the incident I was traveling west bound on i10 and had just gotten on the interstate when the tire blew out. I was traveling at approximately 45-55 MPH. I immediately slowed and pulled over. It was the front ds tire on the rv that blew and caused damage to the wheel well and side of my rv. The tires were power king towmax st235/80r16 dot 0714. I have an air compressor that I bought and keep in the rv so that I can monitor and properly maintain the tires. The tire pressure is checked everytime I hookup to my rv and it is maintained at 80psi. I contacted dynamic tire which handles these tires and they wanted me to send them all to them. I only sent the one that had blown for analysis. They came back denying paying for damages to my rv saying that the tire had signs of being ran under inflated from rim flange impression on the side and stress marks on the bead. The damage they are stating is from where I had to drive slowly 5 MPH to the next exit in order to get to a safe area to change the tire out rather than trying to keep this 45' monster on the side of the busy interstate and change the tire (unsafe staying there). These tires need to be banned from being allowed on the road in the us!!!! I have photos from when I tried to get the dealer to change the tires, and from the tire that blew out prior to me moving to a safe area, and I have the report that they provided me from their eng, and the other tires.
