Greenball Tow-master tire failures

Hi Everyone,

I'm new to these forums, but not to RVing. We own a 2005 Dutchmen Denali travel trailer.

We came back from a trip Labor day weekend and blew a tire. After some discussions with other RV owners we know, it seems that there have been a bunch of us who blew tires this past year.

What we are finding is that they are all Greenball Tow-master tires.

So far there are 5 tire failure incidents in the past 1.5 months.

My trailer damage was minimal for body work, but the tire caught the wiring harness in the slideout and wrapped it around the axle. We were under it on the side of Rt 66 cutting it from the axle. Not a good place to be.

Anyhow, I just wanted to put the word out in case anyone is researching tires. These will never be on my RV again.

The tires were put on in April of 2013 and have less than 2K miles on them. Most of the others we talked with had the same scenario, fairly new tires with little wear and they blew.

For those who question the circumstances, we were traviling roughly around 60 MPH on RT 66E in VA, clear skies, it was around 90 deg. Tires had been pressure checked before taking the trailer out. We were approx 45 minutes into our trip.

The trailer is well within the load rating for those tires.

Hopefully this post will keep someone else from having the same troubles we've been experiencing.

Happy Travels
Bonnie

Yes you aren't the only one that has had RV tires fail. I had 14 ply USA made Goodyears fail quite a few times on my Teton. Some did little damage others quite a bit. Twice had two fail within ten miles of each other.

If you continue to use any ST tire that is made in China, expect many more blow outs. The consensus here, and on other forums, is that Chinese trailer tires are pure junk. The only ST tires that are worth anything are Maxis M8008, which are NOT made in China. Those of us who have made the switch to LT truck tires have put the blow out bug behind us. I use Michelin XPS Rib, 235/85R16. Make the switch.

Thanks for the recommendations, azdryheat.

We're most likely pulling the tires and replacing them, even though they have little wear. Such a waste, but I'm convinced if we don't, we're just testing our luck.

Maxxis ST tires are made in Thailand. However they are made to a much better standard than anything else on the market. I will have to search for the link, but someone was comparing the weight of them to the Goodyear Marathons and some other tires and they are a couple of pounds heavier and are of much better construction. FWIW GYM tires were being made in China but production of some sizes has been switched back to the USA. Read any RV forum and you will read horror stories of blowouts with just about every brand EXCEPT Maxxis.

What I find interesting is that Maxxis states on their website for trailer tires to not load them over 80% of the load rating.

Most RV manufacturers seem to not allow for that. I know that my 2015 Coleman has a GVW of 3800# allowing for a 15% tongue weight it puts the tires at or very close to the maximum load. Based on the 80% suggestion I shouldn't have more than ~2860# on my tires. Obviously there is a major disconnect somewhere between tire design, testing requirements and reality. I do know that there is a very strong lobby by the tire manufacturers that has kept the DOT regs very weak for ST tires versus passenger car and truck tires.

On a three axle trailer that's true. On a two axle 7k lbs rated each trailer, LT truck tires still failed on mine. Once I went to 17.5 my tire problem went away.

Aaron, you must have had the good Goodyear Marathons on your Airstream. The US built GYMs had a tendency to blow the sidewall, rather than the tread. It was a rare blowout the would destroy the wheel well or damage the skirt.

I think the disconnect is with the RV manufacturers, install bare minimum tires and let the purchaser worry about them, because their answer is take, "It up with the tire manufacturer".

I certainly see the difference between the OEM Load Range E and the Gladiator Load Range G. The OEM PowerKings were right at their load limit, the Gladiators give me a nice comfortable margin for error.

Nope... DelNats and Carlisle. Goodyear got on my **** list a few years back over a bad set of tires on a truck I had.

When the AS hits the road it will be running on Maxxis. One of the things I really like about the 70's vintage AS is the light weight. Mine is a 31' and the GVW is 7200#, my rolling weight was a tad over 6,000# for most trips. I have never managed to load it to the max, even with a full tank of water on board.

Of course they would fail on a 7,000 pound axle. Most of us have 6,000 pound axles and the LT's are perfect.
