bad tires , best replacement 235/80r16

[selnoil]

Hello All,
I am sure this has been asked 100 times but I am new to this forum and search did not find what I need. I have a 2012 nearly 40' Keystone 5th wheel that is about 10-11k dry. This past weekend we had a blow out on the right rear causing several thousand dollars damage. The tire had a cord failure even at proper pressure and such. The current tires are Power King Towmax STR 235/80R16 load range E's. Looking them up it appears many people have had the same failure.

Anyway long story short what have you found to be the best tires out there with the least failures. I am going to change them all based on what I have read with failures of them.

Hey JIMNLIN,

Looking at the tag on the trail it would appear I have the 6k axles. If I had the $$ I would upgrade to the 7K since I feel Keystone put to light of an axle on this rig. I am sure these aluminum rims are not rated for the 110 PSI so what is my best 80 PSI tire.

Our Sailuns are 3 yrs old. We go camping every month and take 2 (500 mi. +) trips a year. Saliuns are still going strong. Considering putting on the truck later this year. Also consider a TPMS system on the camper as well. Good Luck and Happy Camping !!!

Another vote for Sailun. I put a set on my rig before pulling it cross country and not a problem with tires, even on some crappy roads and pulling between 65-75 mph.

Around the trailer world (rv and non rv) towmax = blowmax.
There are better tires out here for a heavy trailer.
I doubt a 16" LT E at 3042 lb capacity will work on a 40' trailer. However if the trailer has 6k axles a commercial grade all steel ply carcass tire like a Bridgestone R250 is tops.
And the Sailun S637 all steel ply carcass in a ST235/80-16 G at 110 psi 4080 lbs capacity will give you many years of service on trailers with 7k axles.
Other 16" ST G commercial class tires that are popular for service trailers are Gladiator QR35.......and Samson GL285....Hercules H-901. These tires work fine for rv trailers also.

New gen ST E at 80 psi and 3500-3640 lbs capacity like Goodyears new Endurance......Carlisle new HD.....and a Provider...... with L and M speed ratings and much improved reliability service over the older ST class of tires.

And don't forget Goodyears G614 LT235/85-16 G at 110 psi and 3750 lb capacity.

As always, good advice from JIMLIN.

Whichever tire you choose, make sure your rims are rated for
a higher pressure (if the tire req's same).

A great source for info on "serious" trailer tires is the Escapees HDT forum, as those folks are towing *heavy* (why they have HDTs).

Ditto the Escapees MDT forum.

Sailun for me too run for 3.5 years with no problem.

Make sure your wheels are rated for 110 psi, and get the Salun G tires.

Another thing to think about is that GY is the only mfr that will step up and pay for damages done by their G-rated tires, should one fail and cause damage. Yes, they are much higher priced which, in effect, is an "insurance policy" that you pay for to cover these damages. IMO, the Sailun, Gladiator and Hercules are enough cheaper, and are reportedly giving such good service, that the near-double cost of the GY's is no longer competitive in any way.

Have said it all along, the Goodyear G614's are no where near worth what they are asking for them , when Sailun S637 is arguably a better tire at half the cost. The Sailuns have a better track record then Goodyear has EVER had.

Paying double for the same tire is ridiculous. IMO Goodyear went that route because of all the failures. I have insurance I don't need to pay double for a tire to be double covered on insurance.

I have also run the Sailun S637 tires for several years with great results so far.

Sailun S637 Load Range G. I have been running them for over 2 years and they still look new. They were also hit when we were sideswiped a few weeks ago and they are just fine. I would highly recommend them.

That might be a bit of overkill for a 14,000 lb. trailer. 🙂

My fiver came with marathon st tires. Within months they where pregnant (sidewalls balloning) the dealer replaced all 5 tires with new Marathon. Sometime the next year 1 tire sidewall balloned so I sold the rims and went to 16 inch Lt tires. I bought uniroyal larado lt225R16 load rated E. They served me well for 6 years and about 16K miles. Then coming home thru Texas I blew 3 of them in one day, along with the damage to the fiver. Not sidewall damage but stright across the thread. I brought 1 carcus back and took it to the dealer and first thing they said. ST tires belong on trailers and LT tires belong on trucks. I told him that the wheels on the trailer follow the truck and whatever the truck hits, so does the trailer. the trucks tirs have over 60k on them and are the same age as the trailers. Always covered and off the ground if it will not be used for a time. I have the CAT paperwoork to show that the trailer only weighed #7780 and that the 4 tires were capable of #10700. I only went in for information as to why they blew. I had checked all tires before starting the day and again just before the second tire blew and checked the temp with a laser thermo (about 124 degrees) I guess and kind and any brand can ruin your day.

Thanks for all the comments!! I probably should have put on the original post that these were the tires the manufacturer sent it off the line with. And I am also a truck driver so very familiar with some of the info folks describe. With the trailer, particularly camper, tires being much different I am not sure of the better produces out there. Going to a "G" tire makes the most sense. I always thought that Good Year Marathons were good until I found a ton of complaints for failures on them too.
