Trailer King Junk

[ChuckS]

Saw this on another group. Date stamp on these is Apr 2016 as reported by original author. There are great Chinese tires out there for RV use but these ain’t it....

[ken56]

Yep, that's what they do. I managed to put 3k miles on my set that came on our new rig. On a gas stop I noticed one with bulges in the sidewall. I got home without losing it and then replaced them with the Goodyear Endurance. Good riddance.

I had already read about the "China Syndrome" :D , and when we bought the Toy Hauler in October 2016 it was getting too late in the year to use, so we brought it home and parked it. I knew that once we got to springtime, I would hook the trailer up and take it to get new tires put on it. So....375 miles home from the dealership and about 20 miles to the tire dealer in the spring....for a grand total of approx. 400 miles. I replaced them with a set of four Maxxis M8008 tires and couldn't be happier.

IMO, going from a tire that provides 3520# to one that provides 3420# with a 65 MPH speed limit is not a very good trade-off.

Speed is a durability factor. The closer you travel to the tire's speed rating the more stress you put on its ability to carry its load.

I felt good to get by for our first season with the TK's. Replaced for the second season with Carlisle HD's and upgraded the load range to E. HD's have proven to be a good tire over the past two seasons with no signs of degradation.
To those who have not, I would highly recommend adding a TPMS as soon as the checkbook allows.

[ChuckS]

I’d have to say that currently for those towing large fifth wheels or toy haulers.... 11 to 12K and up the Sailun S637 235/85x16 14 ply G rated tire is the best value and best durability on the market.

You've told me that like three times already over the last 14-15 months since I've bought the Maxxis tires. And I'll tell you again.....this is my third set of Maxxis tires on my third different trailer and I've had ZERO issues on any of them. The other two trailers were smaller, but of course so were the tires. And with the others, I routinely ran 70 mph, whereas with this trailer, because of it's size, I normally run 65-67 mph. Thank you though!

totally agree! our trailer came with 235/80x16 TK's so I was happy to learn that the S637's also come in that size. GVWR for our Carbon is 16755, CAT scales show right around 14k fully loaded. I run the Sailuns at 90 psi and absolutely love 'em!

Started reading this Forum in 2012 and the China tires were and still are a hot topic. I posted on 5/27/2017 on replacing my 6 year old Power Kings with Goodyear Endurance and upped the rating from D to E. Was always uptight with fear one of my tires would blow. Why my Power Kings gave no trouble is because they had a good safety margin compared to the tow weight of our trailer,

Speed was kept to 55 more or less and the PSI and heat I monitored with Tire Minder set up. When you look at new trailer models the tires used on them will be the same rating on several models as the weight goes up and the safety margin goes down. Tire dealers have told me the sell used China tires from trailers for use on light utility duty trailers and they have no problem. If the trailer you buy has a maximum weight that is anywhere close to the max weight listed on the tire, follow what others are saying on this sight and replace them. Quality tires will work at their max weight, cheap tires will blow!

The sailun tires seem to be a "hot" item for heavier trailers. Those steel cased tires have bead to rim requirements a little different, sometimes, from like sized polyester tires. Therefore most manufacturers post this note on their web pages; * All steel construction specifically designed for Trailer application only. Requires special high load capacity wheel. Consult wheel manufacturer for proper application.

That warning is in regular & smallish letters in this reference; http://www.sailuntires.ca/PLT/S637st.html

Sorry xrated, I write all my posts from scratch and respond to situations most people overlook, like the ST235/80R16E being manufactured in three different load capacities, 3420#, 3500# & 3520#. All defalt to the lowest value when not specifically identified by the original factory installer. In the past, Keystone has had a problem identify and notifying DOT about that tire's fitments. Its caused them,on many occasions to recall tire placards for inaccurate tire load capacities. You can find some of those placard recalls in NHTSAs data base.

Response from Sailun Tires regarding mounting their S637 tire on standard 16x6 110 psi Sendel TS09 aluminum RV wheel.

Note that Sendel rates this particular wheel at 3750 load capacity while the Sailun S637 tide is rated at a higher load capacity.

I’d not have any issues mounting this tire on my Sendel wheels. I am also currently running Chinese made Geo Star 235/85x16 tire 14 ply tire but when time comes would really consider the Sailun...

Yes the tire is rated at more capacity then the wheel but so what. Stay within the load capacity of the wheel and you’ve got some headway factor with the tires. I can’t see how this could be anything but good considering heat build up, sidewalk flex, etc...

Directly from Sailun......

Chuck, thank you for your inquiry to Sailun tires. In regard to your question about the wheel width. The recommended wheel width is 6.5", however; both 6" and 7" are allowed.

The other point to note is that this tire will carry 4400 lbs. at 110 psi. This will exceed the maximum load of your wheel. The maximum air pressure you will be able to use is 110 psi to carry 3750 lbs. If this is an OE wheel, there should be no issue since it would be spec'd for your trailer and the maximum load for tires, wheels and axles. I have attached the load and inflation chart for your reference.

What kind of TPMS is the most easy to use and trouble free in your opinion?

All good info. Below is a link to the tire's specs just in case you haven't seen it.

The first thing I did was to go to the tire place and have my Trailer Kings replaced , I put LTs on mine and am real happy. We have been pulling for about 45 years and have always put LTs on our trailers and have not had any trouble with them , we do replace them every 5 years though regardless of what shape we think they might be in. I use Cooper Tires.

TST 507, had it on all 10 wheels for over 5 years trouble free. They have user replaceable batteries found at Batteries Plus. Highly recommend.

In RV forum threads such as this one, we get mostly unhappy reviews. The industry, as a whole, compiles all reviews and then remarks. Here is a surprising - for you - list of some of their findings.

Regarding the review on the Trailer Kings - yes - very surprising.

Right off in reading about the Goodyear G614, I noted that this article and it's writers don't have a clue what they are talking about. This is copied from that evaluation: Also, you can access its different sizes when you are planning to purchase it, making it possible to find the perfect fit for your rig.

The Goodyear G614 only comes in one size, LT235/85R16.

Also, this site is suspect, as they have this disclaimer at the bottom of their home page:

Spot on. Notice that it's THEIR recommendations, based on what? No info on a survey, statistics or facts. Any .com (stands for commercial) opinion has to be reviewed and evaluated with who their sponsors are or who paid for the article. I may have been born at night but it wasn't last night. JMHO

So, What's in an independent tire review? Are they any better or worse than unhappy user reportings?

Here's another to ponder.

The first steel cased trailer tire was designed by GY and put into service as LT235/85R16 LRG. It is a true trailer tire and says so right on it's sidewall and is touted by GY as a true trailer tire. The RST on it's sidewall is short for Regional Service Trailer.

The above review included tires for motorized RVs. Michelin does not build trailer tires in sizes below 17.5". In their truck tire data book they describe the XPS as an all position tire, further on in that description they define all position service as drive and steer only.

How many times have you read a post about a tire "blow out" when the poster says everything was checked and in good order when they hit the road? Did the mention their weight having been confirmed from some scales?

IMO a post like that is suspect, without a verifiable weight slip.

This is an invaluable observation. Keystone, and other trailer manufacturers, provide trailers with tires on the edge of their abilities to support the trailer. After loading, traveling on rough roads etc.....they are absolutely beyond their limitations in many, many cases. Know your weights/load, know your tire limitations. I suspect many unknowingly are running either overloaded or right at it. And, I've always said, forget about tires that carry gvw less the tongue weight; get tires that can carry the whole load plus.
