For anyone else reading this thread, consider Sailun and steel valve stems plus a TPMS system and reduce the chances of being on the side of the road.

Take a look at SAILUN 14 PLY TIRES ,they are great and much more easy on the wallet.

I can and will only attest to my experience. I had my Castle Rocks swapped out for Good Year Endurance after my first trip. There was simply to much even with sway bars and WDH. When the C.R.'s were taking off I put all my weight on the Castle Rocks and they collapsed. Doing the same with the Endurance there was little affect. The Endurance barely budged under all my weight. The sidewalls are very stiff.

Our next trip I could tell a huge difference in the way the trailer pulled and reacted to the crosswinds on the plains of Kansas heading and back from New Mexico.

Again this is my experience and YMMV

Load capacity is the primary reason. For a given x,000# load capacity ST type tires are usually less expensive than LT type tires.


One thing that is true is that RV ownership and especially RV Trailer ownership requires that owners learn more about the selection and proper maintenance of tires used on RVs.

Yes, class action is IMO not a good plan. What might help would be if everyone that suffers a tire failure file a complaint with NHTSA. The information that is required is the full DOT serial. it would also be desirable to provide pictures of the failed tire. If possible the tire itself should be retained if at all possible. The tire should be presented to a dealer of the tire brand for inspection. The reply and report from the tire dealer and tire company should be forwarded to NHTSA as supporting evidence.

No but proper inspection can usually identify suspect tires. I cover proper inspection in detail in my RV tire blog.

Tires are closely matched to axle rated capacity.

Ignoring this leads to what I call the "human factor" that is all too often present before a tire failure. Along with overloading, over speed, etc, etc.

FWIW, I've never seen an ST 205/75R-14-C tire on a 32' trailer. Aren't most TT's in that length equipped with at least 15" tires?

50# is only about 10% of the reserve load your tires should have.

Bottom line is the tire load capacity should be no lower than 110% of the scale load with 120% being more reasonable.

Nobody has a problem with China bombs. Until you do. Then it rips the side of your camper, dump valves, wiring, a hydraulic hose and costs you $1,000’s of dollars.

We run sailun’s on all of our trailers. 235/85/16 g rated tires. We put 75,000 miles on them on our equipment trailers. They are going on the camper.

Make sure you don’t exceed the max air pressures of the rims.

Fascinating. Some folks have blow outs after blow out while others have no problems. Makes you wonder. I think it's like an iceberg. A lot more below the surface.

Anyway, headed for new tires tomorrow..... I would like some insight on tires .... 2018 Hemisphere 282RK GLX - right at 8000# loaded - thinking of the Goodyear Endurance i have read so much about ...
What load range???

Thanks

I have the 2016 version of the same camper. After my blowout caused $1700 in damage to my camper, I went with 5 new Goodyear Endurance tires. Have driven about 10k miles since then with no issues

No Carlisle’s for Me

For those of you unsure of the “China Bomb” controversy being real - read this NY Times article all the way to the end where tire brands are named.
https://www.nytimes.com/2007/06/26/business/worldbusiness/26tire.html
Not the newest info but indicative that safety and quality may not be a priority in some business models...

What’s below the surface is, some Chinese tires have gum strips between layers, and some don’t. Unfortunately, you don’t know which ones you have, until you know. Mine was at 73 psi when it blew. And it blew.

Question to all that are upgrading .... are you changing valve stems to metal and are you having tires balanced ... what do you recommend... Thanks

"Yes" to both of your questions. We upgraded the tires on our Columbus 320 to Advance (manufactured by Sailun), load range G, with steel sidewalls. IMHO, the stiffer ride of the steel sidewalls also makes the trailer handle better, as well as providing better protection against blowout.

The original rims on our trailer will handle the increased pressure. We run 90 PSI (cold) that usually increases to somewhere around 104-105# on the road.

Sailuns are considerably less expensive than Goodyear Endurance, and have gotten very positive reviews from RV'ers on these forums.

To the OP: Put on Sailuns, then take the extra money that you saved by not buying the Goodyear Endurance tires, and invest it in a good tire pressure monitoring system.

The company Jayco being among some folks...They switched all their trailers over to Goodyear Endurance and I was told in person that they were having problems with the China bombs.
