"How about speed limiters on the TV when the RV is hooked up?"
This is IMHO one of the primary reasons of ST failures. I have witnessed excess speed many times on the 5,15,10, 40frwys coming back in to the L.A. basin on ANY SUNDAY afternoon.

I do not believe all the snowbirders are speeders yet they experience lots of ST failures. They are generally much larger units and heavier along with being high mileage users.

Goodyear on their Marathons will start the clock at the time of sale if you have the receipt. No receipt and they go by the date of manufacture.
Ex, Can you find the warranty on line? I look today and could not find it that I knew for sure it was for ST trailer tires. I wanted to see what they say about "weather checking". Some tire companies mention it and some do not.
Am doing research for a write-up on Mission brand tires. I believe the design of interest is "Radial ST". When I do a search I find a lot of 2nd hand info such as "A friend had a failure" or "I heard about Mission tire failing" or “I read about these China tires failing"/
What i do not find very often is a clear statement from a user who personal had a failure. The few times there is statement from an owner there is no mention of the tire size or the actual loads on the tires or even how many tires they had and age of the tires. I also do not recall ever finding the DOT provided.
With all the repeated stories on this brand I would have thought it would be easy to get the facts but since there is only a single complaint filed with NHTSA and in that complaint there is no DOT info or tire size and the design is an "FT" and the person filing the complaint said the tires were made by General Tire Co. so that single complaint is very suspect and of little help in trying to look at facts.
If you owned Mission brand tires and had good luck or bad please PM me with whatever data you can. I really do not want to try and write an article based on rumor and hear say information.
Thanks for your support.
You can learn more if you visit my tire blog RVTireSafety
In my opinion as a QS9000 and ISO/TS 16949 Quality auditor the word "Quality" does not appear to be in the RV industry dictionary.

The Montana forum would be a good starting point. Chris

You can also try the Heartland Owner's Forum. They had some Mission OE tires.
Decided to check my tires & placard today. 9700lbs GVWC, 5000lbs axle rating, 2540lbs per (Maxxis )tire. GVWC 460lbs lower than tires rated without deducting pin weight. Guessing low at 20% is 1940 leaving 600lbs per tire as "reserve".
OK... so I read through the majority of posts on this thread and there is definitely a lot of good information here!!
The only thing I am a little unclear about is how the load ratings are calculated between ST and LT tires. I am in the process of researching new tires for my 5er and have found that the Goodyear G614 (LR-G, 14 ply, 3750lb capacity, LT tire) would meet my criteria. One of the shops I spoke to also recommended a Kenda Karrier HD Radial (LR-F, 12ply, 3960lb capacity ST tire).
I am confused as to how a LR-F tire can have a higher max laod capacity than a LR-G tire even if they are ST vs. LT. Obviously the Kenda is about 1/2 the cost of the GY. My trailer axles are rated (according to the placard) at 6840lbs but I know they are 7k axles that the manufacturer reduced the rating on to ensure that the standard LR-E tires (rated at 3420lbs) can be used.
And to top it all off, I found I can upgrade to a 17.5" tire (Hercules H-902 245/75R17.5 135/133L 16 ply) including new steel rims for the same cost as the G614. I am leaning towards the 17.5" option because it seems the tires are more readily available than the G614 (at least around here) and of course because the load rating is total overkill for my trailer at 4805lbs per tire. Also, the replacement cost of the 17.5" tire is about $100 less per tire than the G614, so in 5 years when I need to replace tires, my costs will be less.
Does this logic make sense, or am I going way overboard here when I could safely go with the Kenda tire in terms of load capacity and in turn save a whack of dough? Comments?

Make lots of sense.
Buy the Goodyear over the Kenda but the 17.5 option is better long term! I like the Cooper RM160 for a low cost option from a reputable tire company. Just make sure the steel wheels are right as there are two different kinds... stud centric using 1/2" or 9/16" studs and 60* lug nut taper and hub centric using 5/8 studs. The hub centric can use 90* taper lug nuts with clamp ring or flange nuts.

Others have and will suggest you consider the 17.5 option. I think you have considered the details as long as you confirmed all the components such as axles, springs, hubs, wheels etc.
RE LT load limits vs ST Load limits.
Ther is no direct simple factor to convert load/inflation tables from ST loads to LT loads. ST tires have higher rating becsuse they have shallower tread depth (cooler running), A lower speed limit 65 vs 75 or higher for LT and ST type are intended for Trailer use only in Highway Service. I know of no state that allows people to travel in trailers while in motion so would interpret this to mean not intended to transport people.
