Tire question again for Voltage 3600

Hmmm, another post asking a tire question with no input on size or load range or what the trailer pertinent specs are.

Looking at a couple of RV dealer websites shows the OPs 3600 Voltage may have a 18xxx GVWR with three 7k axles and 16" wheels. This means a minimum 3500 lb rated tire.

The Goodyear G614 LT235/85-16 G at 3750 lbs/110 psi capacity seems to be much improved.

The Sailun S637 in a LT235/85-16 G also at 3750 lbs/110 psi is a all steel ply commercial grade tire.

Some folks with 16" ST tires have upgraded to 17.5" trailer wheels and commercial grade LT tires.

Now, how long do you want to run those china made ST may pops is strictly up to you. I don't/will not use a ST tire on any of my heavy RVs or equipment trailers. If it was my decision I would dump them in a hurry before a long trip.

Yes!! Also think about all of the time it will take you to handle a claim with your insurance and tire Co. when it rips about half of the side of your trailer off. Not to mention any safety concerns. If you can afford it then do it!

The Voltage 3600 is a triple axle fifth wheel. Also the OEM tires are Load Range E, which are rated around 3400 +/- lbs each and require 80 psi, not 45 psi.

Back to the OP, the general consensus seems to be if you want peace of mind, replace them. It isn't IF, but WHEN they decide to blow out and you can count on it being the most inconvenient time possible.

To get a realistic answer you will need to weigh your trailer axles and your tow vehicle .
You did not say but , if your tires are rated for 1820 pounds each on the sidewall that gives you 7280 pounds maximum on your axle weight .
To achieve that weight rating you must be inflated to 45 psi , not more , not less .
Because ST tires are considerably less money than an equivalent pound rated LT tire it is probably wise to maintain a 15 % reserve capacity .
7280 # X 85% = 6188 pounds .
If your axles scale more than 6188 # then you would be best served to check the condition and psi very frequently .
The most efficient way to eliminate tire failure is to upgrade to a tire that has a higher load rating posted on the sidewall , at tire replacement time .
Simultaneously if you can upgrade to an LT graded tire that adds another 10 % of real world reserve .
I made the switch from 1820 # rated ST tires to 2271 # rated LT tires .
But we do more boondock style camping than RV Park outings.

Rough stretch of I81 in Pa, yeah like the whole state!!!

I cam only relate my experience. Last year I was in the same boat. Going into 2nd year with no name OEM ST tires. Heading out on a 1000 mile trip to Canada made it up and almost back when I had a blowout on a rough stretch of I -81 in PA.
I really do think the rough roads contributed to the problem, nevertheless I had a blowout with some minor body damage. The cheap tires failed due to the rough roads, but the reality is rough stretches of interstate are a part of life and will always be with us.

In hindsight I was lucky. I should have upgraded tires before I left as I was skeptical of the OEM ST tires from day one. While the blowout and changing the tire is a major hassle,the real risk is suffering body damage to the wheel well area from the blowout.
If you are considering the tire upgrade do it now, why risk the body damage?
My new rule of thumb is to ditch the OEM tires after the first season or demand LT tires in the deal at purchase time

Id just leave them as they are
