Hi George
I know all the arguments about the commercial van tires but short of Kumho there might be one lessor known brand that will even advertise them for trailer use let alone recommend them…
In fact Continental flat out said they are not a replacement for the ST tire… the response from the forums here is I loaded the question… I can’t ask about replacing the ST tire with them… I was told if I ask the right way (only provide some of the facts and not even mention it is a replacement for a ST) they will answer differently… I say if you give a part of the information you will get a unreliable answer, even if it’s the answer you want…
Here is their answer to my question…
Dear John,
Web Inquiry: xxxxxxxx
Thank you for contacting Customer Relations at Continental Tire the Americas, LLC.
We no longer manufacture ST tires, and ((the Vanco line is not a suitable alternative)).
We would recommend searching for a dedicated ST tire line.

And this information taken directly from the Continental tire website and catalog about the commercial Vanco tire line… it’s not something I am saying or made up…
1 - “The growing demand for short-distance transport of passengers and goods
also leads to increased requirements so that the performance of modern day
((vans)) nears that of passenger car.”
2 - “The concept of the VancoTM Camper is to use long well-proven Vanco
technique, optimize its performance for distinguished ((motorcaravan))
requirements and thus ((cater to the needs of this specific target use)).”
3 - “The Continental Vanco Camper tyres are part of Continental’s Vanco tyre
range that comprises ((tyres exclusively for vans)).”
I have asked, Can anyone post any information from their website or official documentation stating differently???
To date and as far as I know, No one has… What information would you rely on here???
also
The PA inspection law says say… the mfg. that being the trailer mfg. as the one required to correctly placard the vehicle… there are other provisions in the law pertaining to the trailer tires condition and tread also, but I am not about to search them all out right now…
(g) Tires and Rims - The axles of a vehicle
specified under this subchapter shall be
((equipped with the number and type of tires))
and rims which have a load rating equal to
or higher than those offered by the
manufacturer.
I could go on and on if I wanted to search my files on different computers I no longer use…
All I can say about the chassis and the running gear is they are mostly marginal at the very best… not high quality or structural beams with no webbing in the flange area that gives them strength (and weight)… I have seen many RV frames being repaired and it’s scary to think some of these were on the highway… if you want to know how I feel about the RV chassis and running gear I have many post about it that can be easily searched out…
these short springs are not made for the ride, that is why the ST tire has the rounded sidewalls as a part of the suspension… less of a problem the heavier the trailer is… the tradeoff is, there is always a tradeoff, in part is more heat and the lower speed rating… another thing that effects the ride is the added un-sprung weight of a bigger and heavier tire… when making these changes I believe you need to look at all the implications the change makes, not just will the tire have the weight rating…
