If you have 16 inch wheels there are many choices .
One is the Bridgestone Duravis R 500 available in 16 but not 15 ..
In a 15 inch wheel there are at least 2 different LT graded tires in a 225/70 R15 size that can be fitted to your current wheels .
They are :
Goodyear Cargo G26 rated 2470 # , made in germany and france.
Continental Vanco 2 rated 2470#, made in germany and slovokia .
Neither are made in china.
Both are graded on an LT scale .
Both will fit where a ST 225/75R15 trailer tire goes on your stock RV 15" wheels .
Recent discussions on this forum have shown that LT tires are graded using a tougher standard .
Increasing the Weight rating in pounds as posted on the sidewall is more important than brand .
I ordered continentals from tire rack on a monday and they were delivered by wednesday recently .

The best way to improve your chances of not having a tire failure is to increase the load weight rating in pounds as shown on the sidewall .
That is measurable .
To rely on brand for improvement is similar to going to a casino .
That is not measurable .
