This was Timmos argument to begin with. He’s stuck on LT tires for smaller trailers 14-15” rims that LT tires are unavailable or all but unavailable. And of the very limited choices, they are rated much lower weight than comparable ST tires.
So bottom line, doesn’t matter what the test methods are, if you can’t buy the tire you want.
Grit, if you read my posts in that thread, I "second the emotion" and shared my LT experiences. You were the one trying to debate LT vs ST tires on 14 and 15" rims.
From SeniorGNC's post--
Conclusion:
The difference in high speed performance testing between a ST and LT tire is significant. Both tires are tested through a speed/time profile.
The ST tire is tested 88% of rated load while the LT tire is tested at 85% of rated load. Thus, the loading is 3% higher based on rated load and this slight advantage goes to the ST tire. However, the LT tire is tested at significantly higher velocities (nearly 100 mph!) when compared to a ST tire. This is a 16% advantage to the LT tire. Thus, again the overall test for the LT is more rigorous than the ST test.
