LT Tire vs ST Tire
I assumed I wanted ST Tires for my camper and some people are telling me to go with LT Tires. Now I'm confused, and guess I shouldn't assume.

Here is a link to a very good explanation of the govt. testing requirements for each tire type. The actual govt. regs are available, but are difficult and time consuming to research as they keep referring to different sections of the law.
This person did all the work and put this together:
Plain English Testing standards for ST and LT Tires
That so-called "study" gives neither sources nor references of any kind for the information it purports to base its conclusions on. Well, except for nods to other posters here in the Forums. It reads more like a church bulletin than a scientific paper: preaching articles of Faith to The Converted.
Best advice given here came early on: Consult a local tire guy you trust, and buy accordingly.
What was this then?
