Are the tires that come with the TT from the store cheaply made? I am going to puchase one soon for fulltiming since my work takes me all over the midwest. I think im already set on one with 4 whe...

The tire industry looked at the requirements needed for trailer applications a designed the ST to do the job. If the tire industry thought an LT was a good choice for trailers they would be selling them instead.
Actually the tire industry gave us the ST as a compromise between the low cost passenger tires and the higher cost light truck tires.
Guess you weren't around before the ST tire hit the streets and all trailers came with a passenger tire or a light truck tire.
The trailer industry has always used the LT (light truck) tire as OEM by various brands of trailers or a certain lines. Many brands use the LT as a upgrade option.
An ST tire is also designed to withstand braking but its principle design feature is the resistance to the heavy sidewall strain of a TT and other trailer types. LT are not tested for this because it is not expected in their use.
Not according to the FMVSS testing as they both have the same bead unseating tests to pass.
Having made a living pulling various sizes of trailers I found out the hard way the ST was good for approx 10k-15k miles if it lasted that long vs 60k-70k for a LT tire on the same trailer using the same brand axles/wheels/ as our RV trailers.
For those that are stuck with the idea that LT and ST tires are some how different or the ST is some how superior in sidewall stiffness or other ST tire myths should read some of the Tireman9 (Roger Marble) rvtiresafety.com tire blog on the subject or CapriRacer (Barry Smith) comments on this web or his answers on allexperts.com website. Both are tire industry engineers and not just some guy with a tire blog.
