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.

Sadly....nothing is cheaper than the china made ST tire. And nothing was cheaper whe ST tires were all made in the USA. They are what they are.
Some folks with a RV have had good luck with them...others like myself had terrible luck with them even when they were all made in the USA.

I think im already set on one with 4 wheels i just dont know anything about trailer tires. I could be pulling it up to 2,000 mi in 6 weeks. Id rather spend more money and get a tire that wont give me any problems. Compared to a cheap one that will blow out in a really bad place.

Thats a lot of miles and ST tires won't hold up to that kind of use if your talking 2000 miles every 6 weeks.
If the tires are 14" I would go with a Kumho 857 all position tire or the Goodyear G26 cargo tire. Both very popular with all types of trailer owners.

For 15" tires look at the;
Goodyear LT225/75 and LT215/75 Wrangler HT load C and load D.
Another excellent LT is the Maxxis U-168 that comes in 14"/15" and 16" sizes.
Continental Vanco2 in several 15" sizes.
Yokohama RY215 has been very popular with RV and other types of trailer users.
For 16" tires the door is wide open with LT tires from just about any tire company.

How many miles do yall get out of your tires before you have to change em?

I have various sizes and types of trailers and they all have LT tires or a all position tire and even P tires on smaller trailers.
However my present 11200 lb rv trailer has LT215/85-16 E tires at 2680 lb capacity. Ran the 1st set for 55k miles and seven years and currently have about 45k on the 2nd set.
