Our teardrop came with ST tires but after hearing of blowouts with catastrophic damage with the "China bombs" from a couple of other teardropers, and these are lite enough that there is no way the tires can be over loaded.
I started looking for non Chinese made trailer tires and could not find any. I ended up with Micheline Harmony passenger car tires and each tire is rated for 1650 lbs, the weight of the trailer fully loaded. I have at times been known to tow at 75 MPH but normally keep it at 65 to 70 and we get 18 MPG
