[G & S Russell]

I sold Mastercraft tires for over 40 years. They are Cooper Tire manufactured and worked great on numerous trailers we mounted them on. I have used LT tires on my own trailers for many years and have had no issues. I’ve read other treads that go back and forth between ST or LT. I don’t want to get that started again, and am just saying that from my experience running a tire company, I would be aware if there was an inherent problem. Don’t get me wrong, we also sold a lot of G rated (14 ply) ST tires over the last 10 years or so. The industry answered the need for higher rated trailer tires. That’s the long answer to your question. The short answer is that they should be fine. Just inspect them to make sure there aren’t any fine cracks around the sidewall of the tires from sun exposure.
