And the Westlake G-Rated tires so far have good reliability reviews.

I think upgrading from E-rated to most any G-rated tire brand is a good move. The 2 brands that seem to have the best result may be Goodyear g614s and Sailun G rated tires. I went with Goodyear’s before my first long trip. I was looking for Sailuns but they weren’t available locally.

My friend had an E-rated Goodyear Marathon tire destroy itself on his loaded horse trailer. He put G-Rated Carlyle's on it.
