The Goodyear Endurance trailer tires don't come in the 8" size according to Goodyear's website. I'm finding that most of those little 8" rim diameter tires come mounted on the wheel. They have worked well for me for 20+ years as long as you make sure to change our your trailer tires every 5-8 years or so.I'd highly recommend not going with the tire that comes installed on the rim. They are referred to as "China bombs" and tend to blow up very quickly. Good Year Endurance trailer tires are what I run and are widely used in the RV industry as well for good / quality trailer tires.
