Outfit your travel trailer, pop-up camper, boat trailer or fifth wheel trailer with the Goodyear Marathon Radial. Its an excellent trailer tire, and it's made in North America. The Goodyear Marathon Radial makes it easier to take your "toys" with you, thanks to a rounded profile that enhances ride quality. The tread design is symmetric, which means rubber-to-road contact is constant. And that, in turn, increases stability and traction."I have these tires on a 6x10 enclosed trailer that I use to haul a large Harley touring bike. I have taken a short trip and a long trip with these tires and I'm very satisfied with both the wet and dry performance. All miles have been in Florida and to Texas and back in the summer heat along with the summer downpours. I feel a better track with these tires than I had with the old bias ply tires that they replaced." -- Tire Rack Consumer Review, FL

Thank you for your inquiry. Unfortunately Tire Rack does not carry trailer wheels due to the complexity and large variety of fitments.
Thank you.
We just recently began carrying another brand of trailer tires called PowerKing's. Email me directly if I can help you explore this option. -Marshall@Tirerack.com
In order to assist you with your inquiry, we would need to know the bolt pattern you are looking for, the hub size of the trailer, etc. Please advise. -Marshall@tirerack.com
Either the 235/75R15 that you mentioned or the 225/75R15 that the conversion chart shows would probably be the closest. Neither is perfectly exact, but that would be in the right ballpark. -ben@tirerack.com
