What tire size

[Tim D.]

Back when I had 14 inch rims and wanted load range D tires, I seem to remember the Kumho being the only brand I could find in a 14 inch load range D radial trailer tire. Those I could find only on line at Tire Rack, and they were out of stock. I switched to 15 inch rims so I could have a load range D radial for which replacements could be easily found while traveling. I started with 205/75R15, which became hard to find. Then I switched to 225/75R15 ( Goodyear Marathon), which fit in the wheel well of my axle-flipped Bigfoot 17. That heavy beast pulled so much better after the switch. The trailer sways less and the passing big trucks do not push me around nearly so much anymore. In my travels I have seen a few Casitas with the 225/75R15 load range D Marathons, so they will fit, perhaps with some lift..

So great to see these kids making memories of camping.

That's what camping is all about.

I now have 225/75 R15s on my 86 Casita LD and they went on with no issue. JMHO.

The Kumho Radial 857 is a commercial tire (not ST, but suitable for trailers), and there are other 14" choices of this type (in various load ranges). Finding the right size in a model of tire for which you will later be likely to find a replacement is a challenge.

Examples include the Continental Vanco line, Michelin Agilis, Maxxis UE-168(N), and Hankook RA08... and of course the Kumho Radial 857. There are 15" options in these lines, as well. These have been discussed quite a bit in this forum before: I suggest using the Google search function within this forum to find references to those tire model names to find the discussions.
