Note that Nelson Funston's Trailer Dynamics paper was written in 1987. I would bet that tire technology has changed somewhat in the intervening 32 years. Still, the paper is interesting and informative.

The steel belted radial was well-established in 1987. I've discussed tires,
particularly trailer tires, with Nelson many times since then, including recently
about the specific tires to get for my trailer. He has never mentioned any changes
to tire technology that would affect us, nor have I heard of anything.

Also, there is nothing in his paper that depends directly on tire technology. It's
the lateral stiffness of the tire tread that is important; then and now, radial
tires have significantly more stiffness that a comparable bias ply tire.



Light truck tires are not available in a size that fits Cobra trailers. Found that out this last summer when I had to replace a blown tire.

Yokohama Supervan Y356 LT195/75R14 fit my ASH 26 E trailer. I got them from
Tirerack.com, and they still carry them. Walmart has them, too, but you might have
to order them first if you want to pick them up locally.
