Trailer tires are not constructed the same as car tires. They are rated for more sidewall load to handle the extra stress. Most trailer tires are bias ply, because steel radials retain a lot of heat during trailer use, however there are radial trailer tires too.

I had a blowout coming back from an NMRA race a few years back. The local gas station helped me out by giving me a radial car tire and mounting it, all for free. I was in the middle of nowhere, so it was the all I could do. About 200 miles later, the tire overheated and blew out. This was just a Lightning truck on an open trailer, not some 15k lb load or anything.
