New trailer tires?
 

Just had both tires blow out on my single axle trailer within 20 miles of each other. Looks like the side walls went. They were radials. I had got 3 years out of them before blowing out. Should I stick with radials or go bias? I had some Kumho 857s on the trailer. I got home with my spare and another boat's spare (we were following each other).
