I've had Kumho Radial 857 in 205/R14C load range D for several years now. Speed rating R(106mph), 65psi. Tire wear has been really good and they run cool. Bought thru Belle Tire special order (not cheap at $150). These are for commercial light truck, transporter, van and trailer per the manufacturer. Probably the only LT tire for 14's. I might buy again when needed if still available but will probably spend less with the GY Endurance. I have about 15,000 miles with no issues.
My other choice(which are installed on my single axle cargo trailer) is the GoodYear Endurance ST205/75/R14 load range D, speed rating N (87mph), 65psi. I have about 4000 miles on these and so far so good. A little more reasonable at $115.
