I need to replace my tires on a Tr-196 trailer (single axle). The Kumho tires have a load rating of 2271 pounds vs. Marathons that are rated at 1870 pounds. Any opinions on the Kumho's or stay with the Marathons? I've got a lot of weight sitting on two tires. The Kuhmos are 205's and the Marathons are 215's.
