Great Customer Service.Learn the difference between load range C and D trailer tires in the same size, and how they affect the capacity and psi rating. See expert answers and customer reviews on ST175/80D13 trailer tires from Kenda and Loadstar.The 37x12.50 is a load range D and the 37x13.50 is a load range E. I don't really "need" the extra weight capacity, but the thicker sidewall would be nice for added strength. I really like the larger footprint of the 13.50 also. The 13.50 must be made of unobtanium and has been on b/o since last year. We changed out our 15 / 205 lr C. For 15/225 load range E.
