Recommended Higher Load Capacity for Kenda K550 Trailer Tires

Question

Question:

Here is the info from the sidewall of my present tires. 8 P.R. Max load 1155kg (2540) lbs load range D ST 225/75 D 15 (H78-15) If there isn’t a 15” tire with a greater load capacity do you have 16” rims that will fit my present bolt pattern and then 16” tires with a greater load capacity? My present tires and rims were purchased from you guys several years ago.

I looked up the Kenda K550 Trailer Tires and they are offered in many sizes from 13"-15" wheels. If you can let me know which exact size you have (listed on sidewall of tire), I would be glad to offer a replacement option for you in a higher load range. The Karrier ST175/80R13 Radial Trailer Tire part # AM10210 for example is a 175/8013 tire with load range d rating suited for use up to 1,650 lb rating.

I have attached a full list of our replacement tires below.

The Karrier ST225/75R15 Radial Trailer Tire part # AM10303 is what I recommend switching two. This tire has a higher load rating of 2,830 lbs (D vs. E) than your existing and it will work with your current wheels. The best part of all is that it's a radial ply tire which is better than the bias ply tires you have now as they run cooler and are less prone to blowouts.
