Are New Wheels Needed if Upgrading From Load Range C to Load Range D Trailer Tires
Question:
I have a 2014 KZ Sportsmen 16BH Single Axle Travel Trailer. UVW is 2,263 lbs and GVWR is 2,800 lbs. After experiencing a tire blowout, I recently replaced the factory installed ST 175/80R13 tires with new Goodyear Marathon ST 175/80R13 Load Range C . Unfortunately I experienced another blowout on the new tires after only a few hundred miles. I am confident the trailer was not overloaded, tire pressure was maintained at 50psi as recommended, and I was traveling at the maximum recommended speed of 65MPH. I am concerned that the limit of Load Range C tires 2 X 1,630 = 2,720 lbs is just under the GVWR of 2,800 lbs. I also suspect one side of the trailer is slightly heavier than the other because the A/C, refrigerator, inverter and storage tanks are all on one side of the trailer - this side that experienced both blowouts. I am considering new tires with a Load Range of D specifically, Item # AM10210 - Karrier ST175/80R13 Radial Trailer Tire. Will I need new wheels/rims if I upgrade to a Load Range D tire?

Helpful Expert Reply:
You can absolutely upgrade to the Karrier ST175/80R13 Radial Trailer Tire - Load Range D # AM10210 tires without needing new wheels and rims. These tires have a maximum capacity of 1,610 lbs at 65 psi so a pair of these will have a 3,220 lb capacity.
It seems likely that you have figured out the reason why you are experiencing blowouts because if one side of your trailer is significantly heavier than the other, that tire is going to build up excessive heat, which is what causes blowouts. If at all possible try and even distribute the weight in the trailer though I realize this might be difficult considering you have so much heavy cargo on one side.
I have added a link to a video review of these tires for you to take a look at as well.
