Thought I would ask Jayco for suggestions on possible upgrades for my situation.
Here's my question to Jayco:
"The tires/wheels that came on my trailer have a load capacity less than the gross weight of the trailer. I understand the difference is assumed to be included in the tongue weight.
I am using a weight distributing hitch due to the relatively soft springing of my tow vehicle, a 2009 Hyundai Santa Fe.
Because of the WDH and Arizona's summer temperatures I would like to increase the tire's capacities for an extra safety margin.
What does Jayco suggest in this case? Choices I see include increasing to an ST185/R13 load range C, a load range D tire or upgrade to a 14 wheel. Suggestions?"
And their response:
"Thank you for taking the time to contact us here at Jayco. Because Jayco has not done any type of testing in regards to any tire size other then the ST175/80R 13 C we cannot make any type of recommendation in regards to the modification of the tires. I can only suggest you speak to your local tire professional, Lippert Components, the frame manufacturer or Dexter Axle the axle manufacturer.
I am sorry I do not have an answer for your question today. If we can be of service to you in other ways in the future, please feel free to contact us again at your convenience."
