D-load-rated tires

Load Range C - 50 psi
Load Range D - 65 psi
Load Range E - 80 psi

I don't think 65 psi will cause the rims to fail. I would not try 80 psi though.

According to the Trailer Tire Facts and Information page of Discount Tire, the leading cause of tire failure is underinflation.  The page also says that the combined capacity of the tires should exceed the load by 20%. That would be a minimum. I prefer a little more reserve capacity. The load range D tires should provide it.

Over pressure can cause wheel failure. I run LT 235-80 17s on my wrangler and do not use a wdh.

What is the brand of the tire that is currently on the R-Pod? Have you searched for that brand of tire so see if it comes in a load range D also?

I just replaced the tires on my 2016 R-Pod 179 with load range D Carlisle tires from Discount Tire for the same reason you want to replace yours. In particular, there was significant wear on the outer edges of the tires. They were inflated properly, so the trailer was too close to the top end of the load range for the tires. The stiffer side-walls and higher pressure of 65 psi vice 50 psi should help.

David.  I'm with you.  You got a expensive trailer behind you and putting on cheap tires, doesn't make sense to me.  I have always spent extra on all the cars I have ever purchased and replaced to original tires with Michelin tires.  Not cheap, but what is your life worth?  I have always lived by the motto, "You get what you pay for."  No regrets in all my years.  Save Travels.

Originally posted by TheBum Has anyone tried running tires with a D load rating on their 'Pod? After my experience a month ago with two blowouts, I'm looking for any way to run as sturdy of a tire as possible. Discount Tire has Carlisle HD 205/75R14 tires with a D load rating and M speed rating, but they're a little pricey to buy without knowing if they'll work well.

I bought the same tire in the "C" load range this Spring, from Discount tire. So far, so good. My neighbor spoke well of Carlisle. He is a pretty sharp guy and has experience with the brand. Note that I have 4 tires (tandem axle) so I am WELL within the specifications. Even at maximum loading, I am only at about 60% of their rating. I do recommend getting them balanced - for the same reasons we get the tires on our TVs balanced.

Yes, the Carlisle tires were not inexpensive but, I would rather not have to change (flat) tires on the side on the interstate highway.   I didn't mind spending a little more.
