Load Range C Tires and GVWR on a 19ERD

[VistaCruiser19]

The tire sticker on my 2015 19ERD Vista Cruiser says to use Load Range C tires. It also says my GVWR is 4,120 lb. My load range C tires state they have a max. load of 1,870 lb. each. The GAWR is 3,740 lb.
I have had one blowout already. (Luckily I was doing under 30 at the time.)
It seems Gulfstream rated the tires to match GAWR. I always thought it should be matched to a minimum of GVWR. Anyone know how this is supposed to work?

Your tires are probably ST ( special trailer) tires 215/75R14 , found them in goodyear pressure/ loadcapacity list as only size in C-load with that maxload.

First nowadays 10% reserve is recomended by ( dont know exact american organisation) for tires to GAWR .
This covers unequall weight R/L , always is for TT.
And inacurate pressure reading, wich then 9 out of 10 to high given by gauge, so real pressure lower.
And possible overloaded axle at these ligtweight TT.
Combination of these factors can give more deflection then calculated for, so overheated tire-material, wich punisches by blowing tire or treath separation, mayby only after 2 years, when beginning internal cracks have builded up enaugh.

This smaller size is probably not calculated in maxload for 65 mph, as all 16 inch ST are, but also as LT for 99mph ( 160 kmph)
So a little higher max used speed then 65 mph is probbably not giving the overheated tire-material, but we cant exclude it.

Searched the 215/75R14 but only found ST,no LT , so cant compare if maxload is for lower speed given.

But GAWR being 2x maxload of OEM tires is done for linebusses too.
But those are not 100% of use loaded to GAWR as your TT is most likely.

Found also a D-load in ST with 108 loadindex is 2200lbs maxload wich would give the 10% reserve, and even a little reserve to full GVWR. But then dont use the recomended 50 psi as is max for C-load, you probably need the full 65 psi, and still things wont tremble loose from TT.

Theoretically you also then have to look if rimms are allowed for 2200 lbs, but reserves are that much, that it probably wont give failure of rimm, no caranties. And real weights on wheels where already higher probably, so the " overloading" was already there, and did not destoyed the rimms .

3 Things I keep in mind: anything you buy is manufactured to the absolute minimum in quality - don't believe anything you hear and only half of what you see - don't skimp on "important" stuff.
We once had a small 5th wheel RV that, by preference, weighed less than our truck, and the truck was rated to pull WAY more than the trailer. We replaced the worn D-rated trailer tires with E-rated tires. Never an issue with tires in +30K miles. FWIW from the peanut gallery.

I have a 2020 19ERD and my GAWR is 4000. My GVWR is 4384. The factory put load C.Tire size is stated ST205/75R14D. I'm assuming the D means load D. I had a blowout going 65mph. Wasn't a big deal. I put load D tires on it I've weighed my trailer while traveling and it comes it at 3878lbs.

We got away from trailer tires for the most part long time ago step up to a 225/75/ 15 if you can. Those are available in load range e. Finding any 14-in tires very difficult now. On our horse trailers, we have all moved up to load range and even into the 16 inch replacing the 15 inch. A light truck tires going to give you a stronger sidewall. The trick is if you have trailer rims getting a tire guy to put a regular tire on a trailer rim. I've been dealing with this for 45 years

(That is because) The GAWR us determined by tire weight rating x (# of tires); = Sounds like (maybe?) your sticker/ label is wrong/ was maybe one that was recalled? OR your rig came out of factory 500# over-weight? Might be worth a Tel/ call to Gulfstream? I have seen that issue on the RECALL LIST before for (various units/ various Mfrs. incl. GS) to replace with proper labels? OTOH, THE CURB WEIGHT IS LISTED AS ONLY 2847.
