I currently have a 3H 12LQ with a 4 ft mid tack. I use G rated tires and am very consciencious about maintaining the correct tire pressure and still seem to blow tires more frequently than I should or would like to. Is it common with the larger trailers to blow tires? I am thinking about downsizing to a smaller trailer if that would help the situation. At $317 a pop it can get expensive!

What brand are they? What air pressure do they call for? Do you have a lot of gravel road driving? You wouldn't happen to have a bent axle? That is an expensive and potentially dangerous situation, and solving it is an important priority, as you realize.

Also check the wheels! The wheel rating must meet or exceed that of the tire. We had a simular type problem and found not only the a couple of the wheels was rated lower than the tires but also found that the tires showed to be a 14ply rated tire but showed a load range F, but that is a 12ply tire!

A friend of mine has a sundowner and has blown lots of tires is a 4h LQ trailer and she always carries 4 horses she just bought the same tires that cam new on the trailer and one of them blew, her dad to go up on ply and try that might be to much weight on one of the axles.

For in GA 317 a pop is way high. I am in GA too south GA too and that is extremely high.
PM me if you want. There is a guy close to Albany in tire business that will put on some tires for you that are good tires. Many use them and they went out to NM this past summer with no problems and no tire failure.
Be cautious of your scrubbing the curb. A 16' shortwall trailer is pretty long. I have one myself. Yours is I assume with a 12'+4'mid. Dont look at the load range, that is a joke. Go by the number of ply's. I suggest using the amount of air stamped on the tire. Most shops will only put 30-50 psi in the tires. I run 125 psi in my tires. I have 16 ply tires with about 25000 miles on them with no problem. Several trips out west as well. They are rated load "H" but like I said that is not what you should look at.

Thx for the info. I believe that I use a 14 ply tire and run it at 110 psi. The trailer is extremely long and I am known to hit a curb or 2 :)). I will pay more attention. I still think that it may be easier for me to downsize in size as well.
???? A bit off topic but there is an 80 psi rubber snap in valve. In fact there are literally millions in use on 3/4 and 1 ton pickups at any given time.

Chadsalt ... The relevant passage in the article was ..." On some light truck applications, special "high pressure" valve stems may be required (refer to the pressure rating of the tires). Most passenger car and light truck valve stems are only rated to a maximum of 65 psi, so if the vehicle has high load tires it will require high-pressure rated valve stems. "...
I don't doubt there exists an 80 psi rubber valve. How does a person look at a rubber valve and know that it is designed for 80 psi? I do doubt that there are millions of tires inflated to 80 psi with the proper valve as you say.
All my 80 psi tires (generally load range E or better) that came from the factory were mounted on wheels with metal valve stems not snap in. My one ton p/u's (dually ) had load range D (65 psi max) tires from the factory and snap-in valves.
Does anyone on this forum have 80 psi tires with snap in valves? Consider this post a warning that your valves may be unsuitable if they look like typical rubber tire valves...
This manufacturer of valves specifies a max of 65 psi for snap-in. Their "high pressure" snap-in valve has a metal stem. I'll guess it has a reinforcement of some sort. It doesn't look like the typical black rubber snap-in valve.

(quote) Their "high pressure" snap-in valve has a metal stem.
Hospuller... Your truck and one that my FIL had in 2003 are the only Chevrolet duallys I've heard of that came with LR-D tires. That is, the 2001 and later trucks with 215/85R16's.
My 2001 Chevrolet dually came with LR-E 80psi tires and it came from the factory with snap in valves with a brass reinforcing sleeve. Don't know if it's right or wrong, that what the "Michelin Man" used again when I put new tires on it last fall. I keep them at 89psi the year round. Same valve stem on all the horse trailers except the trailer with 17.5's and the new Cherokee with the 16", 110 psi G614RST's.
Picture of a stem used by GM on 80psi/LR-E tires. TR600HP, metal stem/EDPM base. The TR600HP high-pressure snap-in valve stems are rated at 100 psi (6.9 bars) maximum.

Years ago, I had a 5H trailer that consistently blew tires, no matter what brand or pressure..then I upgraded the axles & never had another...cheaper than upgrading the trailer...just a thought you might look into.....Dottie

??? Since all "your" 80 psi tires came with metal valves you consider that an accurate picture of all trucks? How many could you have possibly owned? Doubt what you like, but I can all but guarantee when having tires replaced the high pressure snap in will be used, unless the owner requests the metal stems at additional cost.
A simple stroll through any dealers lot in the past ~10 years will show the snap in valves are by and large the OEM choice. It would be poor business practice to use a more expensive metal valve with 2x the necessary psi rating when the cheaper rubber valve is available.
Why do you think your dually came with D tires instead of E? This is not un-common on duallys. Load range D tires can (generally) make the front axle rating on class 2 and 3 pickups, but not the rear axle of a SRW. However four D tires WILL make the rear axle rating of a dually. All about saving a few $$.
So before there is a panic, the high pressure snap in valves are rated for light duty pickups (80 psi). They are identified by the brass tube sticking out of the stem, see above pic posted by retento.

There was a story on the news the other night about a recall on some of the rubber valvestems. The report said that the only way to check if you have a defective valve is to take the tire off the rim.
