On a recent trip to Wisconsin we blew a tire.
Ended up at a Cenex tire place in Ridgeland. This is what they sold us.
Hartland (made in China) , EXP Highway, Load E, Tread 5 ply nylon cord, Sidewall 4 ply nylon cord, Maximum Load single 1250 KG (2755 @ 75 psi cold), Maximum Load single dual 1120 kg (2470 @ 75 psi cold) 7.50-16 LT
We were in an emergency type situation and couldn't really shop around or get any advice. They swore that these were the tires we needed and were rated higher (more plys??) than what we currently had.
Trailer is an Exiss ES 307 SLQ. (3 horse slant with 7 foot living quarters)

Did we get screwed and are these tires safe?
thanks

In an emergency, anything that holds air is good. The fact that you made it home safetly made their purchase worth while. Did you buy one or a whole set?
If you bought one, I would replace it with well known brand and use it as a spare. There are many good tires available in the 16" LT series, available at many sources. The China brands are NOT noted for their longevity, and have been negatively discussed in many postings.

Be fastidious about maintaining the correct tire pressures. Normally I would recommend running a full 80 PSI, but your trailer isn't overly heavy and a lower pressure of 75PSI might help save the sidewalls if you hit a pot hole. Look for any sidewall bulges or cracks, thread delamination etc., anything that looks out of the ordinary. You may never have a problem with them, just keep an extra vigilance.
There are many brands of 16" "E range LT truck tires that will work well on your trailer. Michelin is well liked, along with Goodyear, Firestone, Bridgestone, Cooper and my favourite, Goodrich.

A while back I asked for help here and besides getting good advice I got the 10 ply load range E tires. My trailer rides so much better and I have peice of mind. For the time it took for the farm store to order them now I know why so many people around here take the Light Truck tires and the load range D's. I won't. My trailer ( used ) came with car tires. What I do know is so many people always blow out both tires. I'd rather up my chances with a tire that can hold more weight and hopefully get stopped before blowing both for sure. That's my story with tires.

I have a question on maintaining the correct tire pressure. I purchased 10 ply (E) tires this weekend and asked them what I should keep them at. They said to keep with what's on the door of the truck which is 55 for the front and 70 for the back. I drive a F250 Super Duty diesel. On the tire it reads PSI of 80 and a friend told me to keep the pressure to what the tires tell me not the truck so now I'm confused which one I should keep them at. I pull a 21' Sidekick aluminum trailer. Which one is right? I thought I might stop by our local Ford dealership and see what they'd tell me.

Do you remember the Ford Explorer/Firestone tire debacle? Set your pressure by the tire...NOT the door...

Paul, that an apples/oranges comparison. On all my Ford diesels, unless I have a load, I run 60lbs in the fronts, and 50lbs in the rears....single wheel.

If you do search, you'll find the question about tire pressures has been asked numerous times. If you access these threads, you'll find a majority of truck and trailer owners maintain their tire pressures, according to the tires' manufacturers' specifications, and not the truck manufacturers.
There have been exaggerated threads about how the center of the treads wear prematurely, with the outside edges not even being in contact with the ground at those pressures. Look at an unloaded radial tire with 55 psi and 80 psi, there is no visual difference in its shape. There are claims that at maximum inflation pressures, suspension components are damaged, the ride is unmanageable, the occupants will suffer, etc. etc. etc..
The vehicle manufacturers have their tire pressures stated, for a compromise between a good load carrying capacity and the best ride. When you're pulling and carrying five to ten tons with your most valuable occupants, you want the most capability and security from your towing equippment. As per the tire manufacturers, this is at their recommended pressures.

If I am loaded (GN), I run max on the trailer, max on the truck rear and minimum 75 on the truck front. This will give a rough riding truck unloaded, so if I do any long distance unloaded, I adjust to 65 on the front and 55 on the rear. Unfortunately, the door doesn't provide sufficient information. If you are in doubt, ask a couple of tire guys who have been in the business a while.

I have always run 60 in the front and 80 in the back as per the truck recommendations on my 2005 F-250 V-10. Are you all saying that I should run about 80 all around? I assumed that the higher pressure on the back was because there was more weight with the gooseneck in the back. When I got the truck new the dealership had put 55 PSI all around, I assumed they considered that air pressure appropriate for regular driving without hauling. I generally only haul with this truck but if I were to take a long trip without the trailer I would probably reduce the PSI to 60 all around. Is this not correct?

Have a question about trailer tires. As we just had a blow out on one of ours. The tire reads 80 PSI cold!! So that means the tire should be at 80 psi while its sitting and hasn't been running on the roads correct??
My is worried about them being over inflated once they start rolling down the road and get hot.

All stated tire pressures are measured at a "cold" reading. The extra pressure gained when the tire is heated, is calculated into the tire's overall rating. A tire's pressure measured when it is hot, can exceed the original cold pressure by as much as 10%- 15%.
A tire's pressure should not be measured for accuracy or serviced when it is hot, other than to establish that it has the minimum amount of pressure for its intended service. It is difficult to try to determine the exact amount of over pressure the tire should have at any particular time. This will vary by its loading, speed and ambient air temperatures. If a tire's heated pressure is reduced to a cold reading, it will become underinflated.
An underinflated tire can overheat, over pressure and cause the heavier sidewall/bead areas to delaminate and fail.
