I was looking at a picture of the Goodyear tires in the Owner's Manual for our '71 (p.16), and I can clearly see where it says "7.00-15LT", but I can also see the words "Travel Trailer", so what is the LT for then, if not for "Light Truck"?

Back in 1971 they had not cursed us with the ST tire yet. Instead they used Light Truck tires (7.00-15 LT) and put a notification that they were ok to use on travel trailers. Like mine (1984 31 FT Excella) that originally came with 7.00 15 LT tires installed you can go to BF Goodrich Commercial T/As or Michelin XPS rib in the size LT225/75R16 (new wheels required) without a fit problem. Just run the same pressure you are now running (60PSI).

In post 157 of this tread I had reported that Goodyear claimed to have moved the molds back to the US.

Today Goodyear stock went up noticeably when it was announced that the Government would not tax tires imported from China.

I now question the value of Mr. Marky's statement.

What I heard was that the US will put a tariff on Chinese made tires because China has been accused of dumping (i.e., selling tires extra cheap to get market share) tires here. China has threatened to retaliate.

I wonder if this will affect Maxxis? Aren't they Chinese made?

I'm sure it will affect them.

My biggest beef is that I cannot buy a locally made tire in this size in this load rating. I was at the tire shop last Friday ordering some BF Goodrich's for my wife's Trailblazer, and I asked the guy there what he had in a 235/75-15 in a Load Range D that would work on my trailer. He had nothing in stock, nor nothing available, at all.

If they go up 35%, I'll probably switch to 16" or 17" on the next iteration.

cheers,

Tires

Can you give us a little mor information off the sides of the tires or the name of the tire manufacturer.
I can't seem to locate them.

Prolex is a model of Maxxis tire.

It's also a flooring site. www.prolexflooring.com

I found it difficult to locate many Prolex tires on the internet and especially one in the 225/75R15 size. Looking in Consumer Reports, I see there are lots of tires I never heard of, many rated highly.

In the past few years terms like 8 ply and 10 ply have been supplanted by load range D and E (and others too). But now we are going to numbers, though it's not clear to me why. So, load index 110 equals 2,337 lbs.; 105, 2039 lbs.; 102 (common SUV tire and maybe load range C) 1,874 lbs. Load range D (2,540 lbs.) is equal to load index 113 (2,535 lbs.). I'm not sure of the weight rating for E load range, but I think it's around 3,400 lbs. Load index 123 = 3,417 lbs.

But these two ratings are different according to one website: "The load index indicates the maximum weight that a tire can accommodate vertically at a given PSI (pounds per square inch)." "Load Range is another way of indicating the ability of a tire to handle stress and weight. This time, we are indicating how much load can be placed on the tire horizontally. Often, these tires are associated with towing because the back end of the car tends to wallow while towing a trailer. In other words, you are exerting stress on the tire from side-to-side."

Since all we know is the weight of the trailer and not the horizontal loads, we are guessing and have relied on vertical load to determine what type of tire to put on a trailer.

This next quote comes from the Discount Tire site:

When purchasing or replacing trailer tires, look for the ST (Special Trailer) designation. Avoid using a passenger car (P) tire or light truck (LT) tires, as these do not have stiff, beefy sidewalls and other structural components to provide stability and handle the stress and dynamics imposed by a trailered load.
Modern ST tires feature materials and construction to meet the higher load requirements and unique demands of trailering.

"The major difference is reflected in the polyester cords used in ST tires," said Tim Fry, senior development engineer with Goodyear Tire & Rubber Co. in Akron, Ohio. "These cords are bigger than they would be for a comparable P or LT tire. Typically, the steel wire also has a larger diameter or a greater tensile strength to meet the additional load requirements.

"Because of the heavier construction for an equal volume of air space, an ST tire is designed to carry more load (than a P or LT)," says Fry.

What's more, the ratings on ST tires are standardized for axle ratings on trailers, according to Leo Garbarino, regional sales director for Carlisle Tire and Wheel Co. of Aiken, South Carolina. "If you have a 5000-pound axle, use an ST tire rated at 2540 pounds, so that two tires will meet the 5000 pound requirement in weight-carrying capacity," said Garbarino. "A P or LT tire is not rated the same way, so determining the load capacity can be difficult."


Isn't this fun?

Yeah, I would say so! So just how are the P or LT tires rated then?

Stingray, I think what it may mean is that ST tires are rated more for horizontal forces (load range) that's why we use the D and E ratings. LT and P for vertical and thus they are more likely to use the load index numbers. This is new to me, so I'm guessing.

'jim, "Post Quick Reply" or "Go Advanced" will get you to posting anything. After a while it'll come easier. Welcome fellow Coloradoan (or Coloradan).
