Looks like the plane I intend to buy will need new trailer tires.
It's a Cobra trailer and the tires are size 175/80R13.
What are the latest trends and suggestions?
Light truck tires vs trailer tires, pro's and con's?
Going up a width or two in size, pro's and con's?
Thanks.

...I got a trailer tire from Les Schwab after the wife blew out one of the tires
driving the trailer over a curb (it is now the spare).

Apparently, trailer tires are pretty different from car or truck tires - FWIW.

Or further lessons required???
Just did this last weekend with my 2013 Cobra. Mine had OEM tires from Cobra which were Dunlop auto tires 175/70/R14. My tire guy couldn't get the exact same Dunlops (they were one of their middle-of-the-range Sport models) and we replaced with thesame spec tires from General. Drove them back to the gliderport at 65-70 mph and couldn't tell any difference from the originals.
P3I recently bought these tires for my Cobra Trailer-

"Bias ply trailer tires have a shorter tread life, but are built with a different
construction method intended for heavier loads." Wrong: The tire rating tells you how much
load a tire is intended to handle, NOT the construction.
"While LT tires may have thicker sidewalls and seem to make sense as an option, they still
are not designed to respond to trailer specific issues." Wrong: LT tires have a much
higher speed rating than ST tires (20 to 30 mph higher), and can easily handle trailering
side and braking loads.
"The load bearing capacity listed on an LT tire is designed based on the frame of a truck
– not the frame of a trailer. Wrong: the ratings are not based on the frame design, which
is not standardized for trailers or trucks. Trailers and light trucks do often have the
same solid axle design, which seems more relevant than the frame to which the axle springs
are attached. Also, Cobra trailers have an independent axle for each wheel, yet there is
no requirement to use a different tire.
Not mentioned in the article:
- ST tires generally have a 65-70 mph speed limit with the standard inflation pressures,
but can go a bit higher with higher pressures
- Bias ply ST tires have only one advantage over radial ST tires: they are cheaper.

America's Tire and Discount Tire have trailer tires for your rig.A tire can't be sold as new if it was molded more than 3 years ago.
For 13 inch wheels it may take a couple of days to get them in the store.
I find "trailer tires" have stiffer sidewalls and don't sway as much as automobile tires.
I also buy new tires every five years. Tires rot.

You never mentioned where you can buy LT tires that will fit a Cobra trailer.

Most trailer tires rot before wearing out. It seems like 5-7 years is about it for a "safe tire" before rot/cracks.
The date code is on one sidewall, it's molded in a oval about 1" long by 1/2" tall and close to the rim. It's 4 digits....the first 2 digits are the week of the year, the second 2 digits are last 2 digits of the year. So a code of "2321" is 23rd week
Just a tidbit. ;-)

specific meaning?
Michelin recommends 10 years as a replacement age limit on their tires. I don't know what
other manufacturers recommend.

I have had the best success with tires designed for trailer use - I believe this is due to the sidewall construction, since trailer tires aren't typically steered or driven like car or truck tires. Discount tire has always found me something suitable.Just a tidbit. ;-)I've always wondered what "tire rot" was. Is that a technical term? If so, what is the

Eric,than 5 years old did not tend to destroy trailer fenders on their way to wherever dead tires go when they die. There might be some sarcasm in the scientific claim in my first sentence, however that bar has been lowered significantly as of late, so maybe
John Murray did a very scientific study based on his sales of replacement Cobra trailer fenders, and asking questions as to how old the tires responsible were at the time of the incident. And if I remember correctly his data indicated that tires less

I've never understood the claim that nitrogen filled tires won't change the pressures with temperature as much as Air filled tires. Ideal gas law states that the relationship between Delta P, pressure change, is wholly a function of delta T,temperature change. There's no constant multiplier for different types of gas. Air, pure Oxygen, pure Nitrogen all behave like ideal gasses.
