Which eight LT tires?

There might be a good one now.

YEP, been running the 14" on my 7k tandem axle Boat Trailer for three years.

. I have always ran ST tires on my trailers and thought that LT were not supposed to be used although many do.

It is difficult to get over whatever BS they feed us on ST tires. Look into how tires are tested by our government. Full load at max speed. ST tires "CHEAT" by limiting max speed to 65MPH or 75MPH in some newer tires. LT tires are rated higher and the reason we have OEM speed limiters around 99 -110 MPH on vehicles: the full load OEM LT tire speed rating. So ST tires are a lighter tire because in theory they can carry the same load but at a reduced speed.

China Bomb is an earned name from defective ST tires that separate due to whatever reason the inexperienced "CHEAP" Communist Chinese tire makers have attempted. "We don't need that expensive step!" Tread comes off and $7000 damage to RV easy.

LT tires are enough trouble as it is ... Look at the Government Mandated Tire Pressure systems from the Ford Firestone Dead Body Pile.

You can be lucky. You can get the best ST tires. You also can get better LT tires that are rated at a higher speed for the same load range. ST tires at their load speed limit or a LT tire at it's load limit but a safety margin of 30 MPH to go before it heats up and fails... Speed+load = tire flex and heating.

I believe the points made about "other factors" are valid in the blog below. However he misses the boat in DE Nile and lands in the water over the plague of defective China ST tires. Haulmark had em piled to the roof at our local dealer in 2011 when we needed all 5 Hi-Run Communist China tires replaced due to separation. Including the spare that was never run. The spare went "BOOM!" in their shop.

I’ve never had an ST tire fail on the highway, but I’ve had multiple get flats on back roads. ST’s have softer tread and sidewalls so they are more prone to punctures. That’s my big reason for not running them.

ST’s will do a great job in most trailer applications, but not all.

That is interesting. I have some 15” ST tires on an agricultural implement and have no end of trouble with crop stubble puncturing the sidewall. I’m ready to get away from the ST tires there.

I can't count the number of ST tire failures I've had on my single axle boat trailer. No twisting, almost impossible to overload. I've never seen a 14" LT tire so I'm stuck with STs.

I wonder if the 14” ST are more prone to failures? I haven’t been around them, just 15” ST on an ag implement where they die from stubble punctures in the sidewall bulge and 16” ST on highway trailers where I haven’t seen problems with them.

I have heard the whole song and dance about how bad ST tires are; no doubt there were grounds for the complaints, and frankly I have been leery of them because of it. But at this point, I can only call it as I see it, and so far the ST tires haven’t been more troublesome than LT tires.
