Convert ST tires to LT tires

Hi everyone

How do you convert ST tires size to LT tires size? For example 235/80R/16 load range E to a light truck tire size.

What we actually do is choose a 'recommended' LT tire with enough capacity for the trailers axle ratings and that will fit under the wheel well.
As some have said a LT E in several USA brands with 3042 lbs capacity work great on 6k axles.

If your trailer has 7k axles then choices are limited to the Goodyear G614 or the Sailun S637 load range G at 3750 lb capacity and 110 psi.

Some with the heavier units upgrade to the 17.5" wheels and commercial grade LT tires.

One poster suggests we only give brand names with unacceptable tire sizes on this forum or only the trailer manufacturer can help and their the only source of replacement recommendations. Simply not the case.
Most experienced trailer owners know better than to call the trailer mfg and get the same OEM bad tire recommendation they put on their trailer to begin with plus some trailer mfg are not in production anymore. There is no requirement to contact any trailer mfg for replacing tires.

Your best source for a recommendation is a forum (and many others) like this with hundreds of trailer owners who have been through the tire replacement process for 30-40 years.

Now if we knew some specs such as your axle ratings/trailers GVWR we can give you some excellent tire choices.
