Choosing Between ST and LT Tires for a 5th Wheel Trailer

Tire 16 st for a 30 ft 2slide 5th wheel weight is 9280

Yes, both special trailer (ST) and light truck (LT) tires can be used on a 5th wheel trailer. They are actually the only two types of tires rated for this use. The reason for this is that tires on a trailer will be subjected to much harsher conditions that require a stiffer sidewall. A condition in which passenger (P) tires are not equipped to handle. Please note there are two different light truck (LT) tires, ones with the LT designation after the wheel diameter (ex. 7.50-16LT) and ones with the LT designation before the aspect ratio (ex. LT275/80-16). The ones with the LT designation after the wheel diameter are the ones that can be used on trailers.
If you are in between a special trailer and light truck tire then try to think of it this way. The light truck tires are made for just that, light trucks but can also be used on trailers due to their sidewall capacity whereas special trailer tires are made specifically for trailers. They will perform better than a light truck tire in my opinion. The only real benefit I see of using a light truck tire is more tread patterns available which won't really matter when traveling down the open road. They are also more attainable locally.
If you can tell me what size tires are on your 5th wheel in addition to the recommend load range, I would be happy to recommend a particular option for you.

I recently purchased a 5th wheel trailer .. all the tires are over 12 yrs old .. so obviously they need to be changed .. they are ST225/75R15 .. I have heard that it is a good idea to change to a larger diameter & width tire that will meet clearance of the trailer .. What are your thoughts on that idea?
