Strictly speaking about SMALL campers/trailers:

I am looking at a camper, Intech Flyer Pursue, they weigh 1300-17000 pounds...the current owner said the last time he weighed his fully loaded it was 2000lb. Brochure says 1195-1690 pounds, 300lb tongue weight, and GVWR of 2200lbs

Tires, its an off road model and it has what looks like cheap trailer mud tires on it that need to be replaces....is there a reason not to just buy LT or even P rated tires to replace them?

I get that ​​​​​on a larger trailer that weighs more it would be a slightly different argument

 

Trailer Tires should be ST rated as they are designed for trailer use (Let the arguments begin).
All arguments aside put the tire on you feel is appropriate and meets your needs.

 

yeah, I get ST tires are for trailer use and generally it makes sense as google tells me ST are built for more weight then their P counterpart but that’s generally because trailer tires are generally smaller or odd sizes and it’s normally difficult to find an LT. Plus, they generally hold a higher PSI and weight then a P or even an LT tire.

hence my question. For the odd ball campers like small pop ups or *off road* campers, as long as the tire meets the weight ratings, why not use it?

this one currently has ST rated “off road” tires that have the same tread as mud tires…

 

except for looks does the off road tread on a trailer tire even matter, especially in a trailer this light as I doubt it even has brakes. Just my thought, I have no experience with this.

Edit: I also see no reason not to run any tire that fits and has the load capacity, especially on a single axle trailer. I believe STs are designed to handle the side forces better when doing tight turns on a multi axle trailer.

 

ST tires will have less sidewall flex which is what you want. I would personally spend the money and go with Goodyear Endurance. The load D should be more than enough.

Im sure you could get away with an LT D and be just fine too. I probably wouldn’t use P metrics though.

 

looking at a social media site for the camper seems to point out that’s a recurring argument…most argue the stronger sidewall and better tread pattern help the trailer not slide and stay on track….I have no opinion on that, lol.

the tires that are on there are mud tires and are about $100 more per tire then an LT AT or MT in the same size

 

You haven't mentioned what size they are.

 

didn’t think the actual size mattered for the purpose of my question of whether a different type (LT or P) with the proper load rating would be a suitable sub.

but, I believe they are Mudstar Radial MT 235/75/15

having a rough time finding them online and the specifics, I don’t think they still use that brand in the newer models

 

Ive run LT tires on my trailers for years towing ~6500lbs.
I moved the axles slightly on my 24' long because the mfg half assed the assembly of the axles to the frame.

 

My trailer with that light axle uses these which is why I asked. Can't get P or LT in that size.
