Depends on your wheel well opening... if you have dual wheels, it may prevent you from doing so. If you have any friends with those bigger tires and rims, see if you can try them on yours. OR...take very careful measurements!

I found this, not saying that it is correct or incorrect.
WHY 'ST' SPECIAL TRAILER TIRES?
These 'Special Trailer' (ST) tires have been constructed for better high speed durability and bruise resistance under heavy loads. Trailer tire construction varies substantially from automotive tires, therefore it is essential to choose the correct tire for your towing application. In general, trailer tires have the same load range (or ply) from bead to bead and are bias ply construction. This allows for a stiffer side wall which provides safer towing by helping to reduce trailer sway problems. The use of 'Passenger Car' (P) or 'Light Truck (LT) tires a on a trailer is not recommended because their construction, usually radial or bias belted, allows for more flexible side walls. This could lead to increased trailer sway and loss of control.

I think the last post is out of date. Most trailer tires are now radial in construction. My $60k+ fifthwheel (14k gvwr) came from the factory with Goodyear LT tires. They have given me very good service.
I think the best thing for stability would be go with higher load range tires and probably go up a size or two.
Good luck
