We had the same goals with our Puma 253FBS. It was about 3.5” out of level hooked to our F-350 4x4 and we wanted LT tires. I added a Correct Track system to raise the trailer 2” because there appeared to not be enough clearance above the tires while hitting a bump. Search for my prior thread on Correct Track before attempting. I bought new 16” 6 lug wheels (Dexstar—American made) that are rated for 80 psi load range E so they would fit on the existing hubs. Then bought BFG CompTA LT 215/85R16 Load Range E All Season tires which are rated at 2680 lb the same as the LT 225/75R16. We bought the taller thinner tire to get more height and now we are out of level less than .5”. That left enough space between the tires to get our Bal x-chocks in between the tires. We are well pleased with the final result. Remember that passenger tires are de-rated where trailer tires are not. Either of these LT tires would well exceed the 2540 lb. rating of the 225/75R15 trailer tires.
