Most like "original" but there are a couple of tire and wheel combinations that work too. While you can dual up the budd originals with 9.00, it puts the width 2" beyond the legal 8'6". Bolster wheels like the M1061 has can work, using 12.5 x 16.5" tire or a hummer tire ( my favorite). Or you can use the M35A3 wheel and (???) tire. Or go to budds like the 19.5" (Isuzu rim) which comes in at 8'2" wide with 31" tires --- on tubeless rims. I'm not suggesting, just offering that there are a few options beyond the OEM reversed budd 2 piece rims.
They make great "parts" trailers too....bed, tongue, springs and frame mounts (bobbers), brake unit (for air over hydraulic), lights, axle (darn heavy).....if u are a fabricator (and "bobbed deuce" may be in your future).
I look around the nameplates for rust and old age. Clean and nice nameplate is indicator of the rest of the trailer.
