Replacement 15 Inch Trailer Wheel with 5 on 4-1/2 Bolt Pattern Rated for 65 PSI

Question:

I have a 4700lbs travel trailer that I purchased and it currently has New 205 75 r 15 load d tires on 3 rims and one original 205 75 15 r load c. I also have a Load C as the spare. C is the original load tires the camper came with I want to match all the tires and rims and plan to purchase 2 new Load D and put on vehicle. I then want to use an older D for the spare so all will match. The 4 Original rims have no marking on them but he spare rim with the load C is different and has max psi 50 etched in on the rim. My question is Could I either replace valve stem and put load D on this rim and inflate to 65lbs as that is the load D tire pressure or do I need to replace the one rim? I I am not planning to over load the camper, but want to have all matching tires and tow at their max tire pressure, If I have to replace the rim to match my other 4 white spoke wheels then which rim would I need .

One option would be to go with all new tire and wheel combos. We have several options with 205/75-15 tires, load range D, mounted on wheels with 5 on 4-1/2 bolt patterns. There are aluminum and steel options and I have included a link to them for you. This will ensure that everything matches.

The standard wheels that you have can likely handle 65 psi but it sounds like the spare wheel may be unique so I would replace that one completely. For the other wheels, if you are changing the tires and keeping the wheels then you would have to replace the valve stems anyway and the valve stem is the limiting factor. I would just replace the wheel with # TTW550545WS1 if the others have an inside width of 5 inches (bead seat to bead seat). Or use # AM20522 for a 6 inch width and 3.19 inch center hole.

For a tire only I recommend # TR20515D. It is a 205/75-15 load range D and is rated for 2,150 pounds at 65 psi.
