Going from a 205 to. 225 tire
I was fixing to order some new load range D tires the other day to replace the cheap load range C that came on the trailer. I just happened to stop by storage and I am glad I did before ordering tires...

If the OEM 205's C's are on stock rim, it might be rated for 50# tire.
205 D = 65# .
Can a 65# tire be used on a 50# rated rim ? Just asking .
NO.
Tire and wheel mfg don't recommend it if your using 65 psi.
Having split trailer wheels on my flat decks in my younger dumber days when I ignored my tire dealer and mounted a 80 psi rated tire on steel wheels with a 60 psi rating...they split around the bead seat flange after airing to 80 psi and loading the trailer.
What happens is after the tires heat at highway speeds the 80 psi in the tire can go to 90 + psi.
Now you can use a 65 at 50 psi on a 50 psi rated wheel but you lost the benefit oif the D tire. The D tire needs to match the wheels width properly for best long term performance.
The benefit of a D tire comes only at those higher pressures.
Maybe I missed it but are you using 14" or 15" tire diameter ??
Thank you ,
I am running 205x15" . I Plan to get on a scale in the spring and weigh it all properly. As of now I don't have any issue running my OEM tires, im just looking down the road to upgrade a little for piece of mind. My TT is light, no slide, alum skin and not loaded up with stuff we never use. It only took us 40 yrs. to learn that. :)
