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...

My "C" rated OEM TT tires at 50 lbs. and my "P" rated TV tires at 40 lbs. work just fine.
My hope is the 65 lbs "D" rating will provide a bit more durability without jarring the TT interior.
TT axles are rated to 3500 lbs. nothing I do to the tires will change that.
That was my thought too. Having too hard a ride. We need to be careful adding too much rubber. These TT don't need any more help to rattle things loose. :)

My TT has two 3500# axles too and a 6500# GVWR .
my 205/75/15 C's (6 ply) have an 1820# x4 rating ....which is a little more than my axles.
In my case , now I see no point in upgrading the tires size or ply other than going to a more reliable brand .
I plan to weigh the TT to see how the weight is distributed over both axles, which I think is very important. There is no point in stressing one of the axles and 2 tires.
Im trying to get it as equal as possible, through loading it as well as hitching it. I will weigh each axle hitched up and NOT hitched up.
If anyone has handling issues or is having recurring tire issues (especially on one of the axles)and can't get an equal load over both axles by proper loading and correct hitch adjustments, it is possible for an RV shop to reposition an axle for you.
