AT 7500lbs GVWR, my trailer should be more than fine with D Range tires @65PSI
My question is: Since it is only $6 more per tire, is there any drawback to going with E (10 ply) tires? Overkill? maybe! but for the price of a 12 pack of decent beer why not?
this is just my opinion:
Due to the fact that your TT is only 7500# the "D" ply is enough or a little more than enough. The drawback 'might be' a harder ride or 'possible' premature bearing wear if the ride is too hard, which i suspect it will be, unless you deflate the "E" to 65# then what's the point, its the same as running a "D" at full 65#.
If your TT had a set of shocks installed, it 'might' mask the harder ride so you DO NOT feel it in the trucks seats, transferred through the hitch and frame . Remember the WD hitch distributes some TT weight thru/onto the truck.
At that point, if that should happen to you, then the gain to an overkill "E" was not worth the $24 and the "D" ply and beer would have the better option. :B
I would run the "D" and balance them correctly. Im not sure if trailer wheels are hub centric or lug centric but make sure the shop does a correct balance to match the hub or lug. That way you will NOT confuse any hard vibration of any beefier tire opposed to a unbalanced tire.
