Travel Trailer Tire Choice
last fall we had a blowout on our way up to Lake George. We had the original tires on our 2014 Outback 250rs. Which I thought were good tires..at least as far as OEM tires go. the blowout occured...

Are you guys running the new heavy ply tires on the OEM rims ?
What are you doing about trying to match up the PSI ratings of the rims vs tires ? It seems like those 10 ply's are 80# psi ?
Are the rims rated at the same ?
how would you know what psi the wheel is rated for? I've never seen psi for wheels, just tires?
I found my Outback OEM aluminum wheels on etrailer and these are the specs they list:
Specs:
Rim dimensions: 15" diameter x 6" wide
Bolt pattern: 6 on 5-1/2"
Wheel bolt size: 1/2"-20
Pilot diameter: 4.25"
Offset: 0
Capacity: 2,830 lbs

Re C ply D ply or E ply : IMO, As long as your tires can support your max gross trailer weight on your axles then you should be good.
You have to go to a scale to know your real rolling down the road weight.
Wheels should be stamped on the inside somewhere with a psi #. You have to remove the tire in order to view it.
I just double checked the tires on my utility trailer and the last set were actually 15" D ply's. The OEM tires were C ply. I do not know what the psi rating is of my wheels, but the new ST D ply are working fine so far at 2000 miles with steel valves. Im running them 5 lbs under cold max at 60 psi.
I think its a good idea to balance the wheels. Some tires are out of whack more than others. Seems to me it would protect the wheel bearings a bit if it ran smooth.
