Hard to Pick a tire for TT
I have asked general questions before on tires. It is easy to confuse me with all of the symbols and codes...I currently have: Radial ST 225/75 R15D (F-108)? They are 6 years old and we are head...

I am considering replacing them with LT tires.
My Trailer:
GVWR is 7900 lbs.
GAWR (each Axle) is 4,400 lbs.
Max Cargo is 1,460 lbs.
How do I choose the best match in a LT tire. I have tried looking at Tire Rack and michelin sites and it gets pretty confusing. Thanks for your help!
Your ST225/75-15 D are rated at 2540 lb each which is plenty of capacity for your trailers wheels and 4400 axles.
There simply isn't many 15" LT tires left anymore. Years ago 1/2 ton trucks/large wagons/vans used 15" tires so we had many sizes and load ranges to choose from for our trailers.
Maxxis has a commercial grade U-168 Bravo in a couple of 15" LT sizes that will work for 4400 lb axles.
Vanco 2 from Continential has 15" at 665 psi and 2469 lbs capacity that work great on 4400 lb axles. This tire is a euro all position tire for vans/trucks and trailers.
If you have to have a LT tire the best all around bet is move up to a 16" trailer wheel with a LT225/75-15 E or a LT215/85-16 E both at 2680 lbs capacity. These sizes are very common and just about every USA tire makers has them and they are available every where in the USA and Canada.
Most 15" trailer wheels I've seen with 6 lugs will handle up to 80 psi.
