Trailer Tire Speeding Rating??
Recently purchased the new-to-us TT in my sig. For piece of mind, I plan to replace the tires in the very near future. Current tires are Rainier ST235/80R16 Load Range E. Since this is not a large ...

Would I get anything more by going to an LT tire in the same size or assuming the rims can handle the extra pressure, moving up to a LR F or G tire? It's not my goal to fly down the road doing 80 but know 70 or so is safely doable in parts of the country where higher speeds are allowed. Trailer gross is 11,200, axles rated at 5200. My rims are the only unknown at this point.
You will gain more miles of service plus a much better hiway tire for a road trailer that sees lots of miles.
My trailer in sig weighs 11400 lb loaded for a extended stay sitting on 5200 lb axles. I use LT215/85-16 E at 2680 lbs X four = 10720 lbs.
My 11400 lb trailer has 2240 lb hitch load which leaves around 9100 lbs on the axles......or about 2300 lbs per tire. Sooo... the LT 215/85-16 E have plenty of reserve capacity. I'm getting 7 years and 52000 to 55000 miles per set at any speeds and no issues
The good old standby LT235/85-16 E at 3042 lbs capacity will give you 12168 lb capacity which is well above your trailer actual axle loads. I keep these on all my equipment trailers. Their good for any normal highway speed all day and all nite runs.
All ST or LT E tires area rated at 80 psi so your current wheels will work fine.
You don't need a 3500 lb rated tire and sure isn't any advantage of using a F or G class tire for that weight trailer (axle loads).
