JIMNLINExplorer IIISep 01, 2023Assuming your 8000 lb trailer is a tandem axle....with those 15" load E tires at 2830 lbs X 4 tires = 11320 lbs capacity. A 8000 lb TT may have 10-15 % hitch weight = in the 1000 lb range leaving 7000 lbs on the trailers axles. Typically a over tired trailer with 11320 lbs of tire capacity may make for a rough ride but shouldn't cause any overloaded tire issues.
