Load Range E vs G vs H for Trailer Tires: Which Do You Need?
Load range E trailer tires carry roughly 2,830–3,750 lbs per tire at 80 PSI and suit most utility and boat trailers. Load range G (14-ply, ~4,400 lbs at 110 PSI) and H (16-ply, ~4,805+ lbs at 120+ PSI) are for heavy equipment, gooseneck and commercial trailers where E-rated tires run at their limit.
Quick comparison
| Load Range | Ply Rating | Typical Max Load (single) | Max PSI | Common Use |
|---|---|---|---|---|
| E | 10 | 2,830–3,750 lbs | 80 | Utility, boat, car haulers |
| G | 14 | ~4,400 lbs | 110 | Gooseneck, equipment trailers |

How to choose
Add up your loaded trailer weight (trailer + cargo), divide by the number of tires, then add a 20% safety margin. If the result is within 85% of an E-rated tire's max load, step up to G. Based on our Orlando warehouse shipping data, ST235/80R16 load range E is the most replaced trailer size in Florida — most failures we see come from running E-rated tires at their ceiling in summer heat.
