So my girlfriend asked me if I could tow her horse trailer with my 66 f100. I said sure but got to thinking. Are my standard load tires safe for this? Trailer weighs 2500lb Maybe another 1500lb with horse and tack.
check the load rate on the side wall. it will give you the max weight and pressure and then figure you trucks weight and the tounge weight..... short answer.... you shouldn't have any problem, just check your tire pressures.
