[A/S] Re: Overload Devices On Tow Vehicles

["nickcrowhurst" <NickandSandra@xxxxxxxxxxx>]

Harvey, many thanks for your reply, as intelligent as ever. I didn't 
weigh the trailer unhitched as the queue of semis behind me at the 
weigh station contained drivers who were already unimpressed by the 
delay I was causing! However, the unhitched weight of the trailer 
will be the weight when hitched (5680), plus the transferred weight 
(660) = 6340 pounds. The wrecked Argosy was towed by a pick-up, but I 
couldn't see any details. I am re-assured by your reply. The rig 
certainly tows beautifully with the current settings. There is a 
superb six page description on hitching up in Trailer Life magazine, 
May 2000. It is by far the clearest and most logical description I 
have seen, including the ball angle question. Your reply raises an 
issue about passenger car tires. My used truck came equipped with 
almost new P265/75 R16 tires with a maximum pressure of 35 psi. These 
have a max load of 2601 pounds each, so are capable of handling the 
static loads. However, the Dodge Cummins 2500 truck is plated for 
LT245/75 tires with front/rear max pressures of 65/80. Is there a 
stability reason here for changing to LT tires, and, if so, what tire 
pressure do you use? I suspect the LT tires will have stiffer side 
walls for better sway control, but as a visitor from overseas, all 
this is new to me. Nick
