duals or singles
For those have towed what are the benefits to duals vs singles. Like a dual tandem set up verses a tri axle? I know a few, a tri axle isnt the best for sharp turns and with the dual tandem setup you have 2 more tires to worry about. But what else is there? And Mr Tim Lamkin, i think i remember you having a tri axle trailer and wonder would you buy it over again?Pros cons etc. thanks for any and all answers.

with most tri axle setups i have seen each axle can carry 7000 lbs for a total of 21000 gvw for the trailer. Most tandum duals carry 10000 per axle for a total fo 20000 gvw for the trailer. I am wonder about stability, tire wear or any other pros or cons. The tri axles are generally cheaper due to cheaper axles.

The tires won't last as long on a tri-axle as they would on a tandem axle because of the drag when turning. Not only that, you have to buy 6 new tires instead of 4. If you can find a tandem axle well within the limits of what you want to do I would go that route. Using your example, the tri-axle only gives you an additional 1K.

Last time I checked, there were four tires per axle on a tandem dual, making it 8 new tires. Typically single wheel axles handle 7000 pounds per axle. Another consideration is deck hieght, depending what you want to do. You can get triple axle low decks, but cannot get dual wheel lowdecks, if this should matter. As far as general cargo hauling, highdecks are the most versatile because you don't have any obstructions, but the load sits higher, so more wind drag and higher center of gravity.

very true, not what I was getting at. Just making the point of tire number, not the fact that it will scuff the tires on sharper turns, not really that much to notice on regular highway running.Even tandem axles scuff a little on turns, and I admit that triples will scuff, but it really isn't a major problem unless you have sharp turns regularly.

i guess i have odd trailers then.
My PJ Dump trailer has brakes on both axles and my dads tandem dual tilt top has brakes on both axles.
I would have thought that a trailer capable of grossing 21k (lets say triple axle car wedge) would have more then 1 axle with brakes.

my triple axle horse trailer has six brakes, most tandems have both axles with brakes, the only time I have seen just one axle with brakes is on lightweight flatbeds. I can be wrong about this, but it is what I have seen.

The number of braking axles depends on how much $$ you want to spend on a trailer, and how cheap the manufacturer is. It usually only cost between 100-200 more to get brakes on the 2nd axle. Personally i want as much help stopping as i can get so i go with brakes on all axles.
