Should be enough on there to whet your whistle
Tri-axles are extremely uncommon in the states. Most toll roads and bridges charge by the axle, so there is absolutely no incentive to run a 3-axle trailer unless you have some sort of blanket overweigh permit (as many fuel tankers here have). The percentage of 3-axle trailers in the states is less than 1%
Canada, OTOH, allows up to 60 Tonnes without special permits, and 3, 4 and 5 axle trailers are quite common. Up there, maybe only 50% of the trailers have only 2 axles.
thanks for the reply alex the pics i was lookin at were from a truck show in canada
Alexx is right, The only tri-axles I have seen in quantity are some flatbeds being pulled by Suttles way on down Southern Alabama, the drivers hated them because they couldānt be slid, were all super singles and as far as they were concerned had an awful turning radius

Ah, yes, the tri-axle southern flatbeds. From what Iāve heard, some companies use these because their drivers were too dumb to figure out how to even the axle loads out. In that part of the world, toll roads and bridges are rare, so the extra axle doesnāt cost too much more. With a max of 80k lbs, a tri-axle tridem can handle as much as 46k lbs. Makes running legal almost guaranteed.
The Pepsi fleet here use tri-axles and carry 100,000 lbs, also some of the bulk trash haulers have them

Well, that certainly makes sense, yes indeed, after all, it was in Alabama Iād seen 'em, and everyone knows, the majority of people from Alabama donāt have elevators that go to the top floor. It would be the perfect place to try out some no brainer trailers!, Cheers Alex.

Yes. Those have āR permitsā, and arenāt legal in all states (like PA).
Actually, on this end of the state, the Pepsi distibutor (Clintonās Ditch Distribution) uses only 48ā 2 axle trailers, but every one of them is set up to run as a turnpike double. On my way in today, I passed one pulling 2 empty 48āers, and he was holding 70 mph up the fairly long hill at Victor.
Most of the gasoline tankers in NY are 3-axle units as well, using the same R permits.
What the %&$# is an āR Permitā 
I keep seeing that sign āNO R PERMITSā everywhere, and each person I ask tells me they have no idea 
An R permit is for any truck that is over the STAA maximum weight of 40 tons.
Now, Pat, as a person who mustāve driven those typical ācontinentalā arrangement of a single screw and tridem trailer, let me ask you:
Do you think that a similar setup would work here in the US? In most states (NY being one), you can get 46k on a trailer tridem, 20k on a single-screw drive, and, depending on the width of the tyre, 14k or more on the steer. Add them up, and you have 80k, with a much more manouverable trailer. What do you think-could it work??
Could workā¦ you never knowā¦ Would be nice.
Alex, I donāt know why they donāt have them here Apart from the anti cabover thing.
I could turn a tractor/trailer over there on a sixpence, they are far more manouverable, especially with a rear lift axle
Ummā¦just how big is a sixpence, anyways?
Similar size to a dime mate 
And why do the Americans talk about weight in pounds?
A fat bloater who eats Wimpyburgers may weigh 300 lbs, but a truck that weighs 80,000 lbs. It is like shopping in Istanbul when you need 7 million lira to buy a cup of coffee
We hardly talk about trucks weighing 44,000 kilogrammes.
Whats wrong with an old fashioned ton? or even a metric tonne?
Tell you another thing as well,Theyāve never heard of a stone/cwt (Hundredweight) in weight terms neither.
ā¦or a Fortnight
Well, FWIW, Turkey has changed their currency, so now that coffee only cost 7, not 7 millionā¦
Iām still foggy on just how weavy a stone is, cwt is rarely used, but we mostly all know that a fortnight is 2 weeks.
Unfortunately, upon hearing a reading of Lincolnās Gettysburg address, when hearing the words āFourscore and seven years agoā¦ā most people donāt have a clue that this means 87 years.
There are 14lb in a stone and 8 stone in a hundredweight (CWT) and 20 CWT in an imperial ton.
