Michigan allows up to 164,000lb GVW- with the right number and spacing and design of axles/tires.

Most of those lift axles are steerable and will track right through the turns with little or no scrub or fuss.

-p.

Some vandal would have a blast flattening all of those tires. http://i5.photobucket.com/albums/y18.../smilielol.gif

Yeah ten. :oops:

164,000 is just a suggestion. I haven't seen one yet come into a mill under 170,000 hauling pulpwood. Heaviest I ever saw was 193,500.

Damn, a quad axle swift trailer, I drive for swift and never saw one, though out in NY and Florida I have seen double 53's on the turnpikes

On a 8 axle trailer, 5 axles will usually lift. For running empty. And the older trailers didn't have steerable axles, so you had to lift all 5 axles to turn corners!

We don't have any 8 axle trailers here in ontario, but we do have alot of 5,6, and 7 axle trailers tho.
Also have alot of super b trains
3 axles on the lead trailer, 2 axles on the pup.

Some super B's also have a lift axle on both the lead and pup, making 7 axles total on the trailer.

Ontario does not allow double 53 ft turnpike trains, but quebec does and alberta does too i think. I have also seen turnpike doubles on NY thruway.

Ontarios max gross is 63 500 kg ( almost 140 000 lbs) without a permit.
usually a 5 or 6 axle trailer and tandem tractor

A regular tandem trailer and truck is legal for almost 86 000 lbs here in ontario too.
12k on steer, 37k on drives, 37k on trailer

Also we can run 20 000 lbs front axles and tires if we need to get front axle weights legal. All dumptrucks have 20 000 lb steers
