That top one has 44 tires. Wow. Better be sure you have a nice long straight stretch before you try to pass that dude.

As far as tires, the first one actually has 86 tires total. 2 steer tires plus 21 axles that have 4 tires each.

Thanks for posting these pics - makes my tractor-trailer with one 53' trailer look tiny in comparison!

Also I find interesting are the 2 air intakes that are up high above the cab - I get to wondering what the reason is for that.

You're right! I multiplied the 7 sets of 3 tires each by 2 instead of by 4. 7x3x4+2 = 86
Checking tire pressure takes on a whole new meaning with this rig.

Cool images. Don't think they are allowed in California.

Great Shots Bruce... we have more and more B-Trains on the road which are quite similar... a tractor with a specialized trailer that has a fifth wheel for another trailer. It is so long front to back and with the hills and curves we have here on the two lane highway you want to respect the size and think twice before passing. I don't think I've ever seen one with three trailers. Thanks for sharing!

Hi,

The reason for the raised air intakes is that the air is cleaner when they move off the sealed roads and also cooler. At speed it also gives a ram effect to help with more power as they are only around 600 horsepower and they need every one of them.
I worked for a company where they used to gross four hundred tonsand the motors were running 100% loaded, 100% of the time.

Regards.

If you have a close look at the top photo Tess, that is a b-train towing two six axle dog trailers, the second photo is a triple road train. cheers

I don't think I could drive something that big, let alone park it. Do you even bother backing up in that?
