Its going in a straight line. Its probably got best part a 500bhp engine with 1000nm of torque. Safe to say its handling wouldn't have been affected.

Did you notice what suspiciously looks like a the gear change...

But is it proof he knew?

There again, the number of times you get cut up be some twat joining from the slip road by overtaking on the inside and then cutting in too close, occasionally you feel like, nah, I'm not braking, not today.

Exactly my own thought. When the police caught up both were parked on the hard shoulder. I suspect the trucker knew eexactly what he was doing.

In this case he's probably right, if you watch the video the first pair of wheels on the trailer are raised. This is done to save fuel when towing an empty tank that doesn't need the support of all three axles to take it's weight.

actually folks,

if you know anything about the haulage business, you'll know that if a trailer has three axels the road tax for the trailer is less than for a trailer with two axels,

however, because of the possibility to raise one of the axels theoretically to save the tyres when running empty,

there is a possibility by which allegedly some operators might run loaded or empty on only two axels thereby saving tyres and road tax contribution allegedly

Amusing idea, but if you ran a tanker with axles up when loaded you'd wear out the tires that were on the road quicker, and if they didn't actually burst you'd almost certainly find something like the brakes or the suspension would fail. They don't put the extra wheels on for fun...

sorry Dad,

allegedly it happens

I'll get me coat

Based on simplistic physics, rolling resistance and friction are directly proportional to weight, so total wear would be the same no matter how many tyres you use. But in reality the physics of tyres is a bit more complicated than that, but that's where my first assumption would be.

Or you could look at the GMTV interview they use, thereby avoiding the annoying American newsreaders and advert

Cheers - thought about that but I'm far too lazy.

Not so, that equation presumes that the vehicle is travelling in a straight line. Take a look when at it when cornering; there is far more friction and skew with the wheels down. There is some passive steering on the axils but not enough to counter the tyre wear.
