Tyre Change … not small change

Not all off road tyres are the same, as we all know, but when it comes to the most expensive off road tyres, a tyre change is a bit of a specialist job.
So have you ever wondered how a quarry dump truck changes it’s tyres, either due to a puncture or wear & tear. When the time comes it is a bit of a job because that’s some mean sized off-roading rubber.

 

QUARRY TIRE-DAMAGE

 

Our 4×4 tyres are hardly on the small size and can be a bit of a handful when they need changing, but pale into significance when you compare to one of these monsters.

 

 

 

DUMP-TRUCK-TYRE

One of the largest dump trucks in the world is the Caterpillar 797, it has tyres that are nearly 4 meters tall, weigh in at 5.3 tons, carry 100 tons per tyre, contain 908kg of steel and enough rubber to make 600 small car tyres. The cost is a staggering £29.5 k each. You’re not going to get that job sorted with a wheel brace and a couple of tyre levers or even that tin of lighter fluid and matches.

Changing the tyre is completed with a large hydraulic arm and jacks. we even found a video from France of a tyre change on a smaller but no less cumbersome piece of rubber….
