Back when we were children, we often used to notice other children playing with tyres, rolling them with sticks and challenging each other with who balances for a longer time. Did I give you a throwback to your childhood? Well, the real intention behind it was to make you aware as to how tyres were actually used back then in the old days.

Starting with the history of tyres, Charles Goodyear discovered vulcanised rubber in 1839, by adding sulphur, making it elastic and strong enough to be used as cushion tyres for cycles.

It was only after Goodyear, that pneumatic tyres were invented and patented by Robert William Thomson in 1845. After the era of Thomson, John Boyd Dunlop came up with the first practical pneumatic tyre which later became Dunlop tyres in 1888.

Just as people change with time, so did tyres after a point. Like for example, after five years or more in use, tyres need to be inspected at least once per year by a professional. Some tyres even have a span to which they can last. Normally, they last up to only 10,000kms or maximum 50,000kms, depending on the mode.

What holds the tyre on to the truck are the tyre beads that hold it to the rim or the outer edge of the wheel. These prevent the tyre from sliding out of place when the wheel rolls. The stability is provided by the bead filler.

Coming to the point, supposedly the truck driver is driving an 18 wheel truck and the total weight of the empty truck is 18,000lbs. Now, he puts another 18,000lbs of freight in the truck and the weight is distributed evenly on all the 18 wheels. When noticing the tyres, one would notice how much those are actually touching the ground, which is called the tyre patch. There might be 1 square on each tyre.

Now, if some math is applied, and 36,000lbs is divided by 18, the result would come up to 2,000lbs or 1 ton of pressure that is being pushed on to each tyre patch. Some roads even have certain restrictions regarding the weight the truck can carry and it is in the hands of the driver to know how much an empty truck weighs and whether the weight is evenly managed once the freight is transferred into it. This formula can be applied on every other human who decides to lose weight and has to be conscious about it every time.

In some cases, if the truck exceeds its weight limit, it instantly exceeds the per axle limit, so the extra wheels are lowered to make the truck legal.

One of the main reasons for semi-truck accidents is due to the sheer weight and size of these massive vehicles. 18-wheelers, tractor-trailers, and semis are often loaded down with large quantities of equipment which makes them the most dangerous type of highway collisions.

Truck manufacturers must mark their vehicles with an accurate GVWR, which stands for Gross Vehicle Weight Rating, visible on the truck’s license plate. A truck’s GVWR is marked with certain factors which include suspension, number of axles, powertrain, braking ability and frame.

An axle is what generates the tyres to lower down to give balance to the truck and make it legal. A non-driving axle, the ones used in heavy duty trucks and some two-wheel drive light trucks and vans, will have no shaft, and serves only as a suspension and steering component.

The overall weight of the truck is distributed with some ratio between the axles. A large contact patch is required, in order to keep the ground pressure within limits.By law, trucks are only allowed to carry weight up to a certain limit on each axle. A dead axle allows the truck to carry heavier load in a legal manner.

One more thing about axles is that when you pass through a construction site, somewhere toward the centre of the truck, a set of wheels are present that seem to serve no purpose at all. They are a foot off the ground and don’t serve any purpose goofing off while the other tyres are at work.Those tyres are part of what is called the ‘lift axle.’ They help to serve the purpose of an especially heavy load.

BabaTrucksTrucks are one of the most important cogs of the transport industry and are very good at distributing the weight of a payload more evenly than any other vehicle. It not only improves on its stability but also tows loads like horse trailers or large campers.

If it were not for these, transportation of goods wouldn’t have been possible and a huge part is played by the wheel and axle present in the trucks which allows managing weight on a daily basis.

To sum up, the main point of this article is to emphasize on why trucks actually have extra tyres, which many of us don’t know. And if you are wondering about where to look for the best quality tyres at the best price in the market, then you need to look no further than BabaTrucks. A dynamic platform for all your trucking needs, BabaTrucks helps you obtain the best deals for your truck tyres, along with great benefits such as insurance, truck monitoring systems, FASTag, and so much more.

Just like every individual has got something to say, even these trucks have history which is worth knowing and researching about!
