Computers are getting more intelligent, and with artificial intelligence, the advantages are clear of using machines versus people as drivers. The key is just to make it safe and reliable enough. With self-driving vehicles you can basically operate around the clock, to better utilize your investments. You can’t of course cut out all the people from your operations, but machines don’t get tired, they don’t need breaks and they don’t make mistakes due to fatigue or lack of concentration.
Self-driving equipment has been tried in quarries, where they
see a big saving on not having to fly in personnel to remote areas, higher
utilization of the equipment and much lower labor costs. Instead of having 4.5
mean per vehicle around the clock with time restrictions, you can equip it with
self-driving technology. For long haul trucks this has also been tested along
with self-driving cars. The technology is not far from being launched at a
bigger scale. Then we will have a lot more trucks driving around the clock.
The technology will not be cheap initially, until demand
gets really high, but the savings can be big from the get-go. It does require
that you can make sure that the equipment will run without breakdowns and that
the tires will withstand the constant wear. For the truck
tires, you will need to be able to effectively monitor the tire
pressure in all the haul tires on the rig and have a
procedure for how the trucks can stop for fuel and for tire monitoring. With
low tire pressure you will have higher tire wear due to higher rolling
resistance. Also the fuel efficiency is negatively impacted. Most of the tire
blowouts are due to low tire pressure, so it is a real and quite big issue.
This is a reason why you now and then see tire residue on the highways. The
trucks don’t notice the tire failure and continue driving.
For big heavy equipment used in mining, you will have big mining tires with extreme
conditions and you can easily have tire failures if the tires don’t have
continuous maintenance and check for cuts and cracks. This will be one of the
challenges for the future, how to make sure that proper maintenance is done and
to avoid tire failures.
If you think of the distances that a truck drives to deliver products all over the globe using the extensive road networks, it is quite amazing. Ships do long shipping distances between continents. They deliver containers, which can then be put on trucks for further deliveries. Once picket up at a shipping container terminal and placed on the semi-truck trailer, for land-based deliveries. They often still need to cover vast distances to deliver the full containers to a distribution center, where the deliveries can be done with smaller transportations unless there are full container deliveries.
The tires that are needed for these trucks tend to be long haul tires that are designed for
constant driving with good wear resistance and low heat build-up. You will want
tires that have low rolling resistance, so that your fuel consumption
will be low. Other good ways to save costs is to retread the tires. Retreading
can be done on a high quality carcass that is in good condition. If you don’t
have a high quality tire to start with then you can retread them. You can save
a lot of money by paying to have them retreaded, which can be done 1 to 2
times, if the carcass is in good condition before retreading. Retreaded
tires have excellent properties if the new tread is of high quality.
This is an environmental and cost efficient way to save money.
Since deliveries are a combination of time and money, you
want to make sure that your deliveries are not delayed. If your deliveries are
delayed due to tire problems, you will lose money in both ends. Both in terms
of penalties of delayed deliveries as well as extra repair costs due to
unscheduled downtime. Proper tire maintenance is always of utter importance to
make sure that you don’t waste money on taking care of problems that might have
been able to prevent. Tire failures are often due to low tire pressure, which
damages the tires. Since you have so many tires on a truck, the drivers often
don’t notice the problems, which is why you often can find debris from broken
truck tires on main highways. Checking tire pressure on all 18 or more wheels
can be time consuming, but can save you money in the long run.
Truck tires are some of the most used tires on the planet. Trucks have a lot of tires, normally 18-20 tires on each truck and they tend to drive almost constantly. So tire wear is significantly even when you use the most durable wear resistant tires, however these outperform any cheaper tire and you will be able to have more operating hours and less downtime with high quality tires. When it comes to commercial tires the tire costs tend to be small in comparison of what damage tire failures can cause as well as a lot of downtime, where you can’t utilize expensive equipment. So selecting a cheaper tire will never be worth it.
You need a reliable truck tires
that you know can perform regardless of what conditions that you will face,
without delays or problems. Customers rely on you to deliver their goods safely
and on time. Failure to deliver on time might incur penalties and it can even
ruin the goods if they are perishable. Depending on where your drive, you might
even need winter tires for your truck, tires that can handle snow and ice.
Without winter tires it is not safe to drive and you should not attempt it.
Attempting to drive without winter tires will surely increase the risk of
accidents and delays. It might also be illegal to drive without winter tires,
depending on where you drive, e.g. Sweden introduced last year a law that makes
it mandatory with winter tires for all heavy equipment driving on public roads
between 1st of November until 31st of March, something
that has already been introduced in Norway and Finland.
Durability tends to be key for haul
tires, as you don’t want to have tire related problems
during your drives. With durable tires, your tire maintenance should be
sufficient to ensure that the tires will last and will not wear out during
transport. You will have different tires depending on the position, where you
will have steer tires, drive axle tires and then trailer tires. It is important
to have good tires on all position to ensure that you have good control while
you drive and take turns. Low rolling resistance of tires can save you a lot of
money on fuel as well as retreading
tires, where a premium tire carcass can be retreaded
1-2 times to reduce both costs and environmental impact.
truck tires will wear out over time, you will need to replace them as the tread
wears out. With often 18-tires per semi-trailer truck, a whole fleet of trucks
will have a lot of tires to replacements every year.
proper haul tires mounted on your truck and the
correct tires for the correct position will reduce wear. There are specific
tires for the steer position and for the drive position and then separate tires
for the trailer.
pressure is also a factor that can impact tire wear, having under-inflated
tires tends to be the biggest contributor of excessive wear on heavy truck tires. Most of the blowouts of tires are
attributed to low tire pressure; it is also the biggest reason why trucks get
stranded on the side of the road.
in proper high quality tires reduces the wear and will give your fleet more
mileage out of the tires and less down- and tire servicing time. Higher quality
tires tend to have less rolling resistance, which reduces wear and lowers fuel
maintenance should still be done regularly to ensure that the tires are in good
condition and that the tire pressure is in the correct level. Perform visual
inspection, where you look for any damages to the tire and the sidewall. Measuring
the tread depth to ensure that it is above the legal limit should also be done.
of tires is built on the principal that the once the tread is worn out, you can
use the intact casing and add new tread to it.
quality retreading adds new tread with high safety and performance without
jeopardizing stability or grip.
Retreaded tires are a fraction of purchasing new
tires and can improve your fleets tire economy significantly.
Most trucks that are moving on our roads are semi-trailer trucks, they can carry heavy loads and can be loaded by containers from ships and then be driven across the continent for deliveries. With the containerization a lot of pressure has been put on quick deliveries by land with semi-trailer trucks. To distribute the high weight they tend to have 2 axels on the trailer and 3 on the tractor unit that pulls it. The steering axel has single wheels and the 2 drive axels of the tractor unit tend to have dual wheels and the same goes with the 2 axels on the trailer.
So when it
comes to the amount of tires on a semi-trailer truck you tend to have 18 wheels
with tires. You will have different tires for the steering axel position and
for the drive axel position versus the trailer tires. There are some
differences in the properties needed so make sure that you select the correct
tire for the intended position. You will have 2 steer tires, 8 drive tires and
8 trailer tires on an 18-wheeler semi-trailer truck. So getting a full set of truck tires can get quite costly, but you don’t
want to skimp on quality as that can impact your safety. Retreading
tyre can be an option,
if they are of good quality and the tire carcass is in good shape.
similar situation, there are a lot of tires, often with dual wheels in the back
and can have one or two axels, so the bus will have either 2 axels or 3 axels. Bus
tires don’t have the different tires for the different positions the same way
that trucks have and they usually have bus as part of the tire name. They do
though differentiate if it is city bus or a long haul bus, where city buses are
more durable for pavement impacts on the sidewall and the long haul are more
durable for long haul driving, where haul
tires are the right
buses and trucks there will is a need to have proper winter tires if you plan
to drive in areas where there will be winter conditions. You should have 3PMSF
symbol on the sidewall if they are approved for winter conditions. Some
countries demand that you have this if you will drive through them, others
should but they might no have that yet.
When you have goods that you need to haul for a long distances, it is important that you have good tires that will get you all the way, regardless of what weather you might meet along the way.
need to be designed for that extra mile as the cost of not getting to your
destination can be high. Depending where you drive and through what conditions,
you might need tires that are designed for winter use. If you will cross any
areas that have winter weather, you will need tires that are approved for
If a tire is
approved for winter conditions, it will have the 3MPSFsymbol on the sidewall. If your tires don’t have that symbol you
should avoid driving in winter conditions, you should even avoid driving in low
temperatures as the tires might become brittle
and crack under heavy pressure. Grip and control during winter conditions is
very important to ensure that the drivers and the goods being transported reach
the final destination safely. The tread is different for handling snow, ice and
slush. You need this special design to have the control you need, so make sure
that you have tires according to the conditions for safe long haul driving.
