When I went to the Alberta oil sands for Business Insider last month it was hard to miss the biggest dump truck in the world: the Caterpillar 797B.
One of the many unique aspects of the Cat 797 are its tires: More than 13-feet-tall, weighing 11,860 pounds, each Michelin or Bridgestone 59/80R63 XDR tire costs $42,500 and that's when you buy the full set of six required by each $5.5 million truck.
They're one of the largest tires in the world and were made for the original Caterpillar 797.

Since Nokian Tires launched Nokian Ground Kare tires for wheeled excavators and backhoe loaders two and a half years ago, a lot has changed in how excavators do their jobs. The single wide block tread tire has proven itself in many earthmoving applications and this has made it so popular that Nokian Tires decided to expand the Ground Kare tire range on both sides: 600/50-22.5 for small excavators and size 710/40–22.
5 for the largest vehicles. nine0006
In 2019, Nokian Tires called its new Nokian Ground Kare tires the “golden mean” between the exceptional stability of dual tires and the excellent grip on soft ground offered by a single wide block tyre. Earthmoving contractors immediately appreciated the useful feature set and subsequently the excellent service life.
“Our Ground Kare tires are the best on the market,” says Kimmo Kekki, Nokian Tires product manager. “We were confident in their impressive performance, but their real value has been proven in everyday use.”
Winning features
A large number of contractors who previously used dual tires have switched to Nokian Ground Kare tires from Nokian Tires, attracted by their three main advantages:0005 contact patch, which minimizes soil damage during and after work, and single tire configuration , which, unlike dual tires, does not get stuck in stones.
“The tire faces many challenges on the job site. The Ground Kare tire with steel reinforcements is well protected against cuts and cracks, says Kimmo Kekki. “Moreover, the large footprint makes it extremely durable, both in terms of working time and mileage.”
Today, the work of contractors often requires the movement of equipment on high-speed highways. Ground Kare tires make these rides more comfortable.
“The Ground Kare tread pattern provides a smooth ride on the road for a quieter ride,” says Kimmo Kekki. “And a larger footprint contributes to slower, more even tire wear due to reduced and evenly distributed tire pressure.”
User reviews
User of Nokian Tires' Nokian Ground Kare tires Sami Isomyaki works on an excavator in Helsinki, Finland, mainly on construction sites. He used dual tires on his excavators before, but Ground Kare tires have proven to be more suitable for soft surfaces, especially loose surfaces like crushed stone.
“I used to have to use a crawler excavator on difficult terrain,” Isomyaki says. “Now with Ground Kare tires, I can work in places where dual wheels would get stuck.” Isomyaki also notes that the carrying capacity has become noticeably higher than with dual wheels. nine0007
New sizes, new possibilities
With two new sizes, owners of new types of excavators can now take advantage of Ground Kare tires.
“Size 600/50-22.5 is suitable for small and compact machines, for which these tires provide improved stability and better soil protection,” says Kimmo Kekki. “Size 710/40-22.5 is designed for the largest wheeled excavators that need a very large footprint and ease of use on construction sites with soft surfaces.” nine0007
Kekki is confident that Ground Kare tires will find new friends among both compact and heavy excavator users.
“Contractors have really discovered single wheels,” he smiles. “And our product has proven its effectiveness in various working conditions!” +358 10 401 Kimmo Kekki, Product Manager, Nokian Heavy Tires Ltd0007

Information about industrial and industrial tires nine0007
For over a decade, BKT has developed many different OTR radial patterns and sizes for specific applications and environmental conditions such as snow, mud and dirt, rocks, recycling or even underground mining. Production started with smaller loaders, then added rigid dump truck tires, and finally reached the Giant segment.
At the moment, BKT has over 40 tread patterns. And if you consider that each pattern has different sizes, you get more than 200 tires. nine0007
Every minute of downtime for a single piece of equipment, whether it be a mining truck, loader or any other mining vehicle, is considered a loss for management. Everyone knows that time is money.
About 30% of operating costs at large OTR facilities such as mines are invested in tires. Therefore, choosing the right tire is a critical factor for maximum life and maximum performance. Frequent failures, downtime and excessive tire changes are often the result of using the wrong tire for the job. nine0007
When talking about the classification of earthmoving tires, the standards of the two main tire companies are taken into account.
Each operation has its own TRA code - C-E-G-L, SH: compaction, transportation, leveling, loading and underground transportation. There are also sub-codes such as C1 or E1 which denote a smooth tread type or regular rib. The first is a tire for compaction, the second is for transportation. There are many specific types of tread, for flotation, rock pattern, etc., which are always combined with a specific operation. nine0007
Although different standards do not define different tread depths for any other code, which is in fact in the hands of the tire designer, there are general guidelines that allow comparison between different tread types from normal to very deep. BKT oversized tires comply with this general rule, which is important to know for specific applications. For example, junkyard work typically requires an L5 pattern code to improve puncture resistance and improve tire life. nine0007
According to ETRTO standards, tires for earthmoving machines are divided into three main groups.
These are narrow profile tires with a height to width ratio of 0.95, wide profile tires with a height to width ratio of 0.85 and tires of the 65 series with a height to width ratio of 0.65. Although in the OTR section, tire sizes are usually tied to specific equipment, the need for increased load capacity is an important issue. This explains the introduction of new sizes with a low height to width ratio of 65. nine0007
Basically, it all depends on the load index, the ply rate and last but not least, the so-called star rating, which is very typical in the world of OTR tires. The load index is the easiest way to determine the load capacity, a numerical code that is directly related to the tire's maximum load capacity in "kg". Although it is simple, it is not yet very common in the OTR world. It usually takes some time to switch to another encoding that people are not used to. For each type and size of tires, the load capacity is always associated with a specific tire pressure as defined by the ETRTO standards and the Manufacturer's Technical book.
The ply rating is primarily used for conventional tires and originally determined the number of plies in a tire carcass structure. Materials have changed over the years: cotton, viscose, polyester, nylon, aramid. The strength of the new cord has increased, and this has led to an overall reduction in the number of layers, but the coding has remained the same. The code is printed on the sidewall of the tire and determines the load capacity of the tire, not the actual number of plies. nine0007
While the load index we mentioned earlier is an absolute measure, the ply rate depends on the size of the tire, because at the same tire pressure you will get different load capacities with different tire sizes.
The star rating indicates the load capacity of OTR tires. Sometimes its use can be misleading. Remember that the load capacity through the star rating depends on the tire size, the tire pressure and the TRA marking with the so-called code codes E - L, etc. To give an example: A 26.
5R25**L4 tire has a different load capacity than a 26.5R25* tire *E4. It is not true that one star means less load capacity than a double star! It also depends on the type of application and tire pressure. nine0007
BKT always tells end users that tire maintenance is an important requirement, both in terms of efficiency and profitability. If tire maintenance is important in agriculture, namely a high power tractor (more than 250 hp) that weighs about 13 tons. Obviously their tires must be kept in good condition as they are used for heavy duty work. Now take a mining truck that has at least 10 times the power of a large tractor and has a load capacity of at least 250 tons. And it's fitted with huge 57-inch Giant tires. Now you can imagine how important tire maintenance is for such extremely large equipment that operates in difficult conditions.
