What type of vehicle uses 3.75-meter tires?
4 Answers
3.75-meter tires belong to large heavy-duty vehicles. The size of vehicle tires is an important factor in measuring the size and quality of a vehicle. Introduction to heavy-duty vehicles: Heavy-duty vehicles refer to M-class and N-class vehicles with a maximum gross mass exceeding 3,500 kg. This type of vehicle typically consists of heavy-duty tractors and heavy-duty trailers forming a vehicle train. They generally adopt multi-axle tandem hydraulic suspension systems and are primarily used for transporting oversized or overweight cargo that exceeds the limits specified by road traffic regulations. Vehicle curb weight: Vehicle curb weight, also known as "unladen weight," refers to the weight of a vehicle when fully equipped according to factory specifications (including spare tires, tools, etc.) and with all necessary fluids filled. Curb weight is a crucial design parameter for automobiles.
Wow, a 3.75-meter tire is definitely a super giant! Let me start by saying this size isn't meant for ordinary cars. Regular car tires usually have diameters ranging from half a meter to just over one meter. These nearly 4-meter-tall tires are exclusively for massive mining trucks, like the Caterpillar 797 or Liebherr T282 used in mines. These behemoths operate daily in muddy and rocky terrain, so their tires must be designed extra-large to withstand heavy loads and rough conditions—each truck requires at least six of these tires. I've watched documentaries online mentioning that a single tire like this costs tens of thousands of RMB, and maintenance is expensive too, requiring specialized teams. In short, if you ever spot such tires at a mining site, remember they belong exclusively to those mining giants—don't even think about trying them on a family car; they'd never fit in the garage!
As a seasoned professional frequently exposed to various vehicles, I've seen many tire details. Tires with a 3.75-meter diameter are primarily used in heavy-duty mining trucks, such as the Komatsu 930E series. These tires need to withstand loads of several dozen tons along with continuous impacts in rough mining environments—ordinary small-sized tires would burst immediately. In reality, such tires are made from special rubber and steel belts, making installation particularly labor-intensive and requiring large lifting equipment. Additionally, they aren't cheap; each replacement is a significant expense. However, the upside is they dramatically improve operational efficiency and safety performance. I advise car enthusiasts to steer clear of these giants—they're best suited for specialized applications only.
A 3.75-meter tire is quite an astonishing size, completely impractical for ordinary daily-driven vehicles. Generally speaking, these oversized tires are designed for vehicles used in mining or large-scale construction sites, such as those massive dump trucks. The reason for making tires this large is to distribute extreme weight loads and minimize damage to road surfaces. The diameter of a standard family car tire is less than one meter, and even an SUV couldn't accommodate something this huge and heavy. When I visited an auto show last time, I heard these tires have a short lifespan but come with high costs, requiring regular replacement. In short, if you encounter such tires, it's definitely related to heavy industrial machinery.
