I. Introduction
In construction and earthmoving operations, equipment downtime directly affects project schedules and operating costs. As a key component, tire performance and reliability have a significant impact on equipment availability.
Forlander presents two new-generation construction equipment tires, designed to address common issues including premature tire failure, puncture damage, and cumulative costs over the service life.
II. JU4320 SUPER: Excavator Tire Without Spacer Ring Requirement
1. The Problem
Mobile excavators typically use dual-tire configurations to provide stability and load distribution. This configuration requires a dedicated rubber spacer ring between the tires to prevent stones and debris from entering the gap and damaging the inner sidewalls. This ring requires separate procurement, installation, and replacement, increasing maintenance costs and operational complexity.
2. The Solution
The excavator tire features a protruding kerb rib design on the sidewall, allowing the two tires to make precise contact and preventing stones from entering the gap.
Result: The rubber spacer ring is no longer required.
This reduces procurement and replacement costs, simplifies maintenance procedures, and reduces inventory pressure on service teams. A Korean tire supplier partnering with Forlander stated: “The elimination of the rubber ring is a significant cost-saving improvement that our excavator operators appreciate.”
3. Key Features
Directional tread lugs — extend to the center of the tread, providing off-road traction on loose soil, mud, and gravel surfaces
Extra thick void guard — provides tread impact protection, reducing puncture risk from sharp rocks and construction debris
Heavy-duty sidewall — enhances sidewall protection and stability, and improves operator comfort during extended operations
Wraparound stepped tread design — enhances self-cleaning capability, maintaining traction performance throughout the workday
4. Technical Specifications
| Size | Ply Rating | Type | Standard Rim | Overall Diameter | Section Width |
|---|---|---|---|---|---|
| 290/90-20 | 20PR | TT (Tube + Flap Required) | 8.00 | 1065 mm | 293 mm |
The 290 90-20 size is also available alongside 9.00-20 and 10.00-20 options, suitable for various mobile excavator models.
III. SUPER G2/L2: Heavy-Duty Skid Steer Tires
1. The Challenge
Skid steer loaders perform digging, loading, grading, and material handling within a single shift, placing multiple demands on skid steer tires: providing grip in gravel piles while resisting wear on hard surfaces; carrying heavy loads while withstanding rock and debris impact.
2. Key Features
1) 30% Longer Service Life
The heavy-duty skid steer tires use a new compound formulation and increased tread depth, delivering 30% longer service life compared to the previous generation.
For fleet operators and rental companies, tire life directly affects operating costs. A 30% increase in service life reduces replacement frequency, downtime, and total cost of ownership. The new formulation resists wear on hard surfaces while maintaining the flexibility and cut resistance required for off-road applications.
2) 10% Better Tread Impact Protection
Puncture and impact damage are the primary causes of premature skid steer tires failure. The SUPER G2/L2 employs two design features:
High lug-to-void ratio — increases rubber contact area to protect the carcass from sharp object punctures
Void Guard — reinforces the area beneath the tread to provide additional impact protection
Tread impact protection is improved by 10%, targeting the primary cause of tire-related downtime.
3) 310mm Extra Wide Profile
The SUPER G2/L2 features a 310mm extra wide profile, larger than conventional products in the same size class. Benefits include:
Increased contact area, improved flotation, and reduced sinking in soft soil, mud, and gravel
Enhanced stability, particularly during maximum load operations
Even ground pressure distribution, reducing damage to finished grades and sensitive surfaces
4) Rim Guard Design
Stones wedged between the sidewall and rim can cause wheel bending or cracking, increasing repair costs. The SUPER G2/L2 features an extra thick sidewall with rim-guard wall, preventing abrasion, punctures, and sidewall damage, and protecting the rim from debris impact.
3. Technical Specifications
| Size | Ply Rating | Pattern | Rim Type | Overall Diameter | Section Width | Tread Width | Tread Depth | Max Loading |
|---|---|---|---|---|---|---|---|---|
| 12-16.5 | 16PR | G-2/L-2 Super | 9.75 | 810 mm | 320 mm | 325 mm | 30 mm | 3075 kg |
IV. Product Positioning
In the engineering tire market, general applications are becoming increasingly specialized, and equipment owners are progressively recognizing tires as performance components. Tire performance directly affects productivity, safety, and profitability.
Forlander designed the JU4320 SUPER and SUPER G2/L2 to address specific failure modes: the integrated stone guard eliminates a component and its associated maintenance requirements; extended tread life reduces replacement frequency; impact protection features support continuous equipment operation.
Both products also reflect Forlander’s presence in the global engineering market. As the company participates in industry events such as Automechanika Dubai, demand for specialized construction equipment tires continues to grow, particularly in regions with accelerating infrastructure development. The JU4320 SUPER and SUPER G2/L2 address this demand, providing products that meet international standards.
