URAL-4320 OI-25 Weighted Wheel Set for Zimi Model

3D-Printed OI-25 Weighted Wheel Set for URAL-4320 by Zimi Model, 1/48 scale

To help your model of the iconic URAL-4320 truck look as realistic as possible, we created a series of highly detailed 3D-printed wheels with OI-25 tires, including 1/48 scale weighted option with a weight-bearing effect that recreates the natural compression of the tires.

The wheels are also offered in the following scales — 1/35 (Trumpeter) and 1/72 (Hobby Boss and ICM).

Maximum authenticity and detail
During development, we carefully studied photos, technical documentation, and available OI-25 wheel samples to accurately reproduce:

• the tread pattern specific to OI-25 tires;
• the shape and geometry of the rims;
• the sidewall relief and factory rubber texture;
• the correct deformation in the Weighted version.

Photopolymer 3D printing provides a level of sharpness impossible to achieve with standard plastic parts: crisp tread edges, clean transitions, and thin elements that withstand painting and weathering.

For military and civilian configurations
OI-25 tires were widely used on many URAL-4320 variants, making these sets suitable for:

• combat vehicles;
• transport versions;
• recovery and repair trucks;
• civilian or rescue configurations;
• dioramas where realistic stance and weight effect are important.

This is more than just an accessory — it’s a component that significantly enhances the character of your model and gives its appearance a finished, authentic look.

URAL-4320 — a legendary Soviet all-terrain truck

The URAL-4320 is a three-axle, all-wheel-drive truck that entered production in 1976 and became one of the most versatile platforms for Soviet military vehicles. Thanks to its diesel engine, high load capacity, and exceptional off-road capability, the URAL was widely used in:

• army units,
• engineering and logistics divisions,
• rescue services,
• civilian sectors where maximum reliability was required.

The URAL-4320 became a symbol of durability, mechanical simplicity, and the ability to operate in the harshest conditions — from deserts to arctic frost.
