R4 tractor tire, Meaning, Unique Features, and Size Chart

Meaning of R4 Tractor Tire

The R4 tractor tires can be described as depth-threaded and lug space industrial tires designed to be used in areas associated with hard surfaces (i.e. stony, concrete, and hard soil).

 The R4 tires like every other tire made with natural and synthetic rubber, have unique qualities that differentiate them from other tires.

These qualities are based on the lug space and deep thread pattern of the tire which make them excellent options for performing tasks on hard surfaces and stone.

 This strong nylon-made Industrial tire usually has a trending pattern or design written by the side to depict the type and nature of the tire.

The code on the tire is usually referred to as manufacturer’s code or industrial code which is available in all industrial tires.

This shows the types of work the tractor tires are built to perform, and all the tractor tires available in the market have certain codes that differentiate them from each other.

The R4 tractor tire comes in between R1 and R3 tires based on the treading, the depth, and the lug.

These codes scripted on the tire to a large extent have many significant influences on the overall performance and stability of the tire in different forms and geographical areas.

The R4 tractor tires have good traction which addresses the environmentalist concern that the tractor tires lead to the destruction of the soil, soil compaction, and soil structure.

When researching the best tire to be used for road construction, movement on the rocky, and working in stony environments, the R4 tire is the best shop due to its wide lugs and deep traction that ensure optimum durability and longevity when working hard surfaces.

Additionally, the R4 tire is most suitable for industrial uses because they are made with special rubber compounds and a nylon-cord body that is not easily worn and torn.

Unique Features of the R4 Tractor Tire.

The following are the unique features of this Tractor Tire.

1. Durability: the R4 tire possesses wide lugs that ensure longevity and durability. This quality makes the tire a good choice for construction sites, and building projects. The tires are well built with high-quality natural or synthetic rubber and a nylon-chain body that provides excellent impact and is resistant to wear and tear.
2. Rim Guard Sidewall: This particular type of tire is well equipped with a good side rim guard that can effectively minimize damage to the tire and rim. The tire sidewall is an additional layer of rubber on the outer surface of the tire that helps to protect against damage by rough and hard surfaces. This extra layer of rubber helps to keep the tire firmly to the wheel when working on a challenging terrain. 
3. Good Tread Pattern: The R4 tractor tire is designed with a well-treaded pattern and tire traction that ensures the stability of the tractor. The tread pattern particularly provides unique features that are beneficial to the users. It is a tire of distinct traction and thread for good floatation.   These unique characteristics of the tire tread design show the ability to provide traction on snow and hard surfaces. Similarly, the tire has excellent traction and the tread, which makes it have the aggressive ability to hold the soil firmly. The tire has a good rubber casing built on its lugs and numerous layers to prevent lateral damage and puncture.  The several layers on the flank help to enhance durability and make a good choice of tire for snow and ice traction.
4. Ability to Carry Heavy Loads: The R4 tire is manufactured using sturdy rubber, with severe metal bands to reinforce the tire during the production process to give the tire the ability to carry a heavy load. The well-fitted wheels help to hold the tire together while carrying a heavy load, thereby preventing wearing and tearing. Design with high load-carrying capacity, and maintain strong inflation pressure when working in the industries and road construction. This type of tire is ideal for load-carrying vehicles while on a work site or over long distances across rough terrain. The tire is well reinforced to cope with high pressure and resist any damage by heavy load.
5. Multifaceted Tractor Tire: The R4 tire is a versatile tire designed to be used for farming and industrial settings. It is efficient and suitable on the roads, in the farmyard, or in the fields, making it a multipurpose tire. The tire is designed to be easily maneuverable in the farmyard and also provide good traction in the fields. Its technical and innovative design ensures longevity and versatility.  The R4 tire is a great choice beyond farming operations due to its self-cleaning, ability to be used in building projects or building construction work, and other industries activities that require heavy load carrying. it is ideal for sharp turns on a hard surface.

Difference Between the R1 and R4 Tractor Tire.

Agricultural tractors are usually different from each other even though the tires seem to be similar. However, tractor tires differ according to model, brand, and tread design.

The tread design has a significant impact on the optimal performance and durability of the tire. Some of the notable differences between the R1 or Ag tire and the R4 tire are shown in the table below.

S/no	R1 or Ag Tractor Tire	R4 tractor tire
1	They are used especially in wet and muddy areas.	They are used in hard surfaces such as road construction, concrete areas, and stony environments.
2	They have wide-spaced lugs that help to prevent them from slipping or clogging.	They have depth tread and lug spacing for excellent performance on a hard surface
3	They are majorly agricultural tractor tires used for tilling and performing various agricultural operations.	They are multifaceted tires. I.e. use for various operations ranging from agricultural and non-agricultural operations.
4	They are the best option for tires to be used for working in difficult environments such as muddy, wet, and soil with soft structures.	They cannot be used for working in difficult environments such as muddy, wet, and soil with soft structures  like the  R1
5	They cannot be used for  carrying heavy loads over hard surfaces like the R4 tractor tires	They have strong sidewalls (additional rubber) which provide  supporting functions to the tire in carrying heavy loads over hard ground
5	The R1 tires can easily wear when they are used frequently on hard surfaces	They have well-positioned sidewalls that prevent damage to the tire due to tearing and wear.
6	The R1 tires are narrowly threaded	the R4 tires are deeply treaded
7	The R1 tractor tires are low budget hence, they are cheaper to purchase.	They are more capital-intensive, hence  they cost more than the R1 tires

R4 Tractor Tire Size Chart

Tractor tire sizes are different from one another, even if they are the same grade and type.  The R4 tire comes in various sizes, types, rim sizes, tread patterns, maximum load capacity, and inflation pressure (i.e. the air pressure).

The table below provides useful details of the requirements that buyers or users may seek to be better informed on the types of tires that they may want to purchase for their farm or business.
