The tread depth of R2 tires is approximately twice that of R1 tires. R2 tires also have the widest space between the lugs to allow mud to come off more easily. Widely spaced lugs can show additional wear and cause vibration problems when driving. R4 tires are most commonly used in road or hard terrain applications.
They have a tread depth that is approximately midway between the depth of R1 and R3 tires. These tires are typically made of a more wear-resistant compound that holds up well on asphalt and dirt, making them the ideal choice when working between heavier work and turf projects. R-2 (R): for crops in extremely humid and difficult conditions. It is often called a rice and cane plant.
The tread depth of an R-2 tire is at least twice that of an R-1 tire. Until now, operators haven't chosen the R-1 with higher volume tires for larger tractors in drier regions, scraper applications, or larger float options for sprayers. That R-1W lug will grab more dirt and propel the tractor forward more effectively, while the area between the lugs will keep the tire on the ground surface. The main difference, defined by standards, is that the tab of an R-1W tire is 20% higher than the lug of an R-1.A variant of the R1 tire, known as the R1W, is designed for use in especially wet and soaked conditions.
Most John Deere tractors can be equipped with any of the three tread options, but that doesn't mean just any tire will do. Let's say you have a small 70-horsepower task tractor in your equipment yard, a loader in the front, or a box scraper in the back that doesn't even leave the farm. If a farmer travels long distances to reach his fields, or if the tractor runs in concrete feedlots, use an R-1W tire. It's important to consider the general conditions of your property and the accessories you'll use before committing to make a purchase, as each option will be optimal for different use cases.
Once you've decided on the right type of tractor tire, it's time to call local tire stores to find the best price. After considering soil conditions, think about how often the tractor will operate on paved surfaces, such as roads or concrete feedlots. If you think “tread” is tread and you don't need to know more than that to select a tire, you could end up with tires on your tractor, harvester, or other machines that don't work as well in their condition as they might. This is important because farms are now dispersed and tractors must be transported along roads to move between farms.
If farmers are concerned about soil compaction, it's more important to look at tire sizes or IF and VF tires that support the axle loads of their tractors at pressures below 15 psi. Whether you're buying a new tractor or simply replacing the tires on your current model, it's important to choose the right tires for the intended application, terrain and ground conditions.
