What are r4 tires good for?

These tires offer excellent traction on harder surfaces, such as construction lots, and are less aggressive on grass than an R1 tire. An R4 tire is more aggressive than an R3 tire, however, it is less aggressive than an R1 tire. The depth of the R4 tread is approximately 70 percent deeper than that of an R1 tire. R4 tires, also known as industrial tires, are wide, durable tires designed primarily for use on hard surfaces such as pavement and gravel.

R3 tires, also known as lawn tires, are designed to minimize damage to turf with a shallower tread depth. These tires are usually a good choice for compact tractors that will be used primarily for mowing lawns or for working on lawns or gardens. R4 tires are sometimes referred to as “industrial” tires and share a composition and tread pattern common to tires used in industrial equipment, such as skid steer loaders and some forklifts. The tread of R4 tires has a barred pattern like that of an agricultural tire, but is thinner.

It is a multi-purpose tire that has a more aggressive tread than a grass tire, but less so than an agricultural tire. If the tractor operator is careful, an R4 tire will not destroy grass or dry surfaces and will distribute weight a little more evenly than an agricultural tire. Our next test will be the R4 industrial tire. Now, the R4 for us are by far the most popular tire option.

These are probably sold on around 90% of the tractors we sell and that's generally due to their good combination of durability and traction. Today we'll go to the load cell and see what it does. It's very interesting, I seem to have enough traction here, sitting on this ice with my grass tires to not be able to let go of them. So, while performing similarly on dry terrain, R1W tires perform better when the going gets tough.

To do this I will use the mid-range, which will give me enough traction to release these tires, but not as much as the low range, but it will overload my load cell. We're going to tear down three of Kubota's B series tractors, one with R4 tires, one with the new R14 and another with this zig-zag hybrid pattern that I've had for a while, connect them to the load cell and measure exactly what the difference in traction is between these tire options. You may feel that the dirt is a little damp here and it's probably fairly easy for these tires to come loose. They are not found in the type of traction environments that will benefit from the tire's aggressiveness.

There are two other tire options in this series, this small B series has five different options. Agricultural tires are mainly used for agricultural use, where the equipment will be used to navigate through and through the uneven and rugged terrain of farms, fields, etc. We will come back here and reconnect the bar grass tire here, because these results are much different from what I expected. Another factor to consider is the tire's tread design, which can dramatically affect performance.
