We have been offering an L4 design for the C1091 (LSNT) in sizes 26.5R25 and 29.5R25 for 2 years now, but there are still very few people who are familiar with the L4.

First, what is an L4 tire?

As described on the pictures above, an L3/E3 tire is the benchmark for tread depth. An L4/E4 is generally 50% deeper than its L3/E3 equivalent while the diameter of the casing is the same. The diameter of the tire is therefore larger. As for the L5, the tread is 2.5 times thicker than the L3/E3, but its casing is smaller to keep a similar diameter.

 

So, what is an L4 used for?

The L4 is the perfect tire to reduce the per-hour cost of tires. Let’s take the example of a loader that works on a flat surface and loads finished products into a quarry, this tire will not heat up and has a lower depth/price ratio than an L3 tire.
