BFGoodrich KO3 All-Terrain now listed for the JL, model years 2018–2026

If you run a JL built between 2018 and 2026, the BFGoodrich All-Terrain T/A KO3 is now on the compatibility list for your machine. That is the whole of what we can tell you about fitment: this tire is listed for the JL, model years 2018 through 2026. It is not listed here for any other platform, so if you are on something else, treat this brief as information about the KO3 generally and check your own fitment before you buy.

The All-Terrain T/A is a well-known name in the category. For a JL owner, the practical appeal of an all-terrain is that it is a single tire you leave on year-round — street miles during the week, dirt and rock on the weekend — rather than a dedicated mud or sand tire you swap in. That is the use case to measure it against: how it behaves on pavement and in the loose stuff over a full season, not how it looks in a parking lot.

What we will not do is hand you a pressure number. Tire pressure on a JL depends on your tire size, your load, and whether you are aired down for a trail or running highway speeds, and the figure that is safe for one of those is wrong and potentially dangerous for another. The number that matters is the one on your vehicle's placard and in the service manual for the size you actually fit. The same goes for load rating — read it off the tire's own sidewall and the manual, not off a brief like this one. Guessing a pressure to "get close" is how you end up with a tire that overheats at speed or unseats on the trail.

A tire change on a JL is also a good moment to think about the parts around it. The JL has a healthy aftermarket, and shocks like the Fox 2.0 Performance Series IFP and wheels like the Method Race Wheels 305 NV are listed for the same 2018–2026 range, so a wheel-and-tire refresh can line up with a suspension plan if you are headed that way. None of that is required to run the KO3 — it is simply that the fitment windows overlap.

Before fitting, confirm the exact size clears your JL's flares and steering sweep, especially if you are already lifted, and have the new set balanced and torqued to the service manual's spec. If you are moving up in size from stock, check whether your build needs a re-gear or a speedometer correction for the new rolling diameter. Buy the size your build is set up for, and leave the numbers to the manual.
