BFGoodrich KO3 all-terrain is listed for the JL — 2018 through 2026

The BFGoodrich All-Terrain T/A KO3 is in and our fitment data lists it for one machine: the JL, model years 2018 through 2026. If you run a JL in that range, this is a direct-fit all-terrain option. If you run anything else — a ZR2, a Sportsman, an RZR-XP, an N300 — the KO3 is not listed for your machine here, so do not assume it carries over. A tire that fits one platform and model-year span does not automatically fit another, and the JL listing says nothing about any other rig.

What the KO3 is, plainly: an all-terrain tire. An all-terrain is the tire you pick when the same truck does the highway commute, the gravel forest road, and the occasional rocky two-track — it trades some of the dedicated mud tire's bite for tread life, quieter pavement manners, and better wet and winter behavior. If your JL lives on pavement during the week and sees dirt on the weekend, that is the category this tire is built for.

A few things we will not do in this brief, and you should be wary of anyone who does. We will not quote you a tire pressure, a load rating, or a size. Those are not style choices — they are matched to your specific JL's axle weight, wheel width, and how you load the vehicle, and the right numbers live in your service manual and on the vehicle's own placard. Guessing a pressure or a load rating is how you end up with a tire run outside what it was engineered for, which is a real safety problem at speed and under load, not a comfort preference. Read the door placard and the manual, or have a tire shop match the spec to your JL.

Fitment aside, a new tire size on a JL can change your effective gearing, your speedometer reading, and whether the tire clears at full stuff and full lock. If you are going up in size rather than replacing like-for-like, confirm clearance for your exact build before you buy — a lift, a wheel offset, or fender work all move that line.

Bottom line: JL owners, 2018–2026, have a fresh direct-fit all-terrain to consider. Everyone else, wait for a listing that names your machine. Pressures, load ratings, and sizes come from the manual and the placard, not from us.
