Here at SimpleTire, our team has gone through the catalog and rounded up some of the best LT305/70R18 tires on the market today. We then used SimpleScore to assign a numerical value for the categories of traction, handling, and longevity for each tire, as well as an overall average SimpleScore for each.

1. Mickey Thompson Baja Boss A/T - Best All-Terrain tire

We’re going to kick this list off with one of SimpleTire’s best picks for an all-terrain tire, the Baja Boss A/T from Mickey Thompson. The Mickey Thompson Baja Boss A/T weighs in with SimpleScore numbers of 9.9 for traction, 8.8 for longevity, 9.5 for handling, and an overall average SimpleScore of 9.4. With an asymmetric all-terrain lug tread and Mickey Thompson’s innovative Extreme Sidebiter wraparound lugs at the shoulder, the Baja Boss A/T is a tire that’s right in its element in mud, loose dirt, gravel, or other difficult terrain and has the Three Peak Mountain Snowflake rating for severe winter service. The Mickey Thompson Baja Boss A/T is tough as nails, with a durable silica-infused tread compound and Powerply XD construction that features over 50% more denier cord in its reinforcement layers and is protected by a 50,000 mile limited manufacturer tread life warranty from the factory. Even with those unbeatable off-road credentials, the Baja Boss A/T is surprisingly well-behaved (and quiet) on the pavement, thanks to that asymmetric tread and an optimized contact patch.

2. Yokohama Geolandar X-AT - Great All-Terrain tire

Next up we’ve got another great all-terrain tire from Yokohama, the Geolandar X-AT. When it comes to SimpleScores, the Geolandar X-AT comes in at 8.4 for handling, 8.3 for traction, and 9.1 for longevity, with an overall average SimpleScore of 8.6. Tough and tenacious, the Yokohama Geolandar X-AT is a compromise that meets in the middle between all-terrain and mud-terrain design and performance. It’s designed with Yokohama’s damage-resistant HD-2 off-road rubber compound and Geo-Shield design package, a stable and durable design that incorporates multiple sidewall plies, dual sidewall protectors, high-turnup casing, and a full nylon cap. Traction gets a further boost with large shoulder blocks in varying lengths, combination grooves with a dense sipe pattern, and aggressive offset center blocks. The Geolandar’s ellipse-shaped contact patch is optimized for good handling and even wear. Yokohama covers the Geolandar X-AT with a 45,000 mile warranty.

3. Nexen Roadian MTX - Best Mud Terrain tire

The Nexen Roadian MTX is another great candidate for a tough mud-terrain tire, with SimpleScores of 8.1 for traction, 8.2 for handling, 8.5 for longevity, and an overall average SimpleScore of 8.2. The Roadian MTX features tough 3-ply reinforced construction with an aggressive mud-terrain tread that’s still surprisingly composed and easy to handle on pavement. The Roadian MTX is designed with a tough, damage-resistant tread compound for the roughest terrain and a dual sidewall design that lets drivers easily personalize the looks of their vehicles.

4. Nitto Recon Grappler A/T - Good All-Terrain tire

Let’s wrap this list up with a fantastic value in an all-terrain tire, the Nitto Recon Grappler A/T. The Recon Grappler A/T’s SimpleScore ratings break down as 8.3 for traction, 8.4 for handling, and 8.7 for longevity, with an overall average SimpleScore of 8.5. A combination of staggered shoulder grooves, zigzag grooves, and tread blocks give the Recon Grappler A/T dependable traction in all kinds of rough off-road situations. Its rigid design helps provide surefooted handling, in wet or dry conditions, and a mix of narrow and wide tread grooves helps to keep highway noise low by canceling certain frequencies and overtones. The Nitto Recon Grappler A/T is covered by a 50,000 mile warranty.
