You drive a lifted truck or a loaded SUV, and you want a 285/70R18 tire that grips gravel, snow, and mud without droning on your commute. Only two tires in this exact size are worth your money: one is the tough, dependable all-rounder, and the other is the aggressive-looking highway tire that punishes you off-road. Your choice depends on where you actually drive.
I’m Min — the founder and writer behind Gadgets Feed. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Every brand shouts “all-terrain,” but few publish the numbers that matter here: tire weight, sidewall construction, and treadwear. That is why every pick here is stripped down to the specs that actually matter for a 285/70r18 all terrain tires.
Our Picks at a Glance
How To Choose The Best 285/70R18 All Terrain Tires
In this size, the numbers on the sidewall decide how the tire carries weight and clears obstacles. The 285 is the width in millimeters (the cross-section from sidewall to sidewall), the 70 is the sidewall height expressed as 70% of that width, and the R18 means it fits an 18-inch wheel. Every tire here matches that exact string, so your real decisions are elsewhere.
Load range and load index come first
Your load index is a code for the maximum weight a single tire can carry, and load range is the thickness class of the tire’s body plies. A higher index means the tire is built stiffer and holds up better under a full bed, a camper, or a trailer. Both picks here share a 3,525-pound load capacity, which is the number that decides whether your truck stays safe when it is loaded.
Then match the tire to your actual road
An all-terrain tread trades mud grip for highway quiet and tread life. It gives up some mud grip compared with a dedicated mud tire, and it gives up some quiet compared with a pure highway tire. Decide which side of that trade you drive on: mostly pavement, or mostly dirt and gravel.
Quick Comparison
In‑Depth Reviews
1. BFGoodrich All-Terrain T/A KO3 Car Tire for Light Trucks, SUVs, and Crossovers
A 32.6-inch all-terrain tire that grips gravel and snow yet stays quiet enough for daily highway driving
If your truck splits time between a dirt access road and the morning commute, build around this tire. The KO3 measures 32.6 inches across, a full 6.6 inches taller than the Nitto Ridge Grappler’s 26-inch diameter. That extra height lifts your differential (the gearbox that sends power to the wheels) and running gear up out of the ruts instead of dragging through them.
What wins people over is how planted it feels in the ugly stuff. Owners talk about deep snow traction like it is a given, and the serrated shoulder design paired with mud-phobic bars is the reason the grip keeps biting when the surface turns loose. The CoreGard sidewall — a reinforced rubber shield over the tire’s outer skin, first used on Baja race trucks — takes the sting out of trailside rocks that would otherwise slice a softer tire open. You also get a 50,000-mile manufacturer’s treadwear limited warranty and a 6-year standard limited warranty behind it.
Here is the catch, and it is a fair one: this is an all-terrain tire, not a mud tire, and buyers report it gives up grip in thick, deep mud compared with a dedicated mud tread. It is also the pricey end of the pair. An owner running these on an F350 summed up the ownership experience plainly: “smooth ride, quiet ride, aggressive looking for sure.”
Where The KO3 Pulls Ahead
- 32.6-inch diameter clears obstacles the 26-inch Nitto can’t
- CoreGard sidewall shrugs off rocks that split weaker tires
- Deep-snow grip owners describe as a non-issue
- Quiet enough to live with on a daily highway commute
Worth Knowing Before You Buy
- Only 124 load index, two steps under the Nitto’s 127
- Weak in deep mud — it isn’t a mud tire
- Height can rub without a leveling kit on some trucks
- The higher-price option of the two here
Reach for this if: your driving mixes snow, gravel, and highway miles and you want a tire that looks as mean as it holds.
Think twice if: you spend real seat time in deep mud — that is the one surface this tread gives ground on.
2. Nitto LT285/70R18 127/124Q E/10 RIDGE GRAPPLER BW
A highway-quiet tire with an aggressive parked look and a 127 load index for heavy trucks
The Ridge Grappler is the tire you buy when your truck wears the look every day but only leaves the pavement on weekends. Its reinforced block foundation is a stiffer base under the tread lugs (the raised rubber blocks that grip the road) that cuts down on the squirm you feel through the steering wheel. That is the engineering behind what drivers describe as a pleasant, planted highway ride.
You get the highest load index of the two here at 127, which puts it a full three steps above the BFGoodrich KO3’s 124. That rating, combined with an 80 psi maximum pressure, is aimed at heavy trucks — the kind of rig that hauls a loaded trailer and needs the tire to stay cool inside. Sidewall to sidewall it also checks in at 59.9 pounds versus the KO3’s 57.4 pounds, so you are turning roughly two and a half extra pounds per corner.
That extra weight is the honest trade. Owners love how quiet and smooth it rolls, but a heavy-truck owner who racks up fast daily miles on a curvy half-dirt, half-pavement road reported the tread wearing out at 6,500 miles and did not plan to repeat the purchase. Snow and mud grip also take a back seat to the KO3, so go in with clear eyes on that.
Big-truck strength: the 127 load index and 80 psi ceiling are built for Silverado 3500-class hauling where the sidewall has to stay rigid under a full load.
Know your mileage: fast, mixed-surface daily driving on a heavy truck is the exact scenario that shortens this tire’s life, so highway mile-savers will get far more out of it than hardworking rigs.
Buy this one for: a heavy truck or SUV that logs quiet highway miles, wants the tallest load rating in the size, and likes the chunky parked look.
Look past it for: a light truck that spends half its life in snow and gravel — the KO3 out-grips it in both.
Understanding the Specs
Load Index and Load Capacity
The load index is a number code for how much weight one tire can carry, and the load capacity is that weight spelled out in pounds. Both picks here are rated to 3,525 pounds per tire. The BFGoodrich KO3 carries a 124 index and the Nitto Ridge Grappler a 127, and that higher number means the Nitto is built to run cooler and stiffer under heavy loads. If you tow or haul, this is the first spec to check.
Tire Weight and Overall Diameter
Tire weight is the literal mass of one tire, and it changes how quickly your truck accelerates and how much fuel it burns. The KO3 weighs 57.4 pounds and the Nitto 59.9 pounds. Overall diameter is the tire’s height, and it decides your ground clearance — the KO3’s 32.6 inches sits noticeably taller than the Nitto’s 26 inches, lifting your axle and helping you clear obstacles without scraping.

Final Thoughts: The Verdict
For most people shopping for the 285/70r18 all terrain tires size, the winner is the BFGoodrich All-Terrain T/A KO3. Its 32.6-inch diameter clears terrain the Nitto can’t, the CoreGard sidewall holds up to rocks, and the 50,000-mile treadwear warranty backs the toughness claim. If you want the tallest load rating in the size and prioritize a quiet, planted highway ride on a heavy truck, reach for the Nitto Ridge Grappler. Just set your expectations for mileage if you drive it hard on mixed dirt and pavement.
