Falken Wildpeak A/T4W: The Complete 4Runner Owner's Guide
The Falken Wildpeak A/T3W was the all-terrain tire that proved you didn't have to give up highway comfort for off-road grip — and it became one of the most common tires in the 4Runner community because of it. Its successor, the Falken Wildpeak A/T4W, keeps the same idea and fixes the A/T3W's weak spots: tread life, towing stability, and sidewall toughness on the LT sizes.
The short answer: if you're replacing worn A/T3Ws — or shopping your first all-terrain for a 4Runner that splits time between pavement, dirt, and snow — the A/T4W is the easy default pick. It's three-peak mountain snowflake rated in every size, carries up to a 65,000-mile treadwear warranty, and comes in the exact sizes 4Runners run, from stock 265/70R17 to the popular 285/70R17 upsize and the 6th gen's 265/70R18.

What Changed from the A/T3W
The A/T4W isn't a rebadge — Falken reworked the tire around the complaints people had about the A/T3W, mainly towing stability and tread life. Here's the short version:
| Wildpeak A/T3W | Wildpeak A/T4W | |
|---|---|---|
| Treadwear warranty | 55,000–65,000 miles | 60,000–65,000 miles |
| Sidewall | Mostly 2-ply | 3-ply DURASPEC on select LT sizes |
| Snow rating | 3PMSF | 3PMSF |
| Towing stability | Good | Improved (stiffer construction, Heat Diffuser technology) |
| Wet traction | Good | Improved (full-depth sipes) |
| Weight | Lighter | Heavier |
The trade-off for the tougher build is weight — the A/T4W is heavier than the A/T3W, which can cost you a little fuel economy. And if you find A/T3Ws on clearance, they're still a solid tire. But for most buyers, the A/T4W is the better all-around package.
One important note from Falken: don't mix A/T3W and A/T4W tires on the same axle. Differences in construction and tread design can unbalance handling and traction — if two of your A/T3Ws need replacing, Falken recommends a full set of four A/T4Ws.
Sizes for Your 4Runner
These are the A/T4W fitments that matter for 4Runner owners. Weights and diameters are Falken's published figures as listed by Tire Rack; Falken's own size sheet runs a pound or two different in a couple of sizes, so treat the weights as close, not exact.
| Size | Load | Diameter | Weight | Best for |
|---|---|---|---|---|
| 265/70R17 | SL (115T) | 31.7" | 46 lbs | Stock size on most 5th gens — the default replacement |
| LT265/70R17 | E | 31.9" | 53 lbs | Stock size with a heavier-duty carcass for towing and rocky trails |
| 285/70R17 | SL (116T) | 32.8" | 53 lbs | The popular "33s" upsize for lifted or leveled 5th gens |
| LT285/70R17 | C or E, DURASPEC 3-ply | 33.0" | 67 lbs | The toughest 33" option — for rigs that see sharp rock regularly |
| 265/65R18 | SL (114T) | 31.5" | 47 lbs | Stock size for 18-inch-wheel trucks like the 4th gen Limited |
| LT265/70R18 | E | 33.0" | 56 lbs | Stock size on the 6th gen TRD Off-Road, TRD Pro, and Trailhunter |
5th Gen (2010–2024)
Most 5th gens — SR5, TRD Off-Road, and TRD Pro — left the factory on 265/70R17, and the A/T4W in that size is a straight swap at 46 lbs a corner. The LT version costs you 7 lbs per tire and some ride softness, and buys you a stiffer, tow-friendlier carcass. The 285/70R17 is the upsize most owners land on: it fills the wheel wells properly and works as a mild 33, but on a stock-height truck it can rub depending on wheel offset — most owners run it with a lift or level, and some need minor trimming. The Limited's 245/60R20 is the odd one out; owners who want the A/T4W on a Limited usually step down to a 17-inch wheel-and-tire package, which is the better trail setup anyway.
6th Gen (2025+)
The 6th gen spreads across three wheel sizes. The SR5 starts on a 245/70R17, and the 265/70R17 A/T4W is the natural first step up. TRD Off-Road, TRD Pro, and Trailhunter trucks run a 265/70R18 from the factory, and Falken covers it with the LT265/70R18. Limited, Platinum, and TRD Sport trims sit on 20s — if you're shopping wheels to go with new tires, start with our 6th gen 4Runner wheels guide, which covers bolt pattern, sizes, and offset before you spend anything.
On-Road Manners
This is why the Wildpeak line owns so much of the 4Runner market: it behaves like a road tire most of the time. Owners consistently describe the A/T4W as one of the quieter all-terrains on the highway — the staggered shoulder blocks break up the tread pattern's noise instead of letting it drone — and the full-depth sipes give it wet-weather grip that doesn't fade as the tread wears down. The A/T4W's stiffer construction also fixed the A/T3W's soggiest trait: towing. With Heat Diffuser technology shedding sidewall heat under load, owners towing campers and boats report a noticeably more settled trailer than on the old tire.
The honest trade-offs: it's heavier than the tire it replaced, so expect a small fuel economy hit, especially if you jump to an LT size. And an E-load LT rides firmer than the SL version at the same size — fine if you tow or air down a lot, unnecessary if your 4Runner is mostly a commuter.
Off-Road and Weather
Every A/T4W size carries the three-peak mountain snowflake symbol, which means it met a real severe-snow traction standard — it's not just an M+S stamp. Because the sipes are full-depth, that winter bite is still there at half tread, which is where a lot of all-terrains quietly turn into hockey pucks. Owners in snow states run these year-round instead of swapping to dedicated winter tires, though a true winter tire still stops shorter on ice.
On dirt, the staggered shoulder blocks and scalloped tread edges bite in loose surfaces and help when aired down, and the DURASPEC 3-ply sidewalls on the LT285 sizes are the ones to pick if your trails are sharp rock — sidewall cuts, not tread wear, are what kill tires out there. Two builds from our own community run this tire: Josh Stewart's supercharged 5th gen and Jordan Van Calster's overland build both roll on Wildpeak A/T4Ws, which says plenty about how it holds up on trucks that actually get used.
Where it isn't the answer: deep mud. The tread packs up like every all-terrain does. If your weekends are mud bogs and rock gardens, that's mud-terrain territory — the A/T4W is built for the 90% of life that happens between trailheads.
Who Should Buy the A/T4W — and Who Should Skip It
Buy it if:
- Your 4Runner is a daily driver that also does trails, forest roads, and ski trips
- You're replacing A/T3Ws and want the same manners with better tread life and towing stability
- You tow and want the stiffer construction and Heat Diffuser technology
- You want one tire that handles real winter without a seasonal swap
Skip it if:
- Your trails are mostly mud or serious rock crawling — look at a mud-terrain instead
- You're chasing maximum fuel economy — the A/T4W is heavier than the A/T3W it replaces
- Your 4Runner never leaves pavement — a highway tire will ride quieter and last longer for less
FAQ
Is the A/T4W worth upgrading from the A/T3W?
For most 4Runner owners, yes. You get a longer treadwear warranty (65,000 miles for P-metric, 60,000 for LT), better towing stability, and tougher LT sidewalls, at the cost of a few pounds per tire. If your A/T3Ws still have plenty of tread, there's no rush — run them, and make the A/T4W your next set. Just don't mix the two on the same axle.
What size A/T4W fits a stock 4Runner?
Match your factory size and you're done: 265/70R17 for most 5th gens, LT265/70R18 for the 6th gen TRD Off-Road, TRD Pro, and Trailhunter, 265/65R18 for 18-inch 4th gens. The 285/70R17 upsize usually needs a lift or level and may need minor trimming depending on your wheel offset.
Is the A/T4W actually good in snow?
It's one of the better all-terrains in winter. Every size is three-peak mountain snowflake rated for severe snow, and the full-depth sipes keep biting as the tire wears. A dedicated winter tire is still the better tool for ice, but for most owners the A/T4W ends the seasonal tire swap.
How long does the A/T4W last?
Falken backs it with a 65,000-mile treadwear warranty on P-metric sizes and 60,000 miles on LT sizes, plus road hazard protection. Owners who rotate every 5,000–8,000 miles and keep the alignment honest generally see mileage in line with the warranty; heavy trail use wears any tire faster.
Should I get the SL or LT version?
The SL if your 4Runner is a daily that sees dirt roads and mild trails — it's lighter, softer-riding, and cheaper to feed fuel to. The LT if you tow, air down often, or run rocky trails where sidewall strength matters. The LT285/70R17 is the one that gets the DURASPEC 3-ply sidewall.
The Bottom Line
The Wildpeak A/T4W didn't try to reinvent the tire that half the 4Runner community already runs — it just fixed the complaints. Longer warranty, calmer towing, tougher LT sidewalls, same quiet road manners and real snow rating. If your 4Runner does a little of everything, this is the tire to beat.
