Maxxis's serious all terrain: the one for the ute or wagon that gets driven into rocks, rivers and a loaded tray. A three ply sidewall, a dual cord Armour Ply casing and wrap over shoulder armour, at the cost of noise and wet grip against a highway tyre.
- Built to resist damage first: 3 ply Debri-Shield sidewalls, Armour Ply casing, a nylon cap ply and a cut and chip resistant compound.
- 3D sipes that let the blocks work alone off road and lock together under braking.
- No comparison test exists for this pattern. In the United States it carries a 600 A B grade and a 60,000 mile treadwear warranty.
- No European label on our listing: the sizes we carry are not registered in Europe, and no treadwear grade either.
- Louder and slower to stop in the wet than a highway tyre, which is the price of the blocks. The quieter Razr is the AT-S.
- Ordered in from the New Zealand distributor, usually one business day. 1 size here, 17 inch.
What it is built to do
An all terrain for the four wheel drive that actually goes off road, built to take damage before it takes a puncture, with enough road manners to drive to the track.
Maxxis calls the AT811 the rugged adventurer, and the specification backs the name. The casing is a dual cord Armour Ply with intertwined reinforcing fibres, the sidewall is three ply with Debri-Shield blocks wrapping over the shoulder, and a high tensile nylon cap ply sits under the tread. The tread itself is big open blocks with 3D sipes and stepped chamfers on the block edges, and a two part shoulder block with a deep clearance groove. The compound is blended against cutting, tearing and chunking. Maxxis sells it in 64 sizes from 15 to 22 inch, many of them 10 ply light truck sizes; we list it in 225/65R17 106H.
How the tread and casing do their job
Maxxis names its features in its own words. Here is what each one is, how it works, what you notice, and what we can and cannot put a number on.
Armour Ply: the casing
A tyre's casing is the fabric skeleton under the rubber, and on most tyres each ply is a sheet of single cords. The AT811's casing ply is a dual cord: two reinforcing fibres twisted together in each cord, so the sheet is much harder to tear or push a stone through. It is the part of the tyre you never see and the part that decides whether a sharp rock on a river crossing is a scuff or a write off. You notice it as a tyre that holds its shape when aired down and shrugs off impacts that would bruise a road casing. There is no grade for it; the three ply sidewall it supports is the visible clue.
Debri-Shield: the three ply sidewall
The sidewall is the weak flank of every four wheel drive tyre, because it is thin, it flexes, and it is what a rock or a stump catches when the track narrows. The AT811 builds it three plies thick and then wraps the shoulder tread blocks over the top of it, so the first thing a rock meets is a block of tread rubber rather than the sidewall itself. You notice it when a track scrapes the side of the tyre and leaves a mark on a block instead of a cut in the sidewall. It is also why the tyre is heavier than a road tyre, and why it can be run at low pressure on sand without folding.
3D sipes and multi angled sipes
A sipe is a fine slit across a tread block, and every slit is an extra edge that bites. The AT811's sipes are cut in three dimensions, zigzagging down into the block rather than straight, and at several angles across it. Off road, with the tyre moulding itself over a rock or a rut, each part of the block can flex on its own and find its own grip. Under hard braking on the road the zigzag faces of the sipe push against each other and lock the block into one solid piece, so it does not squirm. You notice it as bite on a loose climb and a firm pedal on the seal, from the same tread.
Stepped chamfers on the block edges
A big square tread block slaps the road as it lands and drags as it leaves, which is the noise and the uneven wear an aggressive all terrain is known for. The AT811 cuts the leading edge of each block in steps, like a small staircase, so the block eases onto the road rather than hitting it flat and keeps more of its face on the ground under braking. You notice it as a tyre that is quieter around town than it looks, and that stops squarely instead of chattering. It is the road manner Maxxis added to the Razr; the AT-S goes further down that path if quiet is the priority.
Two part shoulder blocks with a clearance groove
The shoulder blocks are split in two with an extra deep groove between the halves, and each half is cut with its own edges. On a rutted track the split gives the tyre twice as many biting edges where the weight sits on a side slope, and the deep groove between them is a channel for mud and stones to clear out of instead of packing in. You notice it as a tyre that keeps gripping on a greasy sidling and cleans itself when you get back on the throttle. On the road, the same open shoulder is part of the noise, and we would rather say that than pretend it is silent.
A compound against cuts and chips, under a nylon cap
Gravel and rock do not wear an all terrain out so much as chip it: sharp stones tear pieces from the block edges until the tyre is ragged. The AT811's compound is blended with extra damage resistant fillers so the rubber tears less, and a high tensile nylon cap ply under the tread holds the whole tread band flat at speed and adds a layer for a stone to get through. You notice it as square block edges after a season on metal roads and a stable, round tyre at highway speed. Our listing carries no treadwear grade, so the only number we have is the United States one: 600, on the 265/70R17.
Read the label for your size, not for the pattern
The European label is measured size by size, and many AT811 sizes are not sold in Europe, so they carry none. These are the grades on our listings on 22 September 2026.
| Size | Load and speed | Fuel | Wet grip | Noise |
|---|---|---|---|---|
| 225/65R17 | 106H | no European label | no European label | no European label |
Where the Razr AT811 fits and where it does not
Good for
- Four wheel drives on 17 inch wheels that go off road on purpose: tracks, rivers, rocks, the beach
- Utes that tow and carry, in the 10 ply light truck sizes
- Drivers who want the aggressive look with a casing to match
Better served by another tyre
- Commute all week, gravel at the weekend: the Maxxis Razr AT-S, the quiet Razr
- Deep mud every weekend: the Maxxis Razr MT772 or Bighorn MT764
- Never leaves the seal: the Maxxis Bravo HP-M3
- The house brand price: our Anchee AC858, 14 sizes from 15 to 20 inch
