The short answer

The mud terrain New Zealand four wheel drivers know by name. The best off road score of any Maxxis we sell, a reinforced casing built to take punishment, and the noise on the highway that every Bighorn owner already knows about.

  • 31 Australian owners rate it 82 percent: off road 96, value 88, dry 86, noise 63.
  • Built to take punishment: reinforced casing, extra nylon cap ply, G shaped buttresses with stone ejectors on the sidewall.
  • The Eagle Claw tread: staggered, multi edged blocks that self clean and keep biting as they wear.
  • Loud on the highway. The one thing owners criticise, and the Razr MT772 is the quieter mud terrain if that matters.
  • No European label and no treadwear grade on our listing, and no comparison test.
  • Ordered in from the New Zealand distributor, usually one business day. 1 size here, 15 inch.

What it is built to do

A mud terrain for the four wheel drive that goes where a standard 4x4 tyre stops: deep mud, wet clay, rutted tracks and rock, with the casing to survive it.

Maxxis calls the Bighorn its proven mud grip legend, and the name has been on Kiwi utes and wagons long enough to earn it. The tread is the Eagle Claw, a multi edged, staggered block design cut in two stages so the tyre bites and self cleans in mud and keeps doing it as the blocks wear down. Under it is a reinforced casing with an extra nylon cap ply, and down the sidewall run G shaped buttress reinforcements with stone ejectors to keep sharp objects out of the flank. Maxxis lists it in 19 sizes from 14 to 18 inch, 6 to 10 ply; we list 235/75R15 104Q 6 ply.

How the tread and casing do their job

Maxxis names four features. Here is what each one is, how it works, what you notice, and what we can and cannot put a number on.

The Eagle Claw tread

A mud terrain grips by digging, and every edge on a block is a claw. The Bighorn's blocks are cut with many edges rather than four flat sides, and staggered across the tread so no two rows land in line, which means there is always an edge biting in whichever direction the tyre is being pushed, forward on a climb, sideways on a greasy sidling, backwards when you reverse out. The wide voids between the blocks let the mud that packs in fall out again as the tyre rolls, so the claws are clean for the next turn. Owners score off road at 96 percent, and self cleaning is what they praise. The same voids are the highway noise.

The dual stage tread

Each block is moulded in two levels, a full height face and a lower step beside it. In soft ground the upper edge bites first and the lower step bites as the block sinks, so the tyre keeps pulling when a plain block would already be buried. The step also lets the block flex over a rock instead of standing rigid, and it removes rubber the tyre does not need, which is why Maxxis says it cuts weight and sharpens the steering. As the tread wears down the lower step becomes the working edge, so the tyre keeps biting late in its life. You notice it as a mud terrain that still works at half tread, and as the blocks that give the Bighorn its look.

The reinforced casing and extra nylon cap ply

A tyre's casing is the fabric skeleton under the rubber, and on a mud terrain it is what decides whether a sharp rock is a scuff or a puncture. The Bighorn's casing is reinforced, and an extra nylon cap ply is wound around it under the tread: a layer that holds the tread band flat and round at highway speed and adds a barrier for a stone to get through. Owners write about sets past 30,000 km with no punctures and about running them loaded all week, which is what that layer buys. The ply rating on the sidewall is the strength grade of the whole casing, 6, 8 or 10 depending on the size, and a higher grade rides harder when the vehicle is empty.

G shaped buttresses with stone ejectors

The sidewall is the weak flank of a 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 Bighorn moulds a row of G shaped rubber buttresses around the upper sidewall, so a rock meets a thick block of rubber before it meets the flank, and the buttresses are shaped to lever out a stone that lodges between them before it can drill in. You notice it when a track scrapes the side of the tyre and leaves a mark on a buttress instead of a cut in the sidewall, and on a rutted track as extra grip when the tyre is sunk to its shoulders. There is no grade for it; the owners' puncture record is the evidence.

The sizes we list

A mud terrain's speed letter is lower than a road tyre's, and the ply rating matters as much as the load index on a vehicle that tows. The European label is measured size by size, and mud terrain sizes are rarely sold in Europe, so most carry none. Read on 23 September 2026.

Where the Bighorn MT764 fits and where it does not

Good for

  • Four wheel drives on 15 inch wheels that go into mud, clay and rock on purpose
  • Farm, forestry and hunting access, where a puncture is a long walk
  • Drivers who want the proven mud terrain at a price below the newer Razr

Better served by another tyre

Is it the right tyre

Is the Maxxis Bighorn MT764 actually any good?

Yes, and it has the record to show it. Thirty one Australian owners rate it 82 percent, with off road at 96, the highest off road score of any Maxxis pattern we sell, dry at 86, value at 88 and noise the lowest at 63. The written reviews are about durability: sets past 30,000 km with no punctures, and professional users who run it loaded all week, and three more owners on Tyre Reviews average 87 percent. No magazine has put it in a comparison test, and our listing carries no label or grade. The Bighorn earned its name in mud, and it is still the loud one on the road, which we would rather say than hide.

What is it not good at?

Noise, and it does not pretend otherwise. Owners score noise at 63 percent, well below every other mark they give it, and the most common written criticism is that it is loud on the highway. A mud terrain also gives up wet braking on seal to an all terrain, because there is less rubber on the road, and our listing carries no European label, so there is no wet grip grade to quote. If the vehicle does more seal than mud, the Razr AT811 is the tyre; if you want a mud terrain that is quieter on the way there, the Razr MT772.

Bighorn MT764 or Razr MT772?

The Bighorn is the proven one and the Razr the newer one. The MT764 has been on New Zealand four wheel drives for a generation, with 31 Australian owners at 82 percent and the highest off road score in our Maxxis range; it costs less, and it is the louder of the two. The MT772 brings the Armour Ply casing, the three ply sidewall, the ejector bars and a tread arranged for quiet, with 97 owners at 87 percent and a 10,000 km magazine test behind it. Mud first and price, the Bighorn. Mud with a lot of highway in between, the MT772.

Which lettering will I get?

It depends on the size. The distributor lists most Bighorn sizes with raised white letters, some with outline white letters and the 195R14C with a plain black sidewall. The tread and the casing are the same whichever you get, and a white letter tyre can be fitted letters in if you prefer black. Say which you want when you order and we will tell you what your size comes as.
Ratings and sizes

How long will it last?

There is no treadwear grade on our listing and no wear test on this pattern, so we do not quote a figure. The 31 Australian owners score wear at 79 percent, and the written reviews include sets past 30,000 km still going, which for a mud terrain is a good report. The dual stage tread is designed so the tyre keeps biting as it wears down, and the harder compound is chosen for chip resistance over grip on seal. Rotate it: it is symmetric and not directional, so it can move to any corner.

What do the ply ratings mean?

A strength grade for the casing, not a count of layers: 6 ply on the 15 inch flotation sizes, 8 ply on most 16 and 17 inch sizes and 10 ply on the heavy 16 inch light truck sizes. A higher grade holds a heavier load at a higher pressure and resists a stone through the tread, and rides harder when the vehicle is empty. Match or beat the load index on your door placard, and take the 10 ply where you tow. Our load rating guide explains the numbers.

Why is there no European label?

Because the sizes we list are not sold in Europe, so they are never labelled. It says nothing about the tyre. Where a size of ours does carry a label, the grade sits against that size on its own page, never against the pattern name.

Which way round does it go on?

Any way. The tread is symmetric and not directional, so a tyre can go on any corner of the vehicle and can be rotated front to back or crossed side to side, which on a mud terrain is the single biggest thing you can do for its life and its noise. Our tread pattern guide shows the three types.
Buying

Bighorn MT764 or Anchee Grandtrac MT1?

Price against the record. The Grandtrac is our own mud terrain, 11 sizes from 15 to 17 inch, and it costs less. The Bighorn has a generation of New Zealand four wheel drives, 31 Australian owners at 82 percent and a 96 percent off road score behind it; the Grandtrac has none of that record, because nobody tests a brand only sold in New Zealand. The Grandtrac for the price, the Bighorn for the name.

How long does it take to get one?

Usually one business day for anything listed on this page, because Maxxis is ordered in from the New Zealand distributor rather than held on our shelves. Maxxis New Zealand lists 19 sizes from 14 to 18 inch, from 195R14C to 305/70R16 and the 27 to 33 inch flotation sizes, so if yours is not here, ask.

Can you fit them for me?

Yes. Every size has a fitted and balanced option at our Te Puke workshop. Choose it on the tyre's own page, then book a time online.
