EFX MotoHavok: Shop the ag-style mud tire built for UTVs

What sets this ag-style mud tire apart in a crowded market?

You get aggressive bite alongside predictable handling. The industry-first checkmark tread delivers traction in drive and reverse, keeping recoveries controlled.

The stout 6-ply bias carcass works with 2″+ lugs to keep mud bite strong while maintaining hard-pack composure. An ultra-deep wheel-lip protector shields custom wheels from rocks/roots on the move.

Quick specs at a glance

• Build: 6-ply bias carcass; tubeless; UTV use only.
• Tread: many sizes at 2.5″ depth; pattern engineered for forward/reverse traction.
• Protection: deep wheel-lip protector to help deflect debris and protect rims.

MotoHavok tire size — choosing the right fit now

Select accurately by decoding sidewall sizes and matching them to wheel specs and ride priorities.

Decode sizing & match to wheel diameter

For example, 35×8.5-22 indicates ~35″ overall, 8.5″ wide, for a 22″ rim. Keep the wheel diameter the same as your current rim to avoid added costs and fitment issues.

Pick based on terrain needs

Choose if you prefer peak mud traction or steadier hard-pack manners. Going larger increases clearance for ruts and bogs.

Narrower sections, such as 8.5″, help the profile cut through mud to firmer layers, while wider choices spread contact for stability on flats.

Mind clearance, gearing, and weight

The standard 6-ply carcass supplies strong sidewall support across sizes. However, taller/heavier sizes add rotating mass and can affect acceleration and CVT response.

Verify clearance at full lock and bump, confirm offset with new rim diameters, and include payload (winches/cages) so suspension and gearing remain balanced.

• Decode size codes quickly to match your rim and avoid extra cost.
• Pick diameter for clearance; choose width for how the tread digs into mud.
• Plan ahead for steering/driveline effects.

Quick takeaways:

• Compare true weights/loads to predict acceleration feel and payload support.
• The consistent tread depth helps the lugs claw through slop while keeping predictable contact on hard-pack.
• Moving to low-30s boosts clearance with minor mass increase; 42″ ups mass and payload.
• Confirm stock status—numerous sizes ship now; others show 4–6 week waits.

Grip engineering: pattern, lugs, and rim protection

This engineering prioritizes grip; every tread block, lug, and protector has a job. The EFX design focuses on real-world performance from mud to hard-pack.

First-of-its-kind checkmark tread: traction forward & reverse

The checkmark pattern interlocks lugs to create extra biting edges. This yields predictable bite going forward and reliable reverse traction for extraction.

Tall 2”+ lugs for superior mud grip

Tall, staggered 2″+ lugs clear mud fast and keep the contact patch stable across ruts. Reinforced grooves/shoulders add lateral hold so side-hilling feels planted.

The ultra-deep lip protector shields bead lips, channeling rocks/roots away. This armoring custom wheels reduces cosmetic damage and helps maintain a sealed bead in punishing terrain.

Construction and compliance details

Construction choices drive how a mud-focused wheel performs under real UTV loads.

The core engineering is a bulletproof 6-ply carcass built on a bias belt platform. That balance yields sidewall stiffness for stability yet enough flex to conform to ruts/obstacles.

All sizes are tubeless and tuned for UTV duty. Tubeless mounting eases installation, lowers rotating mass versus tubes, and lets you manage punctures quickly with plugs.

Compliance, loads, and handling notes

• These are non-DOT; off-road/private property only—avoid public roads needing DOT.
• Expect ~36–81 lb weight range, common 2.5″ depth, and max loads near 740–1390 lb.
• Oversized SKUs may need special handling, storage, and shipping arrangements.

Despite the aggressive look, the casing is tuned to deliver a more composed ride than many ag-style tire competitors. Engineering—not just big lugs—underpins the ag-style performance balance.

Check load ratings and SKU notes before ordering so your choice supports passengers, gear, and the way you ride. This reduces surprises at delivery and keeps performance predictable.

Fitment guidance for wheels and custom builds

A proper match between rim and profile protects finishes and improves handling.

Pick a section width that matches rim lips. Common 8.5 options work well on many deep wheel rims without pinching or ballooning.

Confirm bead/flange alignment so the ultra-deep lip protector overlays the rim edge. Correct alignment maximizes armoring custom wheels and prevents exposed spots.

On beadlocks, verify ring thickness and clamp geometry to clear the protector around hardware.

Pairing with armoring custom wheels to manage debris in motion

Mind offset/backspacing so the protector clears tie rods/knuckles yet still shields the bead. Test-fit a corner to verify full-lock caliper clearance.

• Hub-centric rings + quality lugs help keep things concentric and smooth.
• Balance mud bite with smooth feel by pairing rim/profile for swamps and trails.
• Wide-stance setups may require fender extensions to limit lug fling.

Thoughtful protector geometry from EFX benefits smart wheel choices. Outcome: reduced custom wheel rash and cleaner rims after mud runs.

From mud to hard-pack: performance overview

Real-world runs show the pack delivers both fierce grip in muck and predictable manners on firm ground.

Deep mud traction without losing stability

In clay/gumbo, tall lugs and wide voids self-clean effectively. This preserves deep-mud traction during long, throttle-heavy pulls.

Checkmark geometry aids traction when pivoting or reversing. It cuts wheelspin and keeps control when stuck.

Smooth ride on graded trails and flats

The carcass distributes load evenly on graded trails. With less chatter, long days feel more comfortable.

Going from wet sections to hard-pan remains predictable. Stability beats twitchiness, helping carry speed on connectors.

• Flotation and rut bridging improve over small knobbies without big steering penalties.
• Feedback notes bite + poise that maintains momentum as terrain varies.
• Designed for UTV use, many options keep a 2.5″ tread depth for consistent off-road performance.

Inventory, lead times, and U.S. shipping: buy with confidence

Knowing what ships now vs what has multi-week leads prevents last-minute stress.

Many popular fitments show “In Stock & Ready To Ship” on retail pages. That means faster delivery and fewer scheduling surprises. Some larger sizes show 4–6 week leads—check the selector for ETA on your exact configuration.

U.S. orders frequently qualify for free shipping, though some SKUs are marked as oversized items. Expect special handling on oversized SKUs; couriers may require signatures/windows.

Fast shipping notes

• If a trip is coming, plan for lead-time items and order early.
• Retailers send tracking after shipment; oversized deliveries can require someone present.
• Double-check wheel specs so the deep lip protector and armoring custom wheels work as intended.
• These are tubeless and non-DOT—mount for off-road use only and keep plugs and a compressor handy for field repairs.

Wrapping It Up

Wrap up your decision by matching real-world needs to published specs and fitment notes.

You get 2″+ lugs and a 6-ply bias carcass for deep-mud grip, with calm hard-pack behavior. The ultra-deep wheel-lip protector adds real rim armor for custom builds.

Let weights, load ratings, and 2.5″ depth guide your diameter/width choice for clearance and load. Double-check clutching and gearing after larger upgrades.

Plenty of popular sizes are in stock; some list 4–6 week leads. Confirm availability, place the order, and get back out riding.
