MotoHavok tire size — choosing the right fit now
Select accurately by decoding sidewall sizes and matching them to wheel specs and ride priorities.
Reading sizes and matching to wheel diameter
A size such as 35×8.5-22 equals ~35″ OD, 8.5″ width, on a 22″ wheel. Match that final number to your rim to prevent extra expense and fitment problems.
Selecting by terrain balance
Decide between maximum mud bite or a calmer hard-pack feel. Larger diameters lift the chassis for ruts and bogs.
An 8.5″ section can cut through to firm base, whereas wider sections add stability on level ground.
Clearance, gearing & weight: key considerations
The standard 6-ply carcass supplies strong sidewall support across sizes. Yet bigger/heavier tires increase rotational mass, impacting acceleration and CVT feel.
Check steering clearance at full lock and compression, verify offsets when changing wheel diameter, and account for added payload from winches or cages so suspension and gearing stay in balance.
- 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.
| Item | Effect | What to do |
|---|---|---|
| Overall diameter | Clearance and approach angles | Choose larger for deep mud runs |
| Section width | Cut-through vs float | Use narrower to punch through mud |
| Weight | Rotational mass, acceleration | Verify clutching and gearing |

| 42×8.5-24 | 61.8 | 1390 | 2.5″ |
Fast conclusions:
- Compare true weights/loads to predict acceleration feel and payload support.
- Uniform tread depth lets lugs dig in mud yet stay predictable on hard-pack.
- Moving to low-30s boosts clearance with minor mass increase; 42″ ups mass and payload.
- Verify stock and shipping—many sizes are in; some carry 4–6 week leads.
Grip engineering: pattern, lugs, and rim protection
This engineering prioritizes grip; every tread block, lug, and protector has a job. EFX targets practical performance from muck to hard-pack.
Checkmark tread: traction in both directions
Checkmark geometry interlocks blocks for added biting edges. It provides steady forward grip and dependable reverse traction for backing out.
Enormous 2”+ lugs for unparalleled deep mud performance
Staggered 2″+ lugs self-clean quickly and stabilize the patch in ruts. Reinforced grooves/shoulders add lateral hold so side-hilling feels planted.
A deep wheel-lip protector guards bead lips and deflects debris from the bead. This armoring custom wheels reduces cosmetic damage and helps maintain a sealed bead in punishing terrain.
| Feature | Purpose | Why it helps |
|---|---|---|
| Checkmark pattern | Forward and reverse traction | Controlled recoveries and braking |
| 2″+ lugs | Mud evacuation and stability | Keeps momentum in deep sections |
| Lip protector | Rim defense | Helps avoid rim rash and burps |
Build and compliance notes
Construction choices drive how a mud-focused wheel performs under real UTV loads.
It uses a stout 6-ply bias-belt carcass at the core. You get sidewall stiffness for stability plus flex to contour over ruts and 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
- Non-DOT: use off-road or on private land only, not public roads requiring DOT.
- Published weights range across SKUs (roughly 36–81 lbs) and most have a 2.5″ tread depth and max loads from about 740 to 1390 lbs.
- Certain SKUs are oversized; plan special handling, storage, and shipping.
| Specification | Impact | Recommended action |
|---|---|---|
| 6-ply casing | Load stability and strength | Verify load ratings vs GVWR |
| Tubeless build | Simpler installs; quick plug repairs | Keep plugs and a compressor on board |
| Non-DOT | Not for public road use | Limit use to trails and private land |
Despite the aggressive look, the casing is tuned to deliver a more composed ride than many ag-style tire competitors. That engineered balance is what makes the ag-style tire easy claim more credible—real structure, not just big lugs.
Check load ratings and SKU notes before ordering so your choice supports passengers, gear, and the way you ride. That helps avoid delivery surprises and preserves predictable results.
Fitment guidance for wheels and custom builds
Matching rim and profile correctly protects finishes and sharpens handling.
Select a section width that suits your rim lips. The common 8.5″ option fits deep rims well without pinching/ballooning.
Check bead/flange alignment so the deep lip protector fully covers the rim. Good alignment optimizes protection for custom wheels and avoids exposed lips.
With beadlocks, confirm ring/clamp shapes so the protector clears hardware on wide/concave faces.
How to pair with armoring custom wheels for debris management
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 builds may need fender extensions to control fling from aggressive lugs.
| Check | Reason | Quick Action |
|---|---|---|
| Section width vs rim lip | Prevents pinching and protects finish | Match inner/outer lip measurements |
| Beadlock ring/hardware | Can interfere with protector coverage | Measure ring depth and clamp profile |
| Offset/backspacing | Steering/brake clearance | Verify prior to purchase |
EFX’s protector geometry pays off when wheels are chosen carefully. 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.
Serious mud grip with consistent stability
Tall lugs and wide voids self-clear in clay pits and gumbo. It sustains deep-mud bite through long, heavy-throttle sections.
The checkmark tread supports traction drive moves when you need to pivot or back out. That limits spin and helps maintain control in sticky spots.
Smooth hard-pack ride quality for trails and flats
On graded trails the carcass spreads load across the contact patch. With less chatter, long days feel more comfortable.
Going from wet sections to hard-pan remains predictable. You get stability—not twitch—so connectors can be taken with confidence.
- Flotation and rut bridging improve over small knobbies without big steering penalties.
- Riders report a balance of bite and poise that keeps groups moving as terrain changes.
- UTV-specific; numerous options maintain 2.5″ depth for steady off-road behavior.
| Terrain | Main benefit | Why it Matters |
|---|---|---|
| Mud | Self-clearing lugs | Keeps traction through long pulls |
| Hard-pack | On-center stability | Reduces rider fatigue; keeps speed |
| Mixed terrain | Predictable transitions | Keeps momentum without twitchiness |
Buy confidently: inventory, lead times & U.S. shipping
Knowing which items ship now versus those with multi-week lead times saves last-minute headaches.
Plenty of common fitments display “In Stock & Ready To Ship”. That yields faster delivery with fewer scheduling surprises. Some larger sizes show 4–6 week leads—check the selector for ETA on your exact configuration.
U.S. shipments often ship free; certain SKUs are oversized. Oversized items may need special handling; carriers can require signatures or scheduled windows.
Fast shipping notes
- Plan ahead for lead-time SKUs if you’re timing a trip; order earlier to ensure your matter terrain plans stay on track.
- You’ll get tracking once shipped; oversized items may need in-person acceptance.
- Verify wheel specs pre-order so the ultra-deep lip protector and armoring custom wheels protect your rims immediately.
- Tubeless and non-DOT—off-road only; carry plugs and a compressor for field fixes.
| Category | Typical Status | Buyer Action |
