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
For example, 35×8.5-22 indicates ~35″ overall, 8.5″ wide, for a 22″ rim. Match the wheel number to your current wheel to avoid extra cost and fitment headaches.
Selecting by terrain balance
Choose if you prefer peak mud traction or steadier hard-pack manners. Going larger increases clearance 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
A 6-ply carcass provides stout sidewall support throughout the range. Yet bigger/heavier tires increase rotational mass, impacting acceleration and CVT feel.
Confirm steering clearance at full lock/compression, verify offsets if wheel diameter changes, and factor added payload (winch/cage) to keep suspension/gearing balanced.
- Decode size codes quickly to match your rim and avoid extra cost.
- Choose diameter for clearance; use width to tune cut-through vs float.
- Account for driveline and steering impacts prior to purchase.
| Variable | Impact | Action |
|---|---|---|
| Diameter | Clearance and approach angles | Go larger for deep mud and ruts |
| Tire width | Penetration vs flotation | Run narrower to cut to firm base |
| Weight | Rotational mass, acceleration | Check clutching/gearing accordingly |

Fast conclusions:
- Use the chart to compare real weights and loads so you can gauge acceleration feel and support for passengers and cargo.
- Uniform tread depth lets lugs dig in mud yet stay predictable on hard-pack.
- Jumping into the low-30s gains clearance without a huge weight penalty; the 42″ option adds mass but delivers serious load capacity.
- 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. EFX targets practical performance from muck to hard-pack.
Industry-first checkmark tread for traction in drive and reverse
The checkmark pattern interlocks lugs to create extra biting edges. It provides steady forward grip and dependable reverse traction for backing out.
Tall 2”+ lugs for superior mud grip
Staggered 2″+ lugs self-clean quickly and stabilize the patch in ruts. Reinforced shoulders and grooves boost lateral bite for planted side-hilling.
An ultra deep wheel lip protector shields bead lips and channels rocks and roots away from the bead area. This armoring custom wheels reduces cosmetic damage and helps maintain a sealed bead in punishing terrain.
| Feature | Purpose | Notes |
|---|---|---|
| Checkmark pattern | Two-way traction | Controlled recoveries and braking |
| Tall lugs | Mud evacuation and stability | Keeps momentum in deep sections |
| Deep wheel lip protector | Wheel protection | Helps avoid rim rash and burps |
Construction and compliance details
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.
It’s a tubeless lineup built specifically for UTVs. Tubeless fitment speeds installs, cuts rotating mass vs tubes, and enables quick plug repairs.
Compliance, loads, and handling notes
- Non-DOT: use off-road or on private land only, not public roads requiring DOT.
- Weights vary by SKU (~36–81 lb); most list 2.5″ tread depth and max loads ~740–1390 lb.
- Certain SKUs are oversized; plan special handling, storage, and shipping.
| Specification | Effect | Recommended action |
|---|---|---|
| 6-ply casing | Strength and stability under load | Verify load ratings vs GVWR |
| Tubeless build | Easier mounting; puncture repair options | Carry plugs + portable compressor |
| Non-DOT rating | Not for public road use | Keep usage off public roads |
Despite the aggressive look, the casing is tuned to deliver a more composed ride than many ag-style tire competitors. This engineered balance supports the ag-style performance claim—real structure beyond big lugs.
Verify load ratings/SKU notes to confirm support for passengers, cargo, and riding style. 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. 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. Correct alignment maximizes armoring custom wheels and prevents exposed spots.
With beadlocks, confirm ring/clamp shapes so the protector clears hardware on wide/concave faces.
Pairing with armoring custom wheels: debris control 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.
- Match rim/profile to balance mud grip and smooth trail manners.
- Wide stance builds may need fender extensions to control fling from aggressive lugs.
| Check | Why it Matters | Action |
|---|---|---|
| Width vs rim lips | Prevents pinching and protects finish | Compare inner/outer lip sizes |
| Beadlock hardware | Can interfere with protector coverage | Measure ring depth and clamp profile |
| Offset & backspace | Clearance for steering and brakes | Verify prior to purchase |
EFX’s thoughtful protector geometry rewards careful wheel selection. Result: fewer chips from custom wheels debris and cleaner rims after muddy weekends.
Performance by terrain: mud → hard-pack
Field reports show fierce mud bite with predictable handling on hard-pack.
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.
Checkmark geometry aids traction when pivoting or reversing. It cuts wheelspin and keeps control when stuck.
Smooth ride on graded trails and flats
On graded trails the carcass spreads load across the contact patch. Rider fatigue drops as chatter is reduced, keeping long days comfortable.
Going from wet sections to hard-pan remains predictable. The rig feels stable instead of twitchy, which helps you carry speed on connectors.
- Better flotation and rut-bridging than small knobbies, with modest steering effect.
- Riders report a balance of bite and poise that keeps groups moving as terrain changes.
- Designed for UTV use, many options keep a 2.5″ tread depth for consistent off-road performance.
| Terrain | Main benefit | Reason it matters |
|---|---|---|
| Deep 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 what ships now vs what has multi-week leads prevents last-minute stress.
Plenty of common fitments display “In Stock & Ready To Ship”. This leads to quicker delivery and fewer planning hiccups. A handful of larger options display a 4–6 week lead time—always check the selector to confirm ETA for your chosen configuration.
U.S. orders frequently qualify for free shipping, though some SKUs are marked as oversized items. Oversized listings often require special handling, and carriers may ask for a signature or specific delivery windows.
Quick shipping and delivery notes
- Plan ahead for lead-time SKUs if a trip is scheduled; order early to keep plans on track.
- Expect tracking updates from retailers once a set ships; oversized deliveries may need someone present to accept.
- Verify wheel specs pre-order so the ultra-deep lip protector and armoring custom wheels protect your rims immediately.
- These are tubeless and non-DOT—mount for off-road use only and keep plugs and a compressor handy for field repairs.
| Category | Typical Status | Buyer Action |
|---|---|---|
| Popular mid-range fitments | In stock & ready to ship | Order now; expect delivery in days |
| Large-diameter / oversized SKUs | Often 4–6 week lead time | Verify ETA; plan special delivery handling |
| U.S. shipping policy | Many SKUs ship free | Check cart for oversized fees before checkout |
| Notes | Tubeless, non-DOT | Use off-road only; prepare for field repairs |
