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
Sizes like 35×8.5-22 mean about 35″ overall diameter, 8.5″ section width, and a 22″ wheel. Match the wheel number to your current wheel to avoid extra cost and fitment headaches.
Choose 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, and weight considerations for your UTV
A 6-ply carcass provides stout sidewall support throughout the range. However, taller/heavier sizes add rotating mass and can affect acceleration and CVT response.
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.
- Choose diameter for clearance; use width to tune cut-through vs float.
- Plan for driveline and steering changes before upgrading.
| Item | Effect | What to do |
|---|---|---|
| Overall diameter | Clearance and approach angles | Go larger for deep mud and ruts |
| Tire width | Cut-through vs float | Use narrower to punch through mud |
| Weight | Rotational mass, acceleration | Verify clutching and gearing |

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.
- Low-30″ sizes gain clearance with modest weight; 42″ adds mass but significant load capacity.
- Check availability and free shipping notes—many are in stock, some list 4–6 week lead times.
Grip engineering: pattern, lugs, and rim protection
Here the design focuses on grip—each tread element and protector is purposeful. EFX targets practical performance from muck to hard-pack.
Checkmark tread: traction in both directions
Checkmark geometry interlocks blocks for added biting edges. This yields predictable bite going forward and reliable reverse traction for extraction.
Enormous 2”+ lugs for unparalleled deep mud performance
Tall, staggered 2″+ lugs clear mud fast and keep the contact patch stable across 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 protection for custom wheels trims cosmetic rash and helps maintain bead seal off-road.
| Design | Purpose | Notes |
|---|---|---|
| Checkmark geometry | Two-way 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 |
Construction and compliance details
Construction decisions shape mud-tire behavior under real UTV stresses.
The core engineering is a bulletproof 6-ply carcass built on a bias belt platform. 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.
Load and handling considerations
- 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.
- Some SKUs are oversized items—plan for special handling, storage, and shipping on larger orders.
| Spec | Effect | Action |
|---|---|---|
| 6-ply casing | Strength and stability under load | Match load ratings to your GVWR |
| Tubeless construction | Easier mounting; puncture repair options | Keep plugs and a compressor on board |
| Non-DOT rating | Off-road use only | 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.
Review load ratings and SKU notes to ensure passenger/gear support matches your riding. This reduces surprises at delivery and keeps performance predictable.
Wheel fitment guidance for custom builds
A proper match between rim and profile protects finishes and improves handling.
Choose a section width that aligns with your wheel lips. Common 8.5 options work well on many deep wheel rims without pinching or ballooning.
Verify bead and flange alignment to let the ultra deep wheel lip protector cover the rim edge. Correct alignment maximizes armoring custom wheels and prevents exposed spots.
For beadlocks, double-check ring thickness and clamp geometry so the protector clears hardware on concave or wide faces.
Pairing with armoring custom wheels: debris control in motion
Consider offset and backspacing so the protector clears tie rods and knuckles while still shielding the bead. Test-fit a corner to verify full-lock caliper clearance.
- Run hub-centric rings and quality lugs for concentric fit and less vibration.
- 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.
| Fitment Check | Why it Matters | Action |
|---|---|---|
| Section width vs rim lip | Avoids pinching and protects finish | Match inner/outer lip measurements |
| Beadlock hardware | May interfere with protector | Measure ring depth and clamp profile |
| Offset/backspacing | Steering/brake clearance | Verify prior to purchase |
Thoughtful protector geometry from EFX benefits smart wheel choices. Result: fewer chips from custom wheels debris and cleaner rims after muddy weekends.
From mud to hard-pack: performance overview
Field reports show fierce mud bite with predictable handling on hard-pack.
Unparalleled deep mud traction without sacrificing stability
Tall lugs and wide voids self-clear in clay pits and gumbo. That keeps deep mud traction during long, throttle-heavy pulls.
The checkmark layout supports traction moves for pivots or backing out. That limits spin and helps maintain control in sticky spots.
Smooth ride on graded trails and flats
On graded trails the carcass spreads load across the contact patch. Hands and shoulders feel less chatter, so long days stay comfortable.
When you hop from puddles to hard-pan, the contact patch transitions predictably. Stability beats twitchiness, helping carry speed on connectors.
- Flotation/rut bridging beat small knobbies with minimal steering penalty.
- 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.
| Terrain | Primary Benefit | Reason it matters |
|---|---|---|
| Mud | Self-clearing lugs | Keeps traction through long pulls |
| Hard-pack | On-center stability | Cuts fatigue; sustains speed |
| Mixed runs | Predictable transitions | Maintains momentum without twitch |
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. Select big-diameter SKUs note 4–6 week leads—verify ETA in the selector.
U.S. orders frequently qualify for free shipping, though some SKUs are marked as oversized items. Oversized items may need special handling; carriers can require signatures or scheduled windows.
Fast shipping notes
- If a trip is coming, plan for lead-time items and order early.
- You’ll get tracking once shipped; oversized items may need in-person acceptance.
- 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.
