How to choose your MotoHavok tire size today
Select accurately by decoding sidewall sizes and matching them to wheel specs and ride priorities.
Decode sizing & match to wheel diameter
Sizes like 35×8.5-22 mean about 35″ overall diameter, 8.5″ section width, and a 22″ wheel. Keep the wheel diameter the same as your current rim to avoid added costs and fitment issues.
Selecting by terrain balance
Decide whether you want maximum deep mud traction or a more composed hard-pack ride. 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.
Mind clearance, gearing, and weight
A 6-ply carcass provides stout sidewall support throughout the range. But taller, heavier options add rotational mass and can change acceleration and CVT behavior.
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 sizes fast to match your wheel and save money.
- Pick diameter for clearance; choose width for how the tread digs into mud.
- Plan ahead for steering/driveline effects.
| Item | Effect | What to do |
|---|---|---|
| Diameter | Ground clearance, approach angle | Choose larger for deep mud runs |
| Tire width | Penetration vs flotation | Run narrower to cut to firm base |
| Weight | Rotational load and acceleration | Check clutching/gearing accordingly |

Key takeaways:
- Leverage the chart to weigh acceleration feel vs passenger/cargo support.
- The consistent tread depth helps the lugs claw through slop while keeping predictable contact on hard-pack.
- Low-30″ sizes gain clearance with modest weight; 42″ adds mass but significant load capacity.

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.
2”+ lugs for standout deep-mud bite
With 2″+ staggered lugs, mud sheds quickly and the patch stays stable in ruts. Reinforced grooves and shoulder blocks add lateral grip so side-hilling feels planted, not sketchy.
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 geometry | Two-way traction | Controlled recoveries and braking |
| 2″+ lugs | Mud evacuation and stability | Keeps momentum in deep sections |
| Deep wheel lip protector | Wheel protection | Reduces rim damage and burping |
Build and compliance notes
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. This gives sidewall stiffness for stability while allowing enough flex to conform to ruts and obstacles.
It’s a tubeless lineup built specifically for UTVs. Going tubeless simplifies mounting, reduces rotating mass, and supports fast plug-type fixes.
Load and handling considerations
- These are non-DOT; off-road/private property only—avoid public roads needing 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.
| Spec | Impact | Action |
|---|---|---|
| 6-ply casing | Strength and stability under load | Verify load ratings vs GVWR |
| Tubeless construction | Simpler installs; quick plug repairs | Carry plugs + portable compressor |
| Non-DOT | Not for public road use | Keep usage off public roads |
Even with an aggressive profile, the casing aims for a more composed ride vs many ag-style options. 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. Doing so prevents surprises at delivery and maintains predictable performance.
Fitment tips for wheels and custom setups
Get rim/profile fit right to protect finishes and refine handling.
Pick a section width that matches rim lips. An 8.5″ section usually sits well on deep rims—no pinch or balloon.
Verify bead and flange alignment to let the ultra deep wheel lip protector cover the rim edge. 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.
Pairing with armoring custom wheels: debris control in motion
Mind offset/backspacing so the protector clears tie rods/knuckles yet still shields the bead. Dry-fit one corner to confirm caliper clearance at full lock.
- Run hub-centric rings and quality lugs for concentric fit and less vibration.
- Balance mud traction smooth feel by matching the rim and profile for both swamp runs and trail cruising.
- Wide-stance setups may require fender extensions to limit lug fling.
| Check | Reason | Quick Action |
|---|---|---|
| Section width vs rim lip | Avoids pinching and protects finish | Match inner/outer lip measurements |
| Beadlock ring/hardware | May interfere with protector | Check ring depth and clamp geometry |
| Offset/backspacing | Clearance for steering and brakes | Verify prior to purchase |
EFX’s protector geometry pays off when wheels are chosen carefully. 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
In clay/gumbo, tall lugs and wide voids self-clean effectively. It sustains deep-mud bite through long, heavy-throttle sections.
Checkmark geometry aids traction when pivoting or reversing. This reduces spin and helps you maintain control in sticky situations.
Composed hard-pack ride on trails and flats
On graded routes, the carcass spreads load over the 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. The rig feels stable instead of twitchy, which helps you carry speed on connectors.
- 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.
| Surface | Primary Benefit | Why it Matters |
|---|---|---|
| Mud | Self-clearing lugs | Keeps traction through long pulls |
| Hard-pack | On-center stability | Cuts fatigue; sustains speed |
| Mixed terrain | Predictable transitions | Maintains momentum without twitch |
Buy confidently: inventory, lead times & U.S. shipping
Knowing which items ship now versus those with multi-week lead times saves last-minute headaches.
A lot of popular sizes list “In Stock & Ready To Ship” on retailer pages. That means faster delivery and fewer scheduling surprises. 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. 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.
- Expect tracking updates from retailers once a set ships; oversized deliveries may need someone present to accept.
- Verify wheel specs before ordering so the feature ultra deep lip protector and armoring custom wheels benefit your rims right away.
- Non-DOT tubeless—off-road use; keep a plug kit and compressor ready.
| Category | Common status | Buyer Action |
|---|---|---|
| Popular mid-range fitments | In stock & ready to ship | Order now; expect delivery in days |
| Large-diameter / oversized listings | Commonly 4–6 week lead time | Confirm ETA; plan for special delivery handling |
| U.S. shipping | Free shipping on many SKUs | Review cart for oversized surcharges |
| Product notes | Tubeless, non-DOT | Use off-road only; prepare for field repairs |
