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.
Choose 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.
Narrower sections (e.g., 8.5″) slice down to firmer layers; wider choices spread contact for stability on flats.
Clearance, gearing, and weight considerations for your UTV
The common 6-ply carcass construction gives strong sidewall support across the lineup. 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 sizes fast to match your wheel and save money.
- Select diameter to gain clearance and width to control cut-through/float.
- Plan for driveline and steering changes before upgrading.
| Item | Effect | Action |
|---|---|---|
| Overall diameter | Ground clearance, approach angle | Choose larger for deep mud runs |
| Section width | Cut-through vs float | Use narrower to punch through mud |
| Weight | Rotational load and acceleration | Verify clutching and gearing |

| 42×8.5-24 | 61.8 | 1390 | 2.5″ |
Quick 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.
- Verify stock and shipping—many sizes are in; some carry 4–6 week leads.
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.
First-of-its-kind checkmark tread: traction forward & reverse
A checkmark layout interlocks lugs to increase edges. This yields predictable bite going forward and reliable reverse traction for extraction.
2”+ lugs for standout deep-mud bite
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. That armoring custom wheels limits cosmetic damage and helps keep the bead sealed in harsh terrain.
| Feature | Purpose | Why it helps |
|---|---|---|
| Checkmark pattern | Two-way traction | Predictable extraction and braking |
| Tall lugs | Self-cleaning with stability | Keeps momentum in deep sections |
| Deep wheel lip protector | Rim defense | Helps avoid rim rash and burps |
Construction & 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.
It’s a tubeless lineup built specifically for UTVs. Tubeless fitment speeds installs, cuts rotating mass vs tubes, and enables quick plug repairs.
Load and handling considerations
- These are non-DOT; off-road/private property only—avoid public roads needing 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 | Effect | Recommended action |
|---|---|---|
| 6-ply casing | Load stability and strength | Match load ratings to your GVWR |
| Tubeless build | Simpler installs; quick plug repairs | Carry plugs + portable compressor |
| Non-DOT | Off-road use only | Limit use to trails and private land |
Although aggressive in appearance, the casing is tuned for calmer ride quality than many ag-style rivals. That engineered balance is what makes the ag-style tire easy claim more credible—real structure, not just big lugs.
Review load ratings and SKU notes to ensure passenger/gear support matches your riding. That helps avoid delivery surprises and preserves predictable results.
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. The common 8.5″ option fits deep rims well without pinching/ballooning.
Confirm bead/flange alignment so the ultra-deep lip protector overlays the rim edge. Good alignment optimizes protection for custom wheels and avoids exposed lips.
On beadlocks, verify ring thickness and clamp geometry to clear the protector around hardware.
Pairing with armoring custom wheels to manage debris in motion
Consider offset and backspacing so the protector clears tie rods and knuckles while still shielding the bead. Dry-fit a corner to confirm caliper clearance at full lock.
- 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 | Match inner/outer lip measurements |
| Beadlock ring/hardware | May interfere with protector | Measure ring depth and clamp profile |
| Offset/backspacing | Steering/brake clearance | Verify prior to purchase |
EFX’s thoughtful protector geometry rewards careful wheel selection. The result: fewer chips from custom wheels debris and cleaner rims after a muddy weekend.
Performance across terrain: mud to hard-pack
Field reports show fierce mud bite with predictable handling on hard-pack.
Deep mud traction without losing stability
In clay pits and gumbo, tall lugs and wide voids help with self-cleaning. This preserves deep-mud traction during long, throttle-heavy pulls.
The checkmark layout supports traction moves for pivots or backing out. This reduces spin and helps you maintain control in sticky situations.
Smooth ride on graded 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.
- Better flotation and rut-bridging than small knobbies, with modest steering effect.
- Feedback notes bite + poise that maintains momentum as terrain varies.
- UTV-focused design; many sizes keep 2.5″ depth for consistent off-road results.
| Terrain | Main benefit | Reason it matters |
|---|---|---|
| Mud | Self-cleaning lugs | Maintains traction during long pulls |
| Hard-pack | On-center stability | Cuts fatigue; sustains speed |
| Mixed terrain | Predictable transitions | Maintains momentum without twitch |
Buy with confidence: inventory status, lead times, and shipping in the United States
Knowing what ships now vs what has multi-week leads prevents last-minute stress.
Plenty of common fitments display “In Stock & Ready To Ship”. That means faster delivery and fewer scheduling surprises. Select big-diameter SKUs note 4–6 week leads—verify ETA in the selector.
U.S. shipments often ship free; certain SKUs are oversized. Oversized listings often require special handling, and carriers may ask for a signature or specific delivery 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.
- These are tubeless and non-DOT—mount for off-road use only and keep plugs and a compressor handy for field repairs.
