MotoHavok tire size — choosing the right fit now
Choose correctly by reading sidewall numbers and aligning them with your wheels and goals.
Decode sizing & match 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.
Choose by terrain balance
Decide whether you want maximum deep mud traction or a more composed hard-pack ride. Bigger diameters raise chassis height for ruts/bogs.
Narrower sections (e.g., 8.5″) slice down to firmer layers; wider choices spread contact for stability on flats.
Mind clearance, gearing, and weight
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 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 | Effect | Action |
|---|---|---|
| Diameter | Ground clearance, approach angle | Go larger for deep mud and ruts |
| Section width | Penetration vs flotation | Use narrower to punch through mud |
| Tire weight | Rotational load and acceleration | Verify clutching and gearing |

- Verify stock and shipping—many sizes are in; some carry 4–6 week leads.
Engineering that grips: tread pattern, lug design, and wheel protection
Here the design focuses on grip—each tread element and protector is purposeful. EFX targets practical performance from muck to hard-pack.
Industry-first checkmark tread for traction in drive and reverse
Checkmark geometry interlocks blocks for added biting edges. That gives predictable traction when you head forward and when you need traction drive reverse to extract from a hole.
Enormous 2”+ lugs for unparalleled deep mud performance
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.
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.
| Design | Purpose | Why it helps |
|---|---|---|
| Checkmark pattern | Forward and reverse traction | Controlled recoveries and braking |
| 2″+ lugs | Self-cleaning with stability | Confidence in deep muck |
| Lip protector | Wheel protection | Helps avoid rim rash and burps |
Construction & 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. This gives sidewall stiffness for stability while allowing enough flex to conform to ruts and obstacles.
All sizes are tubeless and tuned for UTV duty. Going tubeless simplifies mounting, reduces rotating mass, and supports fast plug-type fixes.
Compliance & load/handling notes
- Non-DOT compliance means these are for off-road and private-property use only; do not use on public roads where DOT is required.
- 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.
| Spec | Effect | Action |
|---|---|---|
| 6-ply carcass | Load stability and strength | Verify load ratings vs GVWR |
| Tubeless build | Easier mounting; puncture repair options | Carry plugs + portable compressor |
| Non-DOT rating | Not for public road use | Limit use to trails and private land |
Even with an aggressive profile, the casing aims for a more composed ride vs many ag-style options. Engineering—not just big lugs—underpins the ag-style performance balance.
Check load ratings and SKU notes before ordering so your choice supports passengers, gear, and the way you ride. This reduces surprises at delivery and keeps performance predictable.
Fitment guidance for wheels and custom builds
Get rim/profile fit right to protect finishes and refine 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.
Check bead/flange alignment so the deep lip protector fully covers the rim. 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. Dry-fit a corner to confirm caliper clearance at full lock.
- Run hub-centric rings and quality lugs for concentric fit and less vibration.
- Match rim/profile to balance mud grip and smooth trail manners.
- Wide-stance setups may require fender extensions to limit lug fling.
| Check | Why it Matters | Action |
|---|---|---|
| Width vs rim lips | Prevents pinching and protects finish | Compare inner/outer lip sizes |
| Beadlock ring/hardware | May interfere with protector | Measure ring depth and clamp profile |
| Offset & backspace | Clearance for steering and brakes | Confirm before final purchase |
EFX’s protector geometry pays off when wheels are chosen carefully. Outcome: reduced custom wheel rash and cleaner rims after mud runs.
Performance by terrain: mud → hard-pack
Field reports show fierce mud bite with predictable handling on hard-pack.
Serious mud grip with consistent stability
In clay/gumbo, tall lugs and wide voids self-clean effectively. That keeps 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
The carcass distributes load evenly on graded trails. Hands and shoulders feel less chatter, so long days stay comfortable.
Going from wet sections to hard-pan remains predictable. Stability beats twitchiness, helping carry speed on connectors.
- Flotation/rut bridging beat small knobbies with minimal steering penalty.
- 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 |
|---|---|---|
| Mud | Self-cleaning 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
Spotting in-stock vs lead-time items early avoids last-minute problems.
Many popular fitments show “In Stock & Ready To Ship” on retail pages. 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. shipments often ship free; certain SKUs are oversized. Expect special handling on oversized SKUs; couriers may require signatures/windows.
