How to choose your MotoHavok tire size today
Select accurately by decoding sidewall sizes and matching them to wheel specs and ride priorities.
Reading size codes to match your wheels
A size such as 35×8.5-22 equals ~35″ OD, 8.5″ width, on a 22″ wheel. Match that final number to your rim to prevent extra expense and fitment problems.
Choose by terrain balance
Decide between maximum mud bite or a calmer hard-pack feel. Larger diameters lift the chassis 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
The standard 6-ply carcass supplies strong sidewall support across sizes. 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 sizes fast to match your wheel and save money.
- Choose diameter for clearance; use width to tune cut-through vs float.
- Account for driveline and steering impacts prior to purchase.
| Variable | Effect | Action |
|---|---|---|
| Overall diameter | Ground clearance, approach angle | Go larger for deep mud and ruts |
| Tire width | Penetration vs flotation | Use narrower to punch through mud |
| Weight | Rotational load and acceleration | Check clutching/gearing accordingly |

Quick takeaways:
- Leverage the chart to weigh acceleration feel vs passenger/cargo support.
- A consistent 2.5″ depth maintains mud bite and predictable hard-pack contact.

Engineering for grip: tread, lugs & wheel protection
Here the design focuses on grip—each tread element and protector is purposeful. The EFX design focuses on real-world performance from mud 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.
Enormous 2”+ lugs for unparalleled deep mud performance
Staggered 2″+ lugs self-clean quickly and stabilize the patch in ruts. Reinforced grooves and shoulder blocks add lateral grip so side-hilling feels planted, not sketchy.
The ultra-deep lip protector shields bead lips, channeling rocks/roots away. This protection for custom wheels trims cosmetic rash and helps maintain bead seal off-road.
| Design | Benefit | Why it helps |
|---|---|---|
| Checkmark pattern | Two-way traction | Predictable extraction and braking |
| 2″+ lugs | Self-cleaning with stability | Confidence in deep muck |
| Deep wheel lip protector | Rim defense | Reduces rim damage and burping |
Build and compliance notes
Construction choices drive how a mud-focused wheel performs under real UTV loads.
At its core is a rugged 6-ply carcass on a bias-belt platform. You get sidewall stiffness for stability plus flex to contour over ruts and obstacles.
The lineup is tubeless and optimized for UTV use. Going tubeless simplifies mounting, reduces rotating mass, and supports fast plug-type fixes.
Compliance & load/handling notes
- 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.
| Specification | Impact | Action |
|---|---|---|
| 6-ply carcass | Load stability and strength | Match load ratings to your GVWR |
| Tubeless build | Easier mounting; puncture repair options | 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. 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. That helps avoid delivery surprises and preserves predictable results.
Fitment guidance for wheels and custom builds
Get rim/profile fit right to protect finishes and refine handling.
Select a section width that suits your rim 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. Proper alignment maximizes armoring custom wheels while preventing exposed edges.
For beadlocks, double-check ring thickness and clamp geometry so the protector clears hardware on concave or wide faces.
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 one corner to confirm caliper clearance at full lock.
- Use hub-centric rings and quality lugs to keep the assembly concentric and reduce vibration.
- Match rim/profile to balance mud grip and smooth trail manners.
- Wide-stance setups may require fender extensions to limit lug fling.
| Fitment Check | Why it Matters | Quick Action |
|---|---|---|
| Width vs rim lips | Prevents pinching and protects finish | Match inner/outer lip measurements |
| Beadlock ring/hardware | May interfere with protector | Check ring depth and clamp geometry |
| Offset/backspacing | Steering/brake clearance | Confirm before final purchase |
EFX’s thoughtful protector geometry rewards careful wheel selection. Outcome: reduced custom wheel rash and cleaner rims after mud runs.
Performance across terrain: mud to hard-pack
In real rides, this lineup brings strong muck grip with predictable behavior on firm ground.
Serious mud grip with consistent 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.
Composed hard-pack ride on trails and flats
On graded trails the carcass spreads load across the contact patch. With less chatter, long days feel more 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.
- 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.
| Surface | Primary Benefit | Why 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 feel | Keeps momentum without twitchiness |
Buy with confidence: inventory status, lead times, and shipping in the United States
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.
Shipping & 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 before ordering so the feature ultra deep lip protector and armoring custom wheels benefit your rims right away.
- Tubeless and non-DOT—off-road only; carry plugs and a compressor for field fixes.
| Category | Typical 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 | Verify ETA; plan special delivery handling |
| U.S. shipping policy | Free shipping on many SKUs | Review cart for oversized surcharges |
| Notes | Tubeless, non-DOT | Off-road only; carry repair gear |
Final Thoughts
Make the call by mapping your needs to published specs and fitment notes.
You get 2″+ lugs and a 6-ply bias carcass for deep-mud grip, with calm hard-pack behavior. The ultra deep wheel lip protector also gives real wheel armor for custom builds.
Use the published weights, load ratings, and 2.5″ tread depth to pick a wheel diameter and section width that meet clearance and load needs. Double-check clutching/gearing after upsizing.
Numerous common sizes ship now; others carry 4–6 week waits. Confirm availability, then order with confidence and get back to riding.
