MotoHavok tire size — choosing the right fit now
Choose correctly by reading sidewall numbers and aligning them with your wheels and goals.
Reading sizes and matching 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.
Pick based on terrain needs
Decide whether you want maximum deep mud traction or a more composed hard-pack ride. Larger diameters lift the chassis 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 & weight: key considerations
The standard 6-ply carcass supplies strong sidewall support across sizes. But taller, heavier options add rotational mass and can change acceleration and CVT behavior.
Confirm steering clearance at full lock/compression, verify offsets if wheel diameter changes, and factor added payload (winch/cage) to keep suspension/gearing balanced.
- Learn the size code so you can match wheels and curb costs.
- 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 | Clearance and approach angles | Choose larger for deep mud runs |
| Tire width | Cut-through vs float | Use narrower to punch through mud |
| Weight | Rotational mass, acceleration | Check clutching/gearing accordingly |

Engineering that grips: tread pattern, lug design, and wheel protection
Engineering here puts grip first, so every tread, lug, and protector earns its place. EFX tunes for real-world performance across mud and 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
With 2″+ staggered lugs, mud sheds quickly and the patch stays stable 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.
| Design | Purpose | Notes |
|---|---|---|
| Checkmark geometry | Forward and reverse traction | Predictable extraction and braking |
| Tall lugs | Self-cleaning with stability | Confidence in deep muck |
| 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. 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.
- Some SKUs are oversized items—plan for special handling, storage, and shipping on larger orders.
| Spec | Effect | Action |
|---|---|---|
| 6-ply casing | Load stability and strength | Verify load ratings vs GVWR |
| Tubeless build | Simpler installs; quick plug repairs | Carry plugs + portable compressor |
| Non-DOT | Not for public road use | Limit use to trails and private land |
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.
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 tips for wheels and custom setups
Matching rim and profile correctly protects finishes and sharpens handling.
Choose a section width that aligns with your wheel 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. Correct alignment maximizes armoring custom wheels and prevents exposed spots.
On beadlocks, verify ring thickness and clamp geometry to clear the protector around hardware.
Pairing with armoring custom wheels to manage debris in motion
Mind offset/backspacing so the protector clears tie rods/knuckles yet still shields the bead. Test-fit a corner to verify full-lock caliper clearance.
- Hub-centric rings + quality lugs help keep things concentric and smooth.
- 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.
| Check | Why it Matters | Quick Action |
|---|---|---|
| Section width vs rim lip | Avoids pinching and protects finish | Compare inner/outer lip sizes |
| Beadlock hardware | Can interfere with protector coverage | Measure ring depth and clamp profile |
| Offset/backspacing | Steering/brake clearance | Verify prior to purchase |
EFX’s thoughtful protector geometry rewards careful wheel selection. Result: fewer chips from custom wheels debris and cleaner rims after muddy weekends.
From mud to hard-pack: performance overview
Real-world runs show the pack delivers both fierce grip in muck and predictable manners on firm ground.
Deep mud traction without losing 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. It cuts wheelspin and keeps control when stuck.
Smooth hard-pack ride quality for trails and flats
On graded routes, the carcass spreads load over the patch. With less chatter, long days feel more comfortable.
Transitions from puddles to hard-pan feel predictable. You get stability—not twitch—so connectors can be taken with confidence.
- Flotation/rut bridging beat small knobbies with minimal steering penalty.
- Feedback notes bite + poise that maintains momentum as terrain varies.
- UTV-focused design; many sizes keep 2.5″ depth for consistent off-road results.
| Surface | Main benefit | Why it Matters |
|---|---|---|
| Mud | Self-cleaning 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
Spotting in-stock vs lead-time items early avoids last-minute problems.
A lot of popular sizes list “In Stock & Ready To Ship” on retailer pages. That yields faster delivery with fewer scheduling surprises. Some larger sizes show 4–6 week leads—check the selector for ETA on your exact configuration.
In the U.S., many orders qualify for free shipping, but some SKUs are oversized. Oversized items may need special handling; carriers can require signatures or scheduled windows.
Shipping & delivery 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 pre-order so the ultra-deep lip protector and armoring custom wheels protect your rims immediately.
- Non-DOT tubeless—off-road use; keep a plug kit and compressor ready.
