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
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. 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 standard 6-ply carcass supplies strong sidewall support across sizes. However, taller/heavier sizes add rotating mass and can affect acceleration and CVT response.
Verify clearance at full lock and bump, confirm offset with new rim diameters, and include payload (winches/cages) so suspension and gearing remain 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 | Impact | Action |
|---|---|---|
| Overall diameter | Clearance and approach angles | Go larger for deep mud and ruts |
| Section width | Cut-through vs float | Use narrower to punch through mud |
| Weight | Rotational mass, acceleration | Check clutching/gearing accordingly |

- Confirm stock status—numerous sizes ship now; others show 4–6 week waits.
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
The checkmark pattern interlocks lugs to create extra biting edges. It provides steady forward grip and dependable reverse traction for backing out.
Tall 2”+ lugs for superior mud grip
Tall, staggered 2″+ lugs clear mud fast and keep the contact patch stable across ruts. Reinforced grooves/shoulders add lateral hold so side-hilling feels planted.
The ultra-deep lip protector shields bead lips, channeling rocks/roots away. That armoring custom wheels limits cosmetic damage and helps keep the bead sealed in harsh terrain.
| Design | Benefit | Notes |
|---|---|---|
| Checkmark geometry | Two-way traction | Predictable extraction and braking |
| 2″+ lugs | Mud evacuation and stability | Confidence in deep muck |
| Lip protector | Wheel protection | Helps avoid rim rash and burps |
Construction and compliance details
Build choices determine how a mud-focused tire behaves under 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.
The lineup is tubeless and optimized for UTV use. Tubeless mounting eases installation, lowers rotating mass versus tubes, and lets you manage punctures quickly with plugs.
Compliance, loads, and handling notes
- 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.
| Spec | Effect | Action |
|---|---|---|
| 6-ply casing | Load stability and strength | Verify load ratings vs GVWR |
| Tubeless construction | Simpler installs; quick plug repairs | Keep plugs and a compressor on board |
| Non-DOT | 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.
Verify load ratings/SKU notes to confirm support for passengers, cargo, and riding style. That helps avoid delivery surprises and preserves predictable results.
Wheel fitment guidance for custom builds
Matching rim and profile correctly protects finishes and sharpens 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. 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: debris control in motion
Set offset/backspacing to clear steering/knuckles while maintaining bead protection. Test-fit a corner to verify full-lock caliper clearance.
- 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.
- Aggressive/wide builds often benefit from fender extensions to manage fling.
| Check | Reason | Quick Action |
|---|---|---|
| Section width vs rim lip | Prevents pinching and protects finish | Match inner/outer lip measurements |
| Beadlock ring/hardware | Can interfere with protector coverage | Check ring depth and clamp geometry |
| Offset & backspace | Steering/brake clearance | Confirm before final purchase |
Thoughtful protector geometry from EFX benefits smart wheel choices. Result: fewer chips from custom wheels debris and cleaner rims after muddy weekends.
Performance across terrain: mud to hard-pack
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 pits and gumbo, tall lugs and wide voids help with self-cleaning. That keeps deep mud traction during long, throttle-heavy pulls.
The checkmark tread supports traction drive moves when you need to pivot or back 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.
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.
- Rider feedback highlights a blend of bite and poise that keeps group rides moving as terrain shifts.
- UTV-focused design; many sizes keep 2.5″ depth for consistent off-road results.
| Terrain | Main benefit | Reason it matters |
|---|---|---|
| Deep mud | Self-clearing lugs | Maintains traction during long pulls |
| Hard-pack | On-center stability | Cuts fatigue; sustains speed |
| Mixed runs | Predictable feel | Keeps momentum without twitchiness |
Inventory, lead times, and U.S. shipping: buy with confidence
Spotting in-stock vs lead-time items early avoids last-minute problems.
