motohavok tire size: how to choose the perfect fit right now
Choose correctly by reading sidewall numbers and aligning them with your wheels and goals.
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. Match that final number to your rim to prevent extra expense and fitment problems.
Selecting by terrain balance
Choose if you prefer peak mud traction or steadier hard-pack manners. 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. 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.
- Decode sizes fast to match your wheel and save money.
- Select diameter to gain clearance and width to control cut-through/float.
- Account for driveline and steering impacts prior to purchase.
| Item | Impact | What to do |
|---|---|---|
| Diameter | Clearance and approach angles | Choose larger for deep mud runs |
| Tire width | Penetration vs flotation | Run narrower to cut to firm base |
| Tire weight | Rotational load and acceleration | Verify clutching and gearing |

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. This yields predictable bite going forward and reliable reverse traction for extraction.
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 | Purpose | Notes |
|---|---|---|
| Checkmark pattern | Two-way traction | Predictable extraction and braking |
| Tall lugs | Mud evacuation and stability | Keeps momentum in deep sections |
| 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.
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.
All sizes are tubeless and tuned for UTV duty. Tubeless mounting eases installation, lowers rotating mass versus tubes, and lets you manage punctures quickly with plugs.
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.
- Some SKUs are oversized items—plan for special handling, storage, and shipping on larger orders.
| Spec | Effect | Recommended 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 rating | 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. 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. Doing so prevents surprises at delivery and maintains predictable performance.
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. 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.
With beadlocks, confirm ring/clamp shapes so the protector clears hardware on wide/concave faces.
How to pair with armoring custom wheels for debris management
Set offset/backspacing to clear steering/knuckles while maintaining bead protection. Dry-fit one corner to confirm caliper clearance at full lock.
- 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.
- Aggressive/wide builds often benefit from fender extensions to manage fling.
| Check | Why it Matters | Quick Action |
|---|---|---|
| Width vs rim lips | Prevents pinching and protects finish | Compare inner/outer lip sizes |
| Beadlock hardware | May interfere with protector | Check ring depth and clamp geometry |
| Offset & backspace | Steering/brake clearance | Confirm before final purchase |
Thoughtful protector geometry from EFX benefits smart wheel choices. Outcome: reduced custom wheel rash and cleaner rims after mud runs.
From mud to hard-pack: performance overview
In real rides, this lineup brings strong muck grip with predictable behavior on firm ground.
Serious mud grip with consistent 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. It cuts wheelspin and keeps control when stuck.
Composed hard-pack ride on trails and flats
On graded trails the carcass spreads load across the contact patch. Hands and shoulders feel less chatter, so long days stay comfortable.
Transitions from puddles to hard-pan feel predictable. You get stability—not twitch—so connectors can be taken with confidence.
- Better flotation and rut-bridging than small knobbies, with modest steering effect.
- Riders report a balance of bite and poise that keeps groups moving as terrain changes.
- UTV-focused design; many sizes keep 2.5″ depth for consistent off-road results.
| Terrain | Primary Benefit | Why it Matters |
|---|---|---|
| Deep mud | Self-clearing lugs | Maintains traction during long pulls |
| Hard-pack | On-center stability | Reduces rider fatigue; keeps speed |
| Mixed runs | Predictable transitions | Keeps momentum without twitchiness |
