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
Sizes like 35×8.5-22 mean about 35″ overall diameter, 8.5″ section width, and a 22″ wheel. Match the wheel number to your current wheel to avoid extra cost and fitment headaches.
Selecting by terrain balance
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, such as 8.5″, help the profile cut through mud to firmer layers, while wider choices spread contact for stability on flats.
Mind clearance, gearing, and weight
The standard 6-ply carcass supplies strong sidewall support across sizes. Yet bigger/heavier tires increase rotational mass, impacting acceleration and CVT feel.
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.
- Pick diameter for clearance; choose width for how the tread digs into mud.
- Plan for driveline and steering changes before upgrading.
| Item | Effect | Action |
|---|---|---|
| Overall diameter | Ground clearance, approach angle | Choose larger for deep mud runs |
| Section width | Cut-through vs float | Use narrower to punch through mud |
| Weight | Rotational mass, acceleration | Verify clutching and gearing |

Engineering for grip: tread, lugs & wheel protection
Here the design focuses on grip—each tread element and protector is purposeful. EFX tunes for real-world performance across mud and hard-pack.
First-of-its-kind checkmark tread: traction forward & reverse
The checkmark pattern interlocks lugs to create extra biting edges. It provides steady forward grip and dependable reverse traction for backing out.
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.
An ultra deep wheel lip protector shields bead lips and channels rocks and roots away from the bead area. This protection for custom wheels trims cosmetic rash and helps maintain bead seal off-road.
| Design | Benefit | Why it helps |
|---|---|---|
| Checkmark geometry | Forward and reverse traction | Predictable extraction and braking |
| Tall lugs | Mud evacuation and stability | Confidence in deep muck |
| Lip protector | Wheel protection | Reduces rim damage and burping |
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. 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 fitment speeds installs, cuts rotating mass vs tubes, and enables quick plug repairs.
Compliance, loads, and 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.
- Weights vary by SKU (~36–81 lb); most list 2.5″ tread depth and max loads ~740–1390 lb.
- Some SKUs are oversized items—plan for special handling, storage, and shipping on larger orders.
| Specification | Impact | Recommended action |
|---|---|---|
| 6-ply carcass | Load stability and strength | Match load ratings to your GVWR |
| Tubeless build | Easier mounting; puncture repair options | Keep plugs and a compressor on board |
| 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. Engineering—not just big lugs—underpins the ag-style performance balance.
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
A proper match between rim and profile protects finishes and improves handling.
Select a section width that suits your rim 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. 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 a corner to confirm caliper clearance at full lock.
- Use hub-centric rings and quality lugs to keep the assembly concentric and reduce vibration.
- 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.
| Fitment Check | Why it Matters | Quick Action |
|---|---|---|
| Width vs rim lips | Avoids pinching and protects finish | Compare inner/outer lip sizes |
| Beadlock hardware | Can interfere with protector coverage | Measure ring depth and clamp profile |
| Offset & backspace | Clearance for steering and brakes | Verify prior to purchase |
EFX’s protector geometry pays off when wheels are chosen carefully. The result: fewer chips from custom wheels debris and cleaner rims after a muddy weekend.
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 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. It cuts wheelspin and keeps control when stuck.
Smooth hard-pack ride quality for 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. You get stability—not twitch—so connectors can be taken with confidence.
- 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.
- UTV-focused design; many sizes keep 2.5″ depth for consistent off-road results.
| Terrain | Primary Benefit | Reason it matters |
|---|---|---|
| Mud | Self-clearing lugs | Maintains traction during long pulls |
| Hard-pack | On-center stability | Cuts fatigue; sustains speed |
| Mixed terrain | Predictable feel | Maintains momentum without twitch |
Buy with confidence: inventory status, lead times, and shipping in the United States
Spotting in-stock vs lead-time items early avoids last-minute problems.
