MotoHavok tire size — choosing the right fit now
Pick the right fit by learning to read the numbers stamped on the sidewall and matching them to your wheels and ride goals.
Reading sizes and matching to wheel diameter
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.
Selecting by terrain balance
Decide between maximum mud bite or a calmer hard-pack feel. 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.
Clearance, gearing & weight: key considerations
A 6-ply carcass provides stout sidewall support throughout the range. However, taller/heavier sizes add rotating mass and can affect acceleration and CVT response.
Confirm steering clearance at full lock/compression, verify offsets if wheel diameter changes, and factor added payload (winch/cage) to keep suspension/gearing balanced.
- Decode size codes quickly to match your rim and avoid extra cost.
- Choose diameter for clearance; use width to tune cut-through vs float.
- Account for driveline and steering impacts prior to purchase.
| Item | Effect | Action |
|---|---|---|
| Diameter | Clearance and approach angles | Go larger for deep mud and ruts |
| Section width | Cut-through vs float | Run narrower to cut to firm base |
| Weight | Rotational load and acceleration | Verify clutching and gearing |

Engineering that grips: tread pattern, lug design, and wheel protection
This engineering prioritizes grip; every tread block, lug, and protector has a job. EFX targets practical performance from muck to hard-pack.
Industry-first checkmark tread for traction in drive and reverse
A checkmark layout interlocks lugs to increase edges. That gives predictable traction when you head forward and when you need traction drive reverse to extract from a hole.
2”+ lugs for standout deep-mud bite
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.
An ultra deep wheel lip protector shields bead lips and channels rocks and roots away from the bead area. This armoring custom wheels reduces cosmetic damage and helps maintain a sealed bead in punishing terrain.
| Design | Benefit | Notes |
|---|---|---|
| Checkmark pattern | Two-way traction | Predictable extraction and braking |
| Tall lugs | Self-cleaning with stability | Confidence in deep muck |
| Deep wheel lip protector | Wheel protection | Helps avoid rim rash and burps |
Construction & compliance details
Construction choices drive how a mud-focused wheel performs under real UTV loads.
It uses a stout 6-ply bias-belt carcass at the core. 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.
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.
- Weights vary by SKU (~36–81 lb); most list 2.5″ tread depth and max loads ~740–1390 lb.
- Oversized SKUs may need special handling, storage, and shipping arrangements.
| Specification | Impact | Recommended action |
|---|---|---|
| 6-ply carcass | Strength and stability under load | Verify load ratings vs GVWR |
| Tubeless build | Simpler installs; quick plug repairs | Carry plugs + portable compressor |
| Non-DOT | Off-road use only | Keep usage off public roads |
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.
Wheel fitment guidance for custom builds
A proper match between rim and profile protects finishes and improves 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.
Check bead/flange alignment so the deep lip protector fully covers the rim. 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.
Pairing with armoring custom wheels: debris control in motion
Consider offset and backspacing so the protector clears tie rods and knuckles while still shielding the bead. 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 bite with smooth feel by pairing rim/profile for swamps and trails.
- Aggressive/wide builds often benefit from fender extensions to manage fling.
| Fitment Check | Reason | Action |
|---|---|---|
| Width vs rim lips | Avoids pinching and protects finish | Match inner/outer lip measurements |
| Beadlock hardware | Can interfere with protector coverage | Check ring depth and clamp geometry |
| Offset/backspacing | Clearance for steering and brakes | Verify prior to 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.
Unparalleled deep mud traction without sacrificing stability
In clay/gumbo, tall lugs and wide voids self-clean effectively. This preserves deep-mud traction during long, throttle-heavy pulls.
Checkmark geometry aids traction when pivoting or reversing. That limits spin and helps maintain control in sticky spots.
Smooth hard-pack ride quality for trails and flats
On graded trails the carcass spreads load across the contact patch. Rider fatigue drops as chatter is reduced, keeping long days comfortable.
Going from wet sections to hard-pan remains predictable. You get stability—not twitch—so connectors can be taken with confidence.
- 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 | Why it Matters |
|---|---|---|
| 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 |
