How to choose your MotoHavok tire size today
Choose correctly by reading sidewall numbers and aligning them with your wheels and goals.
Reading size codes to match your wheels
A size such as 35×8.5-22 equals ~35″ OD, 8.5″ width, on a 22″ wheel. Keep the wheel diameter the same as your current rim to avoid added costs and fitment issues.
Selecting by terrain balance
Decide whether you want maximum deep mud traction or a more composed hard-pack ride. Bigger diameters raise chassis height for ruts/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.
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 size codes quickly to match your rim and avoid extra cost.
- Pick diameter for clearance; choose width for how the tread digs into mud.
- Plan for driveline and steering changes before upgrading.
| Item | Impact | What to do |
|---|---|---|
| Diameter | Ground clearance, approach angle | Go larger for deep mud and ruts |
| Section width | Penetration vs flotation | Run narrower to cut to firm base |
| Weight | Rotational load and acceleration | Check clutching/gearing accordingly |

Engineering for grip: tread, lugs & wheel protection
Engineering here puts grip first, so every tread, lug, and protector earns its place. EFX targets practical performance from muck to hard-pack.
Checkmark tread: traction in both directions
The checkmark pattern interlocks lugs to create extra biting edges. That gives predictable traction when you head forward and when you need traction drive reverse to extract from a hole.
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.
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 | Why it helps |
|---|---|---|
| Checkmark geometry | Forward and reverse 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
Construction choices drive how a mud-focused wheel performs under real UTV loads.
At its core is a rugged 6-ply carcass 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 & 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.
- Certain SKUs are oversized; plan special handling, storage, and shipping.
| Specification | Effect | Action |
|---|---|---|
| 6-ply carcass | Load stability and strength | Match load ratings to your GVWR |
| Tubeless construction | Simpler installs; quick plug repairs | Carry plugs + portable compressor |
| Non-DOT | Off-road use only | 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. This reduces surprises at delivery and keeps performance predictable.
Fitment guidance for wheels and custom builds
Get rim/profile fit right to protect finishes and refine handling.
Pick a section width that matches rim lips. Common 8.5 options work well on many deep wheel rims without pinching or ballooning.
Confirm bead/flange alignment so the ultra-deep lip protector overlays 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
Consider offset and backspacing so the protector clears tie rods and knuckles while still shielding the bead. 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 traction smooth feel by matching the rim and profile for both swamp runs and trail cruising.
- Wide-stance setups may require fender extensions to limit lug fling.
| Check | Reason | Action |
|---|---|---|
| Section width vs rim lip | Prevents pinching and protects finish | Match inner/outer lip measurements |
| Beadlock ring/hardware | May interfere with protector | Measure ring depth and clamp profile |
| Offset/backspacing | Steering/brake clearance | Verify prior to purchase |
Thoughtful protector geometry from EFX benefits smart wheel choices. Outcome: reduced custom wheel rash and cleaner rims after mud runs.
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 layout supports traction moves for pivots or backing out. This reduces spin and helps you maintain control in sticky situations.
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.
When you hop from puddles to hard-pan, the contact patch transitions predictably. The rig feels stable instead of twitchy, which helps you carry speed on connectors.
- Flotation and rut bridging improve over small knobbies without big steering penalties.
- Feedback notes bite + poise that maintains momentum as terrain varies.
- UTV-specific; numerous options maintain 2.5″ depth for steady off-road behavior.
| Surface | Main 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 transitions | Keeps momentum without twitchiness |
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.
