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

For example, 35×8.5-22 indicates ~35″ overall, 8.5″ wide, for a 22″ rim. Keep the wheel diameter the same as your current rim to avoid added costs and fitment issues.

Pick based on terrain needs

Decide whether you want maximum deep mud traction or a more composed hard-pack ride. Bigger diameters raise chassis height for ruts/bogs.

An 8.5″ section can cut through to firm base, whereas wider sections add stability on level ground.

Clearance, gearing, and weight considerations for your UTV

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 sizes fast to match your wheel and save money.
• Choose diameter for clearance; use width to tune cut-through vs float.
• Plan for driveline and steering changes before upgrading.

Variable	Effect	Action
Diameter	Ground clearance, approach angle	Choose larger for deep mud runs
Tire width	Penetration vs flotation	Run narrower to cut to firm base
Tire weight	Rotational mass, acceleration	Verify clutching and gearing

Quick takeaways:

• Use the chart to compare real weights and loads so you can gauge acceleration feel and support for passengers and cargo.
• Uniform tread depth lets lugs dig in mud yet stay predictable on hard-pack.
• Moving to low-30s boosts clearance with minor mass increase; 42″ ups mass and payload.
• 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. The EFX design focuses on real-world performance from mud to hard-pack.

Industry-first checkmark tread for traction in drive and reverse

Checkmark geometry interlocks blocks for added biting edges. It provides steady forward grip and dependable reverse traction for backing out.

Tall 2”+ lugs for superior mud grip

Staggered 2″+ lugs self-clean quickly and stabilize the patch in ruts. Reinforced grooves/shoulders add lateral hold so side-hilling feels planted.

The ultra-deep lip protector shields bead lips, channeling rocks/roots away. This armoring custom wheels reduces cosmetic damage and helps maintain a sealed bead in punishing terrain.

Feature	Benefit	Why it helps
Checkmark geometry	Two-way traction	Controlled recoveries and braking
Tall lugs	Mud evacuation and stability	Keeps momentum in deep sections
Lip protector	Rim defense	Reduces rim damage and burping

Construction and compliance details

Construction decisions shape mud-tire behavior under real UTV stresses.

At its core is a rugged 6-ply carcass on a bias-belt platform. You get sidewall stiffness for stability plus flex to contour over ruts and obstacles.

All sizes are tubeless and tuned for UTV duty. Tubeless fitment speeds installs, cuts rotating mass vs tubes, and enables quick plug repairs.

Load and handling considerations

• 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.
• Oversized SKUs may need special handling, storage, and shipping arrangements.

Specification	Effect	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 rating	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. This engineered balance supports the ag-style performance claim—real structure beyond big lugs.

Verify load ratings/SKU notes to confirm support for passengers, cargo, and riding style. Doing so prevents surprises at delivery and maintains predictable performance.

Wheel fitment guidance for custom builds

Get rim/profile fit right to protect finishes and refine handling.

Select a section width that suits your rim 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. Good alignment optimizes protection for custom wheels and avoids exposed lips.

On beadlocks, verify ring thickness and clamp geometry to clear the protector around hardware.

How to pair with armoring custom wheels for debris management

Consider offset and backspacing so the protector clears tie rods and knuckles while still shielding the bead. Dry-fit one 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.
• Aggressive/wide builds often benefit from fender extensions to manage fling.

Check	Reason	Action
Section width vs rim lip	Avoids pinching and protects finish	Match inner/outer lip measurements
Beadlock hardware	Can interfere with protector coverage	Measure ring depth and clamp profile
Offset/backspacing	Steering/brake clearance	Confirm before final purchase

EFX’s thoughtful protector geometry rewards careful wheel selection. 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.

Deep mud traction without losing stability

Tall lugs and wide voids self-clear in clay pits and gumbo. It sustains deep-mud bite through long, heavy-throttle sections.

Checkmark geometry aids traction when pivoting or reversing. That limits spin and helps maintain control in sticky spots.

Smooth ride on graded trails and flats

The carcass distributes load evenly on graded trails. Rider fatigue drops as chatter is reduced, keeping long days comfortable.

Transitions from puddles to hard-pan feel predictable. Stability beats twitchiness, helping carry speed on connectors.

• Better flotation and rut-bridging than small knobbies, with modest steering effect.
• 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	Why it Matters
Deep mud	Self-clearing lugs	Keeps traction through long pulls
Hard-pack	On-center stability	Cuts fatigue; sustains speed
Mixed runs	Predictable feel	Maintains momentum without twitch

Many popular fitments show “In Stock & Ready To Ship” on retail pages. This leads to quicker delivery and fewer planning hiccups. A handful of larger options display a 4–6 week lead time—always check the selector to confirm ETA for your chosen configuration.

U.S. shipments often ship free; certain SKUs are oversized. Oversized items may need special handling; carriers can require signatures or scheduled windows.

Quick shipping and delivery notes

• Plan ahead for lead-time SKUs if you’re timing a trip; order earlier to ensure your matter terrain plans stay on track.
• Expect tracking updates from retailers once a set ships; oversized deliveries may need someone present to accept.
• Double-check wheel specs so the deep lip protector and armoring custom wheels work as intended.
• These are tubeless and non-DOT—mount for off-road use only and keep plugs and a compressor handy for field repairs.
