How to choose your MotoHavok tire size today

Choose correctly by reading sidewall numbers and aligning them with your wheels and goals.

Reading sizes and matching to wheel diameter

Sizes like 35×8.5-22 mean about 35″ overall diameter, 8.5″ section width, and a 22″ wheel. Keep the wheel diameter the same as your current rim to avoid added costs and fitment issues.

Choose by terrain balance

Choose if you prefer peak mud traction or steadier hard-pack manners. 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.

Mind clearance, gearing, and weight

The common 6-ply carcass construction gives strong sidewall support across the lineup. But taller, heavier options add rotational mass and can change acceleration and CVT behavior.

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.
• Select diameter to gain clearance and width to control cut-through/float.
• Plan ahead for steering/driveline effects.

Variable	Effect	What to do
Overall diameter	Ground clearance, approach angle	Go larger for deep mud and ruts
Tire width	Cut-through vs float	Use narrower to punch through mud
Weight	Rotational mass, acceleration	Check clutching/gearing accordingly

Fast conclusions:

• Use the chart to compare real weights and loads so you can gauge acceleration feel and support for passengers and cargo.
• A consistent 2.5″ depth maintains mud bite and predictable hard-pack contact.
• Moving to low-30s boosts clearance with minor mass increase; 42″ ups mass and payload.
• Check availability and free shipping notes—many are in stock, some list 4–6 week lead times.

Engineering that grips: tread pattern, lug design, and wheel protection

This engineering prioritizes grip; every tread block, lug, and protector has a job. The EFX design focuses on real-world performance from mud to hard-pack.

Checkmark tread: traction in both directions

A checkmark layout interlocks lugs to increase edges. It provides steady forward grip and dependable reverse traction for backing out.

Tall 2”+ lugs for superior mud grip

With 2″+ staggered lugs, mud sheds quickly and the patch stays stable in ruts. Reinforced shoulders and grooves boost lateral bite for planted side-hilling.

An ultra deep wheel lip protector shields bead lips and channels rocks and roots away from the bead area. That armoring custom wheels limits cosmetic damage and helps keep the bead sealed in harsh terrain.

Design	Purpose	Notes
Checkmark pattern	Forward and reverse traction	Controlled recoveries and braking
2″+ lugs	Self-cleaning with stability	Keeps momentum in deep sections
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. This gives sidewall stiffness for stability while allowing enough flex to conform to ruts and obstacles.

The lineup is tubeless and optimized for UTV use. Going tubeless simplifies mounting, reduces rotating mass, and supports fast plug-type fixes.

Load and handling considerations

• Non-DOT: use off-road or on private land only, not public roads requiring 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.

Specification	Effect	Recommended action
6-ply carcass	Load stability and strength	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

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

Matching rim and profile correctly protects finishes and sharpens handling.

Select a section width that suits your rim lips. Common 8.5 options work well on many deep wheel rims without pinching or ballooning.

Check bead/flange alignment so the deep lip protector fully covers the rim. Proper alignment maximizes armoring custom wheels while preventing exposed edges.

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. Test-fit a corner to verify full-lock caliper clearance.

• Hub-centric rings + quality lugs help keep things concentric and smooth.
• Match rim/profile to balance mud grip and smooth trail manners.
• Wide stance builds may need fender extensions to control fling from aggressive lugs.

Fitment Check	Reason	Quick Action
Section width vs rim lip	Avoids pinching and protects finish	Match inner/outer lip measurements
Beadlock ring/hardware	May interfere with protector	Check ring depth and clamp geometry
Offset & backspace	Clearance for steering and brakes	Verify prior to purchase

Thoughtful protector geometry from EFX benefits smart wheel choices. The result: fewer chips from custom wheels debris and cleaner rims after a muddy weekend.

Performance by terrain: mud → hard-pack

Real-world runs show the pack delivers both fierce grip in muck and predictable manners on firm ground.

Unparalleled deep mud traction without sacrificing stability

In clay pits and gumbo, tall lugs and wide voids help with self-cleaning. It sustains deep-mud bite through long, heavy-throttle sections.

The checkmark tread supports traction drive moves when you need to pivot or back 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. Rider fatigue drops as chatter is reduced, keeping long days comfortable.

Going from wet sections to hard-pan remains predictable. The rig feels stable instead of twitchy, which helps you carry speed on connectors.

• 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.
• Designed for UTV use, many options keep a 2.5″ tread depth for consistent off-road performance.

Surface	Main benefit	Why it Matters
Mud	Self-clearing lugs	Keeps traction through long pulls
Hard-pack	On-center stability	Reduces rider fatigue; keeps speed
Mixed terrain	Predictable transitions	Keeps momentum without twitchiness

Buy with confidence: inventory status, lead times, and shipping in the United States

Knowing which items ship now versus those with multi-week lead times saves last-minute headaches.

Many popular fitments show “In Stock & Ready To Ship” on retail pages. That means faster delivery and fewer scheduling surprises. Some larger sizes show 4–6 week leads—check the selector for ETA on your exact configuration.

U.S. shipments often ship free; certain SKUs are oversized. Expect special handling on oversized SKUs; couriers may require signatures/windows.

Fast shipping notes

• If a trip is coming, plan for lead-time items and order early.
• You’ll get tracking once shipped; oversized items may need in-person acceptance.
• Verify wheel specs before ordering so the feature ultra deep lip protector and armoring custom wheels benefit your rims right away.
• Tubeless and non-DOT—off-road only; carry plugs and a compressor for field fixes.

Item	Common status	Buyer Action
Popular mid-range sizes	In stock & ready to ship	Order now; expect delivery in days
Large-diameter / oversized SKUs	Commonly 4–6 week lead time	Confirm ETA; plan for special delivery handling
U.S. shipping policy	Free shipping on many SKUs	Check cart for oversized fees before checkout
Product notes	Tubeless, non-DOT	Off-road only; carry repair gear
