How to choose your MotoHavok tire size today
Choose correctly by reading sidewall numbers and aligning them with your wheels and goals.
Decode sizing & match to wheel diameter
For example, 35×8.5-22 indicates ~35″ overall, 8.5″ wide, for a 22″ rim. Match that final number to your rim to prevent extra expense and fitment problems.
Pick based on terrain needs
Decide whether you want maximum deep mud traction or a more composed hard-pack ride. Going larger increases clearance for ruts and 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. Yet bigger/heavier tires increase rotational mass, impacting acceleration and CVT feel.
Confirm steering clearance at full lock/compression, verify offsets if wheel diameter changes, and factor added payload (winch/cage) to keep suspension/gearing balanced.
- Learn the size code so you can match wheels and curb costs.
- Select diameter to gain clearance and width to control cut-through/float.
- Account for driveline and steering impacts prior to purchase.
| Item | Effect | What to do |
|---|---|---|
| Diameter | Ground clearance, approach angle | Go larger for deep mud and ruts |
| Section width | Cut-through vs float | Use narrower to punch through mud |
| Weight | Rotational load and acceleration | Check clutching/gearing accordingly |

Quick takeaways:
- Use the chart to compare real weights and loads so you can gauge acceleration feel and support for passengers and cargo.
- The consistent tread depth helps the lugs claw through slop while keeping predictable contact on hard-pack.
- Jumping into the low-30s gains clearance without a huge weight penalty; the 42″ option adds mass but delivers serious load capacity.
- Verify stock and shipping—many sizes are in; some carry 4–6 week leads.
Grip engineering: pattern, lugs, and rim 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
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.
Tall 2”+ lugs for superior mud grip
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.
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.
| Design | Purpose | Why it helps |
|---|---|---|
| Checkmark pattern | Forward and reverse traction | Controlled recoveries and braking |
| 2″+ lugs | Self-cleaning with stability | Keeps momentum in deep sections |
| Deep wheel lip protector | Rim defense | Helps avoid rim rash and burps |
Construction & 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. This gives sidewall stiffness for stability while allowing enough flex to conform to ruts and obstacles.
It’s a tubeless lineup built specifically for UTVs. 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.
- 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.
| Spec | Effect | Action |
|---|---|---|
| 6-ply casing | Load stability and strength | Verify load ratings vs GVWR |
| Tubeless construction | Simpler installs; quick plug repairs | Keep plugs and a compressor on board |
| Non-DOT | 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.
Check load ratings and SKU notes before ordering so your choice supports passengers, gear, and the way you ride. This reduces surprises at delivery and keeps performance predictable.
Fitment tips for wheels and custom setups
A proper match between rim and profile protects finishes and improves handling.
Pick a section width that matches rim lips. An 8.5″ section usually sits well on deep rims—no pinch or balloon.
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.
Pairing with armoring custom wheels to manage debris in motion
Set offset/backspacing to clear steering/knuckles while maintaining bead protection. Dry-fit a corner to confirm caliper clearance at full lock.
- Hub-centric rings + quality lugs help keep things concentric and smooth.
- Balance mud bite with smooth feel by pairing rim/profile for swamps and trails.
- Wide-stance setups may require fender extensions to limit lug fling.
| Fitment Check | Reason | Action |
|---|---|---|
| Width vs rim lips | Avoids pinching and protects finish | Match inner/outer lip measurements |
| Beadlock ring/hardware | Can interfere with protector coverage | Measure ring depth and clamp profile |
| Offset/backspacing | Clearance for steering and brakes | 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 across terrain: mud to hard-pack
Field reports show fierce mud bite with predictable handling on hard-pack.
Unparalleled deep mud traction without sacrificing stability
Tall lugs and wide voids self-clear in clay pits and gumbo. That keeps deep mud traction during long, throttle-heavy pulls.
Checkmark geometry aids traction when pivoting or reversing. This reduces spin and helps you maintain control in sticky situations.
Smooth hard-pack ride quality for trails and flats
The carcass distributes load evenly on graded trails. With less chatter, long days feel more 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.
- Feedback notes bite + poise that maintains momentum as terrain varies.
- UTV-specific; numerous options maintain 2.5″ depth for steady off-road behavior.
| Surface | Primary Benefit | Reason it matters |
|---|---|---|
| Mud | Self-cleaning lugs | Maintains traction during long pulls |
| Hard-pack | On-center stability | Cuts fatigue; sustains speed |
| Mixed terrain | Predictable feel | Maintains momentum without twitch |
Buy confidently: inventory, lead times & U.S. shipping
Spotting in-stock vs lead-time items early avoids last-minute problems.
