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.
Decode sizing & match to wheel diameter
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. Larger diameters lift the chassis for ruts and bogs.
An 8.5″ section can cut through to firm base, whereas wider sections add stability on level ground.
Clearance, gearing & weight: key considerations
A 6-ply carcass provides stout sidewall support throughout the range. 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 sizes fast to match your wheel and save money.
- Pick diameter for clearance; choose width for how the tread digs into mud.
- Account for driveline and steering impacts prior to purchase.
| Item | Impact | Action |
|---|---|---|
| Diameter | Clearance and approach angles | 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 |

Grip engineering: pattern, lugs, and rim protection
This engineering prioritizes grip; every tread block, lug, and protector has a job. EFX tunes for real-world performance across mud and hard-pack.
Checkmark tread: traction in both directions
A checkmark layout interlocks lugs to increase edges. This yields predictable bite going forward and reliable reverse traction for extraction.
2”+ lugs for standout deep-mud bite
Staggered 2″+ lugs self-clean quickly and stabilize the patch in 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 protection for custom wheels trims cosmetic rash and helps maintain bead seal off-road.
| Feature | Purpose | Why it helps |
|---|---|---|
| Checkmark pattern | Two-way traction | Controlled recoveries and braking |
| 2″+ lugs | Mud evacuation and stability | Keeps momentum in deep sections |
| Deep wheel lip protector | Rim defense | Helps avoid rim rash and burps |
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. That balance yields sidewall stiffness for stability yet enough flex to conform to ruts/obstacles.
All sizes are tubeless and tuned for UTV duty. Going tubeless simplifies mounting, reduces rotating mass, and supports fast plug-type fixes.
Compliance & load/handling notes
- 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.
- Certain SKUs are oversized; plan special handling, storage, and shipping.
| Specification | Effect | Action |
|---|---|---|
| 6-ply casing | Strength and stability under load | Match load ratings to your GVWR |
| Tubeless build | Simpler installs; quick plug repairs | Carry plugs + portable compressor |
| 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. That engineered balance is what makes the ag-style tire easy claim more credible—real structure, not just big lugs.
Review load ratings and SKU notes to ensure passenger/gear support matches your riding. 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. An 8.5″ section usually sits well on deep rims—no pinch or balloon.
Verify bead and flange alignment to let the ultra deep wheel lip protector cover 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: debris control in motion
Set offset/backspacing to clear steering/knuckles while maintaining bead protection. Dry-fit one corner to confirm caliper clearance at full lock.
- Hub-centric rings + quality lugs help keep things concentric and smooth.
- 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 | Quick Action |
|---|---|---|
| Section width vs rim lip | Prevents pinching and protects finish | Compare inner/outer lip sizes |
| Beadlock ring/hardware | Can interfere with protector coverage | Measure ring depth and clamp profile |
| Offset/backspacing | Steering/brake clearance | 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.
Deep mud traction without losing 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.
Checkmark geometry aids traction when pivoting or reversing. It cuts wheelspin and keeps control when stuck.
Smooth ride on graded 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.
- 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 | Primary Benefit | Reason it matters |
|---|---|---|
| Deep mud | Self-cleaning lugs | Keeps traction through long pulls |
| Hard-pack | On-center stability | Reduces rider fatigue; keeps 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.
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.
In the U.S., many orders qualify for free shipping, but some SKUs are oversized. Expect special handling on oversized SKUs; couriers may require signatures/windows.
Quick shipping and delivery notes
- Plan ahead for lead-time SKUs if a trip is scheduled; order early to keep plans on track.
- Retailers send tracking after shipment; oversized deliveries can require someone present.
- Verify wheel specs before ordering so the feature ultra deep lip protector and armoring custom wheels benefit your rims right away.
- These are tubeless and non-DOT—mount for off-road use only and keep plugs and a compressor handy for field repairs.
