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. Match that final number to your rim to prevent extra expense and fitment problems.
Choose by terrain balance
Decide between maximum mud bite or a calmer hard-pack feel. Going larger increases clearance for ruts and bogs.
Narrower sections, such as 8.5″, help the profile cut through mud to firmer layers, while wider choices spread contact for stability on flats.
Mind clearance, gearing, and weight
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.
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 size codes quickly to match your rim and avoid extra cost.
- Pick diameter for clearance; choose width for how the tread digs into mud.
- Account for driveline and steering impacts prior to purchase.
| Item | Effect | Action |
|---|---|---|
| Diameter | Ground clearance, approach angle | Choose larger for deep mud runs |
| Section width | Penetration vs flotation | Use narrower to punch through mud |
| Tire weight | Rotational load and acceleration | Check clutching/gearing accordingly |

Fast conclusions:
- Leverage the chart to weigh acceleration feel vs passenger/cargo support.
- Uniform tread depth lets lugs dig in mud yet stay predictable 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.
- Check availability and free shipping notes—many are in stock, some list 4–6 week lead times.
Grip engineering: pattern, lugs, and rim 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. This yields predictable bite going forward and reliable reverse traction for extraction.
2”+ lugs for standout deep-mud bite
With 2″+ staggered lugs, mud sheds quickly and the patch stays stable in ruts. Reinforced grooves and shoulder blocks add lateral grip so side-hilling feels planted, not sketchy.
A deep wheel-lip protector guards bead lips and deflects debris from the bead. This protection for custom wheels trims cosmetic rash and helps maintain bead seal off-road.
| Design | Purpose | Notes |
|---|---|---|
| Checkmark pattern | Forward and reverse traction | Predictable extraction and braking |
| Tall lugs | Mud evacuation and stability | Confidence in deep muck |
| Lip protector | Rim defense | Helps avoid rim rash and burps |
Construction & 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. You get sidewall stiffness for stability plus flex to contour over 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
- These are non-DOT; off-road/private property only—avoid public roads needing DOT.
- Weights vary by SKU (~36–81 lb); most list 2.5″ tread depth and max loads ~740–1390 lb.
- Oversized SKUs may need special handling, storage, and shipping arrangements.
| Specification | Impact | Recommended action |
|---|---|---|
| 6-ply carcass | Strength and stability under load | Match load ratings to your GVWR |
| Tubeless build | Simpler installs; quick plug repairs | Keep plugs and a compressor on board |
| 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. That engineered balance is what makes the ag-style tire easy claim more credible—real structure, not just big lugs.
Verify load ratings/SKU notes to confirm support for passengers, cargo, and riding style. This reduces surprises at delivery and keeps performance predictable.
Fitment tips for wheels and custom setups
Get rim/profile fit right to protect finishes and refine handling.
Choose a section width that aligns with your wheel lips. The common 8.5″ option fits deep rims well without pinching/ballooning.
Check bead/flange alignment so the deep lip protector fully covers the rim. Proper alignment maximizes armoring custom wheels while preventing exposed edges.
For beadlocks, double-check ring thickness and clamp geometry so the protector clears hardware on concave or wide faces.
How to pair with armoring custom wheels for debris management
Mind offset/backspacing so the protector clears tie rods/knuckles yet still shields the bead. 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.
- Aggressive/wide builds often benefit from fender extensions to manage fling.
| Fitment Check | Why it Matters | Quick Action |
|---|---|---|
| Section width vs rim lip | Prevents pinching and protects finish | Compare inner/outer lip sizes |
| Beadlock hardware | Can interfere with protector coverage | Measure ring depth and clamp profile |
| Offset & backspace | Steering/brake clearance | Confirm before final purchase |
EFX’s thoughtful protector geometry rewards careful wheel selection. Result: fewer chips from custom wheels debris and cleaner rims after muddy weekends.
Performance by terrain: mud → hard-pack
Field reports show fierce mud bite with predictable handling on hard-pack.
Unparalleled deep mud traction without sacrificing stability
In clay pits and gumbo, tall lugs and wide voids help with self-cleaning. This preserves 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.
Composed hard-pack ride on trails and flats
On graded routes, the carcass spreads load over the patch. With less chatter, long days feel more comfortable.
Going from wet sections to hard-pan remains predictable. Stability beats twitchiness, helping carry speed on connectors.
- Better flotation and rut-bridging than small knobbies, with modest steering effect.
- 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.
| Terrain | Main benefit | Why it Matters |
|---|---|---|
| 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 |
