motohavok tire size: how to choose the perfect fit right now
Select accurately by decoding sidewall sizes and matching them to wheel specs and ride priorities.
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. Match that final number to your rim to prevent extra expense and fitment problems.
Pick based on terrain needs
Choose if you prefer peak mud traction or steadier hard-pack manners. Bigger diameters raise chassis height for ruts/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.
Clearance, gearing & weight: key considerations
The common 6-ply carcass construction gives strong sidewall support across the lineup. However, taller/heavier sizes add rotating mass and can affect acceleration and CVT response.
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 | What to do |
|---|---|---|
| Overall diameter | Clearance and approach angles | Choose larger for deep mud runs |
| Tire width | Penetration vs flotation | Use narrower to punch through mud |
| Weight | Rotational load and acceleration | Verify clutching and gearing |

- Confirm stock status—numerous sizes ship now; others show 4–6 week waits.
Engineering that grips: tread pattern, lug design, and wheel protection
Here the design focuses on grip—each tread element and protector is purposeful. EFX targets practical performance from muck to hard-pack.
Checkmark tread: traction in both directions
Checkmark geometry interlocks blocks for added biting 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 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. This protection for custom wheels trims cosmetic rash and helps maintain bead seal off-road.
| Design | Benefit | Notes |
|---|---|---|
| Checkmark pattern | Two-way traction | Predictable extraction and braking |
| 2″+ lugs | Mud evacuation and stability | Confidence in deep muck |
| Lip protector | Wheel protection | Helps avoid rim rash and burps |
Construction and 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. 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.
- Expect ~36–81 lb weight range, common 2.5″ depth, and max loads near 740–1390 lb.
- Some SKUs are oversized items—plan for special handling, storage, and shipping on larger orders.
| Spec | Impact | Action |
|---|---|---|
| 6-ply casing | Load stability and strength | Verify load ratings vs GVWR |
| Tubeless construction | Easier mounting; puncture repair options | Carry plugs + portable compressor |
| Non-DOT | Off-road use only | Limit use to trails and private land |
Although aggressive in appearance, the casing is tuned for calmer ride quality than many ag-style rivals. 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. This reduces surprises at delivery and keeps performance predictable.
Fitment tips for wheels and custom setups
Matching rim and profile correctly protects finishes and sharpens handling.
Pick a section width that matches rim 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. 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
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.
- Use hub-centric rings and quality lugs to keep the assembly concentric and reduce vibration.
- Match rim/profile to balance mud grip and smooth trail manners.
- Wide-stance setups may require fender extensions to limit lug fling.
| Check | Reason | Quick Action |
|---|---|---|
| Section width vs rim lip | Avoids pinching and protects finish | Match inner/outer lip measurements |
| Beadlock hardware | May interfere with protector | Check ring depth and clamp geometry |
| Offset/backspacing | Clearance for steering and brakes | Confirm before final purchase |
EFX’s protector geometry pays off when wheels are chosen carefully. The result: fewer chips from custom wheels debris and cleaner rims after a muddy weekend.
From mud to hard-pack: performance overview
In real rides, this lineup brings strong muck grip with predictable behavior on firm ground.
Serious mud grip with consistent stability
Tall lugs and wide voids self-clear in clay pits and gumbo. This preserves 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 hard-pack ride quality for trails and flats
On graded routes, the carcass spreads load over the patch. With less chatter, long days feel more comfortable.
When you hop from puddles to hard-pan, the contact patch transitions predictably. You get stability—not twitch—so connectors can be taken with confidence.
- 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 |
|---|---|---|
| Deep mud | Self-cleaning lugs | Keeps traction through long pulls |
| Hard-pack | On-center stability | Reduces rider fatigue; keeps speed |
| Mixed runs | Predictable transitions | Keeps momentum without twitchiness |
