motohavok tire size: how to choose the perfect fit right now
Choose correctly by reading sidewall numbers and aligning them with your wheels and 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 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.
Mind clearance, gearing, and weight
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 size codes quickly to match your rim and avoid extra cost.
- Choose diameter for clearance; use width to tune cut-through vs float.
- Plan ahead for steering/driveline effects.
| Item | Effect | Action |
|---|---|---|
| Diameter | Ground clearance, approach angle | Go larger for deep mud and ruts |
| Section width | Cut-through vs float | Run narrower to cut to firm base |
| Tire 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. 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.
| Feature | Benefit | Why it helps |
|---|---|---|
| Checkmark geometry | Forward and reverse traction | Controlled recoveries and braking |
| Tall lugs | Self-cleaning with stability | Keeps momentum in deep sections |
| Deep wheel lip protector | Rim defense | Reduces rim damage and burping |
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. 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. Tubeless mounting eases installation, lowers rotating mass versus tubes, and lets you manage punctures quickly with plugs.
Compliance, loads, and 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.
- 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 | Recommended action |
|---|---|---|
| 6-ply carcass | Load stability and strength | Match load ratings to your GVWR |
| Tubeless build | Easier mounting; puncture repair options | Carry plugs + portable compressor |
| Non-DOT | Off-road use only | Limit use to trails and private land |
Despite the aggressive look, the casing is tuned to deliver a more composed ride than many ag-style tire competitors. Engineering—not just big lugs—underpins the ag-style performance balance.
Review load ratings and SKU notes to ensure passenger/gear support matches your riding. This reduces surprises at delivery and keeps performance predictable.
Wheel fitment guidance for custom builds
Get rim/profile fit right to protect finishes and refine handling.
Choose a section width that aligns with your wheel lips. An 8.5″ section usually sits well on deep rims—no pinch or balloon.
Check bead/flange alignment so the deep lip protector fully covers the rim. Proper alignment maximizes armoring custom wheels while preventing exposed edges.
With beadlocks, confirm ring/clamp shapes so the protector clears hardware on wide/concave faces.
Pairing with armoring custom wheels to manage debris in motion
Mind offset/backspacing so the protector clears tie rods/knuckles yet still shields the bead. Test-fit a corner to verify full-lock caliper clearance.
- Run hub-centric rings and quality lugs for concentric fit and less vibration.
- 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.
| Check | Why it Matters | Action |
|---|---|---|
| Section width vs rim lip | Prevents pinching and protects finish | Match inner/outer lip measurements |
| Beadlock hardware | Can interfere with protector coverage | Check ring depth and clamp geometry |
| Offset & backspace | 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.
From mud to hard-pack: performance overview
Real-world runs show the pack delivers both fierce grip in muck and predictable manners on firm ground.
Serious mud grip with consistent stability
In clay/gumbo, tall lugs and wide voids self-clean effectively. This preserves deep-mud traction during long, throttle-heavy pulls.
The checkmark layout supports traction moves for pivots or backing out. That limits spin and helps maintain control in sticky spots.
Smooth hard-pack ride quality for 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.
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/rut bridging beat small knobbies with minimal steering penalty.
- Riders report a balance of bite and poise that keeps groups moving as terrain changes.
- UTV-focused design; many sizes keep 2.5″ depth for consistent off-road results.
| Terrain | Main benefit | Why it Matters |
|---|---|---|
| Mud | Self-clearing lugs | Maintains traction during long pulls |
| Hard-pack | On-center stability | Reduces rider fatigue; keeps speed |
| Mixed runs | Predictable feel | Maintains momentum without twitch |
Buy with confidence: inventory status, lead times, and shipping in the United States
Knowing what ships now vs what has multi-week leads prevents last-minute stress.
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.
U.S. orders frequently qualify for free shipping, though some SKUs are marked as oversized items. Oversized listings often require special handling, and carriers may ask for a signature or specific delivery windows.
Fast shipping notes
- Plan ahead for lead-time SKUs if a trip is scheduled; order early to keep plans on track.
- Expect tracking updates from retailers once a set ships; oversized deliveries may need someone present to accept.
- Verify wheel specs pre-order so the ultra-deep lip protector and armoring custom wheels protect your rims immediately.
