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 the wheel number to your current wheel to avoid extra cost and fitment headaches.
Pick based on terrain needs
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. 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.
- Choose diameter for clearance; use width to tune cut-through vs float.
- Plan for driveline and steering changes before upgrading.
| Item | Impact | Action |
|---|---|---|
| Diameter | Ground clearance, approach angle | Choose larger for deep mud runs |
| Section width | Cut-through vs float | Run narrower to cut to firm base |
| Weight | Rotational mass, acceleration | Verify clutching and gearing |

Engineering for grip: tread, lugs & wheel protection
Engineering here puts grip first, so every tread, lug, and protector earns its place. EFX targets practical performance from muck to hard-pack.
Industry-first checkmark tread for traction in drive and reverse
The checkmark pattern interlocks lugs to create extra biting edges. That gives predictable traction when you head forward and when you need traction drive reverse to extract from a hole.
Enormous 2”+ lugs for unparalleled deep mud performance
Staggered 2″+ lugs self-clean quickly and stabilize the patch in 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 geometry | Two-way traction | Predictable extraction and braking |
| Tall lugs | Mud evacuation and stability | Keeps momentum in deep sections |
| Lip protector | Wheel protection | Reduces rim damage and burping |
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. That balance yields sidewall stiffness for stability yet enough flex to conform to ruts/obstacles.
The lineup is tubeless and optimized for UTV use. Tubeless fitment speeds installs, cuts rotating mass vs tubes, and enables quick plug repairs.
Load and handling considerations
- 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.
| Spec | Effect | Recommended action |
|---|---|---|
| 6-ply carcass | Strength and stability under load | Match load ratings to your GVWR |
| Tubeless construction | Simpler installs; quick plug repairs | Keep plugs and a compressor on board |
| Non-DOT rating | 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.
Review load ratings and SKU notes to ensure passenger/gear support matches your riding. That helps avoid delivery surprises and preserves predictable results.
Fitment guidance for wheels and custom builds
A proper match between rim and profile protects finishes and improves handling.
Pick a section width that matches rim lips. The common 8.5″ option fits deep rims well without pinching/ballooning.
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.
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
Consider offset and backspacing so the protector clears tie rods and knuckles while still shielding 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 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 | Why it Matters | Quick Action |
|---|---|---|
| Width vs rim lips | Avoids pinching and protects finish | Compare inner/outer lip sizes |
| Beadlock hardware | Can interfere with protector coverage | Check ring depth and clamp geometry |
| Offset & backspace | Clearance for steering and brakes | Verify prior to purchase |
EFX’s thoughtful protector geometry rewards careful wheel selection. Result: fewer chips from custom wheels debris and cleaner rims after muddy weekends.
From mud to hard-pack: performance overview
In real rides, this lineup brings strong muck grip with predictable behavior on firm ground.
Deep mud traction without losing stability
Tall lugs and wide voids self-clear in clay pits and gumbo. This preserves deep-mud traction during long, throttle-heavy pulls.
The checkmark layout supports traction moves for pivots or backing out. 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. Hands and shoulders feel less chatter, so long days stay comfortable.
Going from wet sections to hard-pan remains predictable. You get stability—not twitch—so connectors can be taken with confidence.
- 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 | Primary Benefit | Reason it matters |
|---|---|---|
| Deep mud | Self-clearing lugs | Maintains traction during long pulls |
| Hard-pack | On-center stability | Cuts fatigue; sustains speed |
| Mixed terrain | Predictable feel | Keeps momentum without twitchiness |
Inventory, lead times, and U.S. shipping: buy with confidence
Knowing what ships now vs what has multi-week leads prevents last-minute stress.
A lot of popular sizes list “In Stock & Ready To Ship” on retailer 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. shipments often ship free; certain SKUs are oversized. Oversized items may need special handling; carriers can require signatures or scheduled windows.
Fast shipping notes
- If a trip is coming, plan for lead-time items and order early.
- You’ll get tracking once shipped; oversized items may need in-person acceptance.
- Verify wheel specs pre-order so the ultra-deep lip protector and armoring custom wheels protect your rims immediately.
