ATV / UTV Quad Bike Wheel Offset Guide

Understanding wheel offsets is essential when choosing aftermarket wheels for your ATV or UTV. Getting the wrong offset can affect handling, cause clearance issues, or prevent proper fitment. This comprehensive guide will help you select the perfect wheels for your quad bike.

What is ATV Wheel Offset?

ATV wheel offset determines where your wheel sits in relation to your vehicle. Every rim has an offset consisting of two measurements that show how the wheel is positioned around the mounting hub.

The offset uses a "+" system with two numbers:

  • First number: Distance (in inches) from the inside lip of the rim to the center hub
  • Second number: Distance (in inches) from the hub to the outside lip

Example: A wheel with 4+3 offset means:

  • 4 inches from inside lip to hub center
  • 3 inches from hub center to outside lip
  • Total rim width = 7 inches (4+3)

Positive vs Negative Offset Explained

Positive Offset

  • More rim behind the hub, less rim in front
  • First number is larger than the second number
  • Examples: 4+2, 5+2, 4+3, 5+3
  • Wheels sit closer to the vehicle
  • Most common for standard applications

Negative Offset

  • Less rim behind the hub, more rim in front
  • First number is smaller than the second number
  • Examples: 2+5, 3+4, 3+5
  • Wheels sit further from the vehicle
  • Creates wider stance and aggressive look

Choosing Correct Offsets by Suspension Type

For STRAIGHT REAR AXLE Models

FRONT Wheels:

  • Requires positive offset
  • Choose: 4+2, 4+3, or 5+2
  • First number larger than second

REAR Wheels:

  • Requires negative offset
  • Choose: 2+5, 3+5, or 3+4
  • First number smaller than second

For INDEPENDENT REAR SUSPENSION Models

You have two options:

Option 1: Same Width Rims (Front & Rear)

  • Use identical positive offset for front and rear
  • Examples: 5+2, 4+3, or 6+1
  • Can run same tire sizes or different widths on same rims
  • Simpler ordering process

Option 2: Different Width Rims

  • Front: Narrower rims with positive offset (4+2 or 4+3)
  • Rear: Wider rims with positive offset (4+4 or 5+3)
  • Mimics factory setup with different front/rear widths

Common Offset Examples

5+2 Offset (Most Standard)

  • Most popular ATV wheel offset
  • Rim face sits closer to exposed edge
  • Majority of wheel/tire sits underneath ATV
  • Standard for: Front wheels on utility ATVs/UTVs
  • Also used: Rear wheels on independent suspension models

2+5 Offset (Deep Dish)

  • "Negative offset" or "deep dish" wheels
  • Rim face recessed about 5 inches from outside edge
  • Primary use: Rear wheels on straight axle ATVs
  • Alternative use: Front and rear on IRS models for wider stance
  • Result: About 3 inches wider per side than 5+2 offset

Using Offsets to Widen Your Stance

Wide Stance Applications

  • Only available for Independent Rear Suspension models
  • Popular on: UTVs for increased stability
  • Also used on: ATVs for aggressive, extreme appearance

Achieving Wider Stance

Method 1: Negative offset wheels

  • Choose: 2+5, 3+4, or 3+5
  • Wheels extend further from vehicle

Method 2: Wheel spacers

  • Alternative to changing offset
  • Can be combined with standard offsets

Important Fitment Considerations

Before Ordering Wheels:

Check Bolt Pattern:

  • Measure both front and rear - they may differ
  • Some ATV models use different patterns front/back
  • Essential for proper wheel mounting

Verify Suspension Type:

  • Straight rear axle vs Independent rear suspension
  • Determines which offset combinations you can use
  • Affects wheel width options

Consider Your Goals:

  • Standard replacement: Match factory offset specs
  • Wider stance: Choose negative offsets (IRS only)
  • Performance: Consider handling vs stability trade-offs

Offset Impact on Performance

Positive Offset Effects:

  • Wheels sit closer to vehicle center
  • Better for narrow trail riding
  • Reduced stress on wheel bearings
  • Improved fuel economy
  • May limit ground clearance

Negative Offset Effects:

  • Wider vehicle stance
  • Increased stability at speed
  • More aggressive appearance
  • Higher stress on suspension components
  • May affect turning radius

Popular Offset Combinations by Use

Trail Riding:

  • Front: 5+2 or 4+3
  • Rear: 5+2 (IRS) or 2+5 (straight axle)

Mud Riding:

  • Front: 4+3 or 5+2
  • Rear: 2+5 for wider stance and stability

Racing/Performance:

  • Depends on: Track width regulations
  • Consider: Weight distribution and handling balance

Work/Utility:

  • Standard: 5+2 front and rear (IRS)
  • Prioritize: Durability and parts availability

Measuring Your Current Offset

Tools Needed:

  • Tape measure
  • Straight edge or ruler

Steps:

  1. Remove wheel from vehicle
  2. Lay wheel face-down on flat surface
  3. Measure from inside lip to hub mounting surface
  4. Measure from hub mounting surface to outside lip
  5. Record as first number + second number

Professional Installation Tips

  • Always verify bolt pattern before ordering
  • Check clearance for suspension components and bodywork
  • Consider tire size changes with new offsets
  • Test fit before final installation when possible
