UTV Tire Size Guide: Everything You Need to Know
Tire size matters when it comes to UTV upgrades and UTV tires. Whether you're looking to increase ground clearance, boost performance, or simply enhance your machine's appearance, understanding UTV tire sizing is crucial. Let's get tire size explained in simple terms: every 2" increase in tire height adds approximately 1" of ground clearance. Good to know. Let's look into more here.
Why Tire Size Matters
Performance Benefits
- Better Obstacle Clearance: Particularly important for longer 6-seat machines traversing hills and rough terrain
- Enhanced Speed Potential: Taller tires can increase your overall speed
- Improved Trail Capability: Larger tires can help navigate challenging obstacles more effectively
- Increased Ground Clearance: As mentioned above, every 2-inch increase in tire height adds approximately 1 inch of ground clearance
Aesthetic Impact
The evolution of UTV tire sizes tells an interesting story:
- Early UTVs typically came with 25 inch tires
- Modern machines now often feature 30-inch tires as standard
- Larger tires can give older machines a more contemporary, aggressive look
- Properly sized tires help fill out wheel wells for a more proportional appearance
Critical Considerations Before Upsizing
Fitment Factors
- Fender Clearance
- Measure wheel well space carefully
- Consider articulation and suspension compression
- Factor in turning radius requirements
- Lift Requirements
- 2-3 inch lift kits may be necessary for larger tires
- Options include:
- Spring spacers
- Extended A-arms
- Portal lifts (for extreme sizes)
- Complete suspension upgrades
Performance Impact
- Power Considerations
- Larger tires can reduce low-end power
- May require clutch modifications
- Consider:
- ECM Tuning
- Clutch spring adjustments
- Clutch weight modifications
- Changing an entire clutch sheave to control shift out
- Drivetrain Stress
- Bigger tires create more torque load
- May need upgraded axles
- Consider belt grip and durability

Size Notation Explained
Using a 30x10x14 tire as an example:
- First number (30): Overall tire height in inches
- Second number (10): Tire width in inches
- Third number (14): Wheel diameter in inches
