Tire size is one of the biggest performance changers on a UTV. Go too big and you lose power and rub everywhere. Go too small and you lose ground clearance.
Here’s the simple breakdown that applies to most modern machines:

Stock Sizes (Common Ranges)

• 28–30” = stock or close to it

• 32” = common upgrade

• 33–35” = big tire setups

• 37”+ = mud setups with gearing or clutch changes

What to Watch For

• Fender clearance

• Wheel offset

• Clutching changes

• Axle angles

• Steering radius

Quick Rule of Thumb

Every 1” of tire height adds roughly ½” of ground clearance.
