How do bigger tires affect my ATV or UTV performance?
Bigger tires can reduce gas mileage and slightly increase braking distances due to the added weight and rolling resistance, but can also improve ride quality thanks to a taller sidewall. The trade offs are manageable with the right tire choice and a proper tune after installation.
Upgrading to larger tires is one of the most common ATV and UTV modifications, but it involves real trade-offs worth understanding before you buy.
Ground clearance: The main benefit -- bigger tires raise the machine off the ground, helping you clear obstacles on the trail without dragging.
Fuel consumption: Larger, heavier tires increase rotational mass, requiring more power to turn. Expect reduced fuel economy and additional strain on the drivetrain -- especially notable on side-by-sides with belt-driven CVT transmissions.
Performance and speed: More rolling mass generally reduces acceleration. Top speed can vary depending on gear ratios and how significantly the overall tire diameter changed.
Ride quality: Taller tires with more sidewall can absorb trail vibration better than low-profile setups. However, if the tires are overinflated for the terrain, ride quality suffers.
Braking: More contact patch generally means better traction for stopping, but the added mass means more momentum to scrub off.
A lift kit is often needed to accommodate significantly larger tires without fender or suspension contact. Browse lift kits in our suspension catalog.
