Range loss from larger wheels and tires depends on several factors, including wheel size, tire width and rolling resistance, suspension changes, and driving speed. Moving from OEM 18-inch wheels to 20-inch wheels typically increases rolling resistance by about 8 to 15%, which often translates to roughly a 5 to 10% reduction in EPA range on highway driving cycles for most Tesla models.
Tire choice can have an even bigger impact. Summer performance tires can reduce range by around 10 to 15% compared to OEM all-season tires, and winter tires may reduce range by 15 to 25% due to higher rolling resistance plus colder temperatures and winter driving conditions. When you combine larger wheels with high-performance tires, total range loss can reach 20 to 25%. For a vehicle rated at 300 miles EPA, that can mean roughly 60 to 75 miles less range.
To reduce the hit while still running wider wheel and tire setups, prioritize low rolling resistance tires. Look for models marketed as LRRC (low rolling resistance), including options from Michelin, Pirelli, and Continental, since these can meaningfully reduce the efficiency penalty.
Wheel weight matters too. Added unsprung weight increases the energy required for acceleration and can add load to the suspension and brakes. Lighter forged wheels help compared to heavier cast wheels, and the weight savings from forged wheels can often recover about 2 to 4% of the range loss from upsizing.
Wheel design can also affect aerodynamics. Designs with a lot of exposed face area, deep profiles, or exposed hardware can add drag compared to more aero-optimized shapes, sometimes contributing an additional 3 to 5% efficiency penalty.
In winter climates, wider winter tires on larger wheels can still be worth it for safety, since improved traction and control may outweigh the efficiency trade-off. The best approach is to estimate your likely range impact before buying so you can choose the wheel size and tire compound that match your priorities for handling, appearance, efficiency, and seasonal driving.
