Range is a result of multiple factors. Perhaps the largest being the tire selection itself. We suggest for people focused on range to select a tire that is equal to or more efficient of a tread pattern and rubber compound as the factory tire and keeping the tires inflated to optimum manufacturer suggested PSI for maximum range. A softer rubber compound and more sporty tire, or a larger width tire in both circumstances will typically decrease range quite a lot. Secondarily, is the factor of wheel weight and design. The EVT turbine is on average 1-2lbs lighter in construction per wheel than other turbines in the market, this factor will help range comparatively. Depending on your vehicle and your factory wheel configuration the EVT wheel may be slightly less heavy or slightly more heavy. Exact answers are scientifically difficult to prove side by side due to temperature, road conditions, driver variances, tire PSI, and subtle variances between cars.
