EV Tires vs traditional tires, what’s the difference?
Analysts estimated over 60% of global car production will be electric vehicles by 2040 so tire manufacturers have started to engineer specific EV tires to enhance the performance of EVs and support global growth in EVs.
One of the biggest questions we get from customers: What’s the difference between an EV Tire and a traditional tire?
Noise Reduction - This is probably the biggest difference of an EV Tire vs a traditional tire. Noise reduction on EV tires is mainly addressed by installing foam sheets inside the tire. In addition the type of rubber compound as well as tread pattern also assist in noise reduction.
Reduced Rolling Resistance - Lower rolling resistance of a tire results in less energy loss and will retain vehicle range. Techniques to reduce rolling resistance include but are not limited to the type of rubber compound, which can lead to lighter weight, tire tread patterns and the shape of the tire profile.
Durable Material - Newer tire compounds are needed to support the EV driving experience. A combination of high load resins and silica natural resources are key ingredients to EV specific tires. With better material durability comes better power delivery and driving experience versus traditional material.
Tire Load - EV tires generally have larger load ratings than traditional tires. A perfect example is a Pirelli 235/35/20, which is the Model 3 20” factory tire size. Pirelli manufactures this tire in 2 load ratings, an 88 and a 92. An 88 tire holds a max load of 1,235 lbs while a 92 holds a max load of 1,389. With no surprise, the 235/35/20 88 load tire is a Porsche 911 factory tire, while the 235/35/20 92 is a Tesla factory tire. Heavier tire loads for EV’s are essential for performance.
Improved Traction - EVs have an insane amount of torque. To maintain traction, EV tires have wide treads toward the center of the tire to reduce slippage. Also the treads will have jagged grooves to prevent hydroplaning and the increased torque.
