The quest to build a faster car causes enthusiasts to spend thousands of dollars for marginal gains in performance. Some feel the need for more horsepower or a stiffer suspension, while others turn to aero bits or ECU tunes. All of these somewhat expensive modifications may positively impact performance but what if there was one mod that promised a huge increase in performance with minimal work?
On this episode of Engineering Explained, Jason Fenske uses the power of math and a physics textbook to show how to properly modify your car for a true increase in performance. He proves that doubling the horsepower of your car through whatever path you fancy, cannot compare to a set of grippy tires while lapping a circuit. This should come as no surprise as a set of good summer tires can turn your average car into a much faster machine. Although tires won’t increase your top speed or make your car louder they do allow you to access all the performance your car has to offer
Although tires won’t increase your top speed or make your car louder they do allow you to access all the performance your car has to offer. The increase in grip allows for quicker acceleration and more importantly stability around corners. When lapping a track, the ability to carry speed around corners is far more important than all-out horsepower. Now that math has clearly proved the importance of good tires, skip the cold air intake and buy a real set of tires.
