Tires are the most important part of your car! ! ! The engine power must pass through the tires to accelerate the car, and the braking system must pass through the tires to decelerate. Therefore, when many car owners want to modify their car when its overall performance declines, the first thing they do is the tires. But can the tires move at will? How to move better?
1. Why change?
First of all, it is indispensable to look good. The increase in size will significantly improve the appearance, and it will look handsome at first glance.
Then there is the performance aspect. For example, widening the tires can make the contact area with the ground larger and have stronger grip. The corresponding driver's control experience will be better.
When we watch racing competitions, we will find that the tires used by racers are not only very wide, but also use "hot melt tires" in order to increase more grip. As the temperature of these tires increases during driving, The tires will slowly melt, increasing the tire's grip through the stickiness of the rubber.
Therefore, effective tire modification can not only improve the appearance of the vehicle, but also have a direct impact on vehicle performance.
2. How to change it?
The first principle is performance: the load-carrying index and speed level of the replacement tires cannot be lower than those of the original tires.
The second principle is about tire size.
Add 10 and subtract 5, rim remains unchanged.
Add 20 and subtract 10, rim remains unchanged.
Add 10, subtract 10, and increase the rim by 1 inch.
Add 20, subtract 20, increase rim by 2 inches.
e.g. I want to increase the contact width between the tire and the ground and reduce the inner diameter of the tire. I choose to increase the sidewall height of the tire by 10 and decrease the aspect ratio by 10. Then the diameter of the wheel hub must be increased by 1 inch.
3. Precautions
Clarify your needs
First of all, you must clarify your needs, whether you want to improve vehicle performance, reduce fuel consumption, or be quiet and comfortable, because in some cases, different needs are contradictory to each other, such as increasing control performance while sacrificing some comfort. It is inevitable. And how to balance everyone has different ideas.
Changing the specifications of the tires will affect various performance aspects of the tires, from suspension to chassis, from braking to wet performance, from comfort to noise, and even the vehicle's speed and odometer need to be recalibrated.
