Wheel modification precautions

1. Understand the parameters of the car's original wheels and tires.

2. The outside diameter of the tire must be basically the same, because this relates to the vehicle ESP stability system, instrument display and so on, so it must be basically the same with the original tire outside diameter, try to do the error within 3%, the smaller the error, the better.The outside diameter of the tire is calculated well, such as 215/60R16 tire, outside diameter =16×25.4+215×60%×2=664.4mm, the tire outside diameter after upgrading is best very close to 664.4mm.

3. The diameter and distance of the center hole of the wheel must be the same as that of the original wheel. The distance must be the same without saying much.For the diameter of the center hole, do not believe that the same effect can be achieved by adding a ring, do not do so, the stability of this will be a big problem.

4. After upgrading the tires and wheels, it is not only necessary to do dynamic balancing, but also must do a four-wheel positioning, and adjust the positioning parameters to the range set by the manufacturer.

The modified wheel is not the bigger the better, someone to improve the performance of the car and increase the wheel, under the condition of the tire diameter unchanged, the big wheel is bound to cooperate with wide and flat tires, the transverse swing of the car is small, stability is improved, like a dragonfly water, light skimming.But the flatter the tire, the thinner its thickness, the worse the shock absorption performance, comfort will make greater sacrifice.In addition, a little stone and other roadblocks cruder, tire is easy to damage.
