Hi Normand, the 458 needs to be sanded down a little. You need to sand then true and on Carrera cars that often means you need extra material or you end up with too small a tire! Carrera sacrificed performance by making the stock tire small enough to clear the lights. The 21126LM tire will correct the ride height 1mm. When you get the 458 dialed in you will be spending all your energy trying to get the others equal. The 458 is the best car Carrera has produced since the Ferrari 575 Evolution.
