Preparation of tires for competition.

Over the past few years, the “control tyre” (spec tire, the control tire) in the competition of electric cars become commonplace in the U.S. and around the world. However, when you participate in a big competition or other competitions that use the “control tyre”, it is still very important to prepare the tires.

Although you no longer need (or not allowed) to experiment with the composition of the rubber, inserts, air gap and stiffnes of the tires in your set of tires, you need to take certain steps to ensure that your first

one or two runs with each set of tires will be as fast as posible. Here we look at a few things you should do immediately after unpacking the set of tires, but before apply the pasting or heat the tires.

Just keep in mind that even if your car is normally controlled better with a new set of tires, pre-mounted tires may not provide its full potential right out of the bag.

The removal of the residues of the production of the seam

All rubber tyres for cars and trucks have a noticeable seam along the center, which remained from the manufacturing proces. If the seam is large enough, it can have a negative effect on handling your car. In the worst case, the seam can cause premature los of adhesion during the competition, which can worsen the results of your first races and cause excesive heating of your tires (and this may degrade subsequent races).

The idea is to remove the seam to ensure the maximum posible contact area with the surface.
